Create a program that calculates and prints the amount of change to be returned to the customer after paying the bill, based on the manager's input in the system. Sample Input: Total Invoice amount(In Dollars): 200 Amount of Tip (In cents): 10 Total Payment received by card: 160 Service Charged on payment made by card: 4% Total Payment received in Cash(In Dollars): 100 Output: Change to be returned to the customer (In Dollars): 53.50 Note: If the return to the customer is negative, then it must print 'outstanding amount and need to be paid by customer:', and the amount need to be paid # Python solution: def calculate_change(invoice_amount, tip_amount, card_payment, service_charge, cash_payment): # Convert service charge percentage to decimal service_charge_decimal = service_charge / 100 # Calculate total payment made by card (including service charge) total_card_payment = card_payment * (1 + service_charge_decimal) # Calculate total payment (card + cash) total_payment = total_card_payment + cash_payment # Calculate the change to be returned change = total_payment - (invoice_amount + tip_amount) return change # Get user input invoice_amount = float(input("Total Invoice amount (In Dollars): ")) tip_amount = int(input("Amount of Tip (In cents): ")) card_payment = float(input("Total Payment received by card: ")) service_charge = float(input("Service Charged on payment made by card (%): ")) cash_payment = float(input("Total Payment received in Cash (In Dollars): ")) # Calculate and print the change change = calculate_change(invoice_amount, tip_amount, card_payment, service_charge, cash_payment) if change >= 0: print(f"Change to be returned to the customer (In Dollars): {change:.2f}") else: print(f"Outstanding amount and need to be paid by customer: {-change:.2f}") This program takes user inputs for the invoice amount, tip amount, card payment, service charge percentage, and cash payment. It then calculates the total payment, including the service charge, and determines the change to be returned. If the change is negative, it prints the outstanding amount that needs to be paid by the customer

In this lesson, we will cover the fundamental building blocks and common patterns. Basic Elements: 1. Literal Characters: • A regular expression can consist of literal characters that match exactly. For example, the regex `python` will match the string "python" in a text. 3. Character Classes: • Character classes are enclosed in square brackets ([]) and allow you to match any one of the characters within the brackets. For instance, `[aeiou]` matches any vowel. 5. Quantifiers: • Quantifiers specify how many times a character or group should appear. The asterisk `*` means zero or more occurrences, the plus `+` means one or more occurrences, and the question mark `? ` means zero or one occurrence. 7. Wildcards: • The dot (`.`) serves as a wildcard, matching any character except a newline. For example, `b.t` would match "bat," "bit," "but," etc. Examples: 1. Literal Characters: • Regex: `cat` • Matches: "cat" in "The cat is black." 4. Character Classes: • Regex: `[aeiou]` • Matches: Any vowel in "apple" or "orange." 7. Quantifiers: • Regex: `lo+l` • Matches: "lool" or "loooool" in "The cat is looking." 10. Wildcards: • Regex: `b.t` • Matches: "bat," "bit," "but," etc., in "The bat is in the box." Exercise: Write Simple Regular Expressions to Match Specific Patterns 1. Match Dates: • Write a regex pattern to match dates in the format "YYYY-MM-DD." Test it against strings like "2022-01-01" and "2023-12-31." 3. Match Email Addresses: • Create a regex pattern to match basic email addresses. Test it against strings like "user@example.com"(mailto:user@example.com) and "john_doe123@gmail.com.(mailto:john_doe123@gmail.com)" 5. Match Phone Numbers: • Develop a regex pattern to match standard U.S. phone numbers in the format "(XXX) XXX-XXXX." Test it against numbers like "(555) 123-4567." 7. Match Hexadecimal Colors: • Construct a regex pattern to match hexadecimal color codes, such as "#RRGGBB." Test it against strings like "#1a2b3c" and "#ff9900." Remember to use online regex testers or Python's re module to validate and test your patterns against different strings. Practice refining your patterns based on the results and experiment with variations of the exercises.

Regular expressions (regex or regexp) are powerful and concise sequences of characters that define search patterns. They serve as a flexible tool for text processing, allowing you to describe and match complex patterns within strings. Regular expressions are widely used in programming, data validation, text manipulation, and search operations. Key Concepts: 1. Pattern Matching: • At its core, a regular expression is a pattern that describes a set of strings. It allows you to search for, match, and manipulate text based on this pattern. 3. Text Search and Manipulation: • Regular expressions provide a way to search for specific sequences of characters, validate input formats, replace text, and extract information from strings. 5. Concise Syntax: • Regular expressions have a concise syntax that enables you to express complex patterns using a relatively small amount of code. This makes them efficient for tasks involving text processing. 7. Versatility: • Regular expressions are not limited to a specific programming language or tool. They are supported across various programming languages, command-line utilities, and text editors. 9. Common Use Cases: • Regular expressions find applications in tasks such as data validation, parsing logs, searching for patterns in text files, and extracting information from structured data. Benefits: • Efficiency: • Regular expressions allow you to perform powerful text manipulations with minimal code, leading to more efficient and readable solutions. • Flexibility: • They provide a high degree of flexibility, allowing you to create patterns that match specific criteria and adapt to different scenarios. • Pattern Reusability: • Once you've defined a regular expression pattern, you can reuse it across multiple instances, promoting code reusability and maintainability. Applications: 1. Text Search: • Regular expressions excel at searching for specific patterns within text. Whether you're looking for keywords, dates, or other structured data, regex can help you locate and extract relevant information. 3. Data Validation: • Regular expressions are widely used for validating input formats. Whether it's email addresses, phone numbers, or credit card numbers, regex can help ensure that the data meets the required criteria. 5. Search and Replace: • Beyond just searching, regular expressions enable you to replace or modify text based on specific patterns. This is particularly useful when you need to make bulk changes to a document or dataset. 7. Validate with Regular Expressions: • Regular expressions can be employed to validate data against predefined patterns. For example, you can use regex to verify if a given string is a valid email address, adheres to a specific date format, or follows a custom pattern. Regular expressions are a fundamental tool in a programmer's toolkit, offering a concise and powerful way to work with textual data. Understanding how to construct and use regular expressions effectively can significantly enhance your ability to manipulate and analyze text in various programming and scripting contexts.

You can do this by including the field names in your query, and adding a 1 or 0 next to them, to specify whether it should be returned or not. This is a projection parameter. A projection parameter of 1 will display the field and a 0 will hide it. Example First let's do a query without projection (so we can see how many fields are returned): Without Projection: >db.inspections.find( {"result": "Violation Issued"} ) Result: With Projection Now, let's use projection to display just the name field: db.inspections.find( { "result": "Violation Issued" }, { "_id":0,"date": 1 ,"result":1} ) Result: You will notice that the _id field is automatically included, even if you don't specify it. You can exclude this field by using a 0 against it: db.inspections.find( { "result": "Violation Issued" }, { _id: 0, "date": 1 } ) Result: You can't mix 1s(inclusion) and 0s(Exclusion) db.inspections.find( { "result": "Violation Issued" }, { "date": 1, "sector":0 } ) You'll end up with this error: Error Result: -------------------------------------------------------------------------------------------------- MongoDB - Limit the Results of a Query -------------------------------------------------------------------------------------------------- Return only the number of documents you need with the limit() method In MongoDB, you can use the limit() method to specify a maximum number of documents for a cursor to return. When you query a collection using the db.inspections.find() method, you can append limit() to specify the limit. Example First let's do a query without a limit (so we can see how many documents are returned): Without a Limit db.inspections.find( { "result": "Violation Issued" }, { "date": 1 } ) Result: OK, so let's limit the results to say, 3 documents: With a Limit db.inspections.find( { "result": "Violation Issued" }, { "date": 1 } ).limit(3) Add the skip() Method You can use the skip() method to skip to a document within the cursor db.inspections.find( { "result": "Violation Issued" }, { "date": 1 } ).limit(3).skip(1) Result: Skip first result and display next three result Note that skip() can be used on any query (not just ones with limit()). -------------------------------------------------------------------------------------- MongoDB - Sort the Results of a Query --------------------------------------------------------------------------------------- The sort() method specifies a sort order for the cursor. It will typically contain one or more fields, each followed by either 1 or -1, depending on whether the sort should be in ascending or descending order. With sort() in Ascending Order A value of 1 next to a field name specifies that the documents should be sorted by the specified field in ascending order. Here we sort the results by name in ascending order: db.inspections.find( ).sort( { "date": 1 } ) With sort() in Descending Order A value of -1 next to a field name specifies descending order. Here we sort the results by name in descending order: db.inspections.find( ).sort( { "date": -1 } ) Multiple Fields db.inspections.find( ).sort( { "result": 1, "date": -1 } ) Result: Sort with Limit db.inspections.find( ).limit(3).sort( { "result": 1} ) MongoDB - Create a Relationship To create a relationship in MongoDB, either embed a BSON document within another, or reference it from another. One-to-One Relationship One-to-Many Relationship Querying the Relationship you can use $lookup to perform a left outer join on the two collections.This, in conjunction with the aggregate() method, and $match. Example: db.collection1.aggregate([ { $lookup: { from: "collection2", localField: "_id", foreignField: "artist_id", as: "band_members" } }, { $match : { artistname : "Rush" } } ]).pretty() Collection of employee MongoDB shell version v4.0.9 connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb Implicit session: session { "id" : UUID("153d94df-eb08-41ff-8348-6e2790efc0bc") } MongoDB server version: 4.0.9 Server has startup warnings: 2019-06-08T17:41:59.265+0530 I CONTROL [initandlisten] 2019-06-08T17:41:59.265+0530 I CONTROL [initandlisten] ** WARNING: Access contr ol is not enabled for the database. 2019-06-08T17:41:59.265+0530 I CONTROL [initandlisten] ** Read and wri te access to data and configuration is unrestricted. 2019-06-08T17:41:59.265+0530 I CONTROL [initandlisten] --- Enable MongoDB's free cloud-based monitoring service, which will then receive an d display metrics about your deployment (disk utilization, CPU, operation statistics, etc) .

Assignment 3: RMI + Hibernate – See Brightspace for due date. Read the requirements carefully, if your program does not meet the requirements expect a loss of marks for the assignment, even though your program code runs without errors. Refer to the Course Section Information (CSI) document posted in Brightspace under Course Information for additional requirements common to all assignments. Lab Partner: Optional For this lab, you may work with a lab partner. Your lab professor must be notified via email of partners with names before the due date. Please include lab section number. Both members must be registered in the same lab section. Both partners must demonstrate their program in lab together as a pair, all code files and other documents must have both members full names. Both partners need to submit the assignment in full to Brightspace, your lab professor will select one student’s submission and use it as the grade for both partners. Ensure that both submissions are the same. Description You are to develop an RMI-Hibernate-based 3-tier (Console User Interfaces, Client, Server, Database) networked multi-user version of Assignment 2. RMI will be used instead of Network socket communications, using only Tuna objects as transfer objects. The data access layer logic will have JDBC replaced with Hibernate. Setup Create an Assignment 3 project in Eclipse Add the Hibernate and ConnectorJ external Jar files as seen in lecture. Copy the starter code into your project Reference the Hibernate demo 2 from lecture – EchoClient & EchoServer with RMI and Hibernate Log into MySQL and create a user account ‘assignment3’ with password ‘password’ as well as a database ‘assignment3’ (examine the hibernate.cfg.xml file to ensure it matches your settings). There is no database script, your annotated Tuna Entity should permit Hibernate to create the database tables for you when your project runs. ToDo: datatransfer.Tuna Add annotations: Entity, with table name “tunas” primary key should be generated by MySQL and not left up to Hibernate String fields should be represented by database columns with sizes of 42 characters. isLastTuna should be annotated as @Transient Note: Older Hibernate used a mapping file, do not do this, use Annotations in your Entity class. ToDo: dataaccesslayer. TunaDaoImpl This is an enum, with one constant inside named INSTANCE. i.e. Singleton design pattern. Using Safari Books in the Library, look up: Joshua Bloch. (2008). Effective Java, Second Edition. Addison-Wesley Professional. ISBN-13: 978-0-321- 35668-0 and See Item 3: Enforce the singleton property with a private constructor or an enum type. The private constructor should construct the SessionFactory The insert method should use a Hibernate Session to insert a Tuna into the database The findByUUID should accept a String based uuid, to lookup a Tuna in the database, and return it. Make sure that Hibernate sessions are closed in their respective methods, and that the shutdown method closes the session factory and destroys the registry. ToDo: server. TunaServiceImpl This implements the remoteinterface.TunaService (which in turn extends java.rmi.Remote). Each method (insert, findByUUID) should use the TunaDaoImpl.INSTANCE to either insert or findBy as needed. (There really should not be much code here.) Note: The shutdown method is provided to you, there is no mistake that it is missing from the TunaService interface, and that there is no @Override on it either. We do not want to permit any clients to call shutdown(), only the server-side code should be able to call the shutdown() method. ToDo: server.TunaServer Typical RMI startup, should instantiate a TunaServiceImpl and export it to the registry, then bind it as “TunaService” See comments in the main method for instructions. ToDo: client.TunaClient You can use either the Hibernate Demo 2 client, or your Assignment 2 client as starter code. Obtain a connection to the RMI server, to the remote TunaService Ask the user for the data for a Tuna, then ask the remote object to insert it, then ask for a Tuna back with the generated primary key value (the client should send the UUID as a String). Ask the user if they want to continue, or shutdown if an Exception is generated by the server. Note: There is no Message object, no String commands, use RMI to make method calls against the remote object. Demonstration in lab Demonstrate that the server runs, a client runs, and the client can insert a record into the database Demonstrate that if the MySQL service is shutdown, while your server and client are running, that the client shuts down gracefully when the server encounters exceptions. Documentation Javadoc All classes, interfaces, and class/interface members need Javadoc comments in code files Place your name(s) at the top of each source code file. There is no need to generate html using the Javadoc tool. UML Sequence Diagram Diagram the sequence of client requesting a Tuna to be created. Diagram the sequence of client requesting a Tuna based on UUID. You may use the one diagram to show both sequences. I am not requesting a test plan for Assignment 3. Short Answer Questions What are some advantages and drawbacks of using RMI versus network sockets for a client-server application? What are some advantages and disadvantages of using Hibernate instead of JDBC for a data-connected application?

The first phase of the project involves the design of the database. In this phase you need to design a database that maintain all the "Contracts" of a company. The Contract Management System (CMS) will serve the employees, managers and other stakeholders in the enterprise. You should use MySQL DBMS to implement the database system and show its execution by queries. Problem Statement: Following are the requirements for the CMS that you are going to develop. P-1) CMS system should maintain information about: 1. Departments - (Development, QA, UI, Design, Business Intelligence, Networking) 2. Contracts - (Premium, Gold, Diamond, Silver) 3. Managers - (Manager responsible for the contract) 4. Employees - (Employee ID) 5. Dept.- Employee 6. Dept.- Manager P-2) A sales associate dealing with the client must capture the following information about the contract: 1. Name of the company and the responsible of the company (First name, Last name, middle initial) who is signing the contract. 2. Contact Number - (Count the number of digits). 3. Email-id of the company. 4. Address City, Province and Postal code – Data should be only of Canada (All provinces). 5. Annual Contract Value (ACV): in dollar. 6. Initial Amount – Every Entry should be double. (ex. $101.23) 7. Service start date: Automatically allocate today’s date from system date to each contract. 8. Type of service: (Cloud, On-premises). You need to complete the database design, implement the database, collect appropriate data and store them into the database. Make sure each table in the database has sufficient number of records such that each query results in a meaningful and reasonable size of output. What you need to do: a. Draw an E-R diagram for the CMS system b. Create appropriate tables corresponding to this diagram c. Create and populate the tables using MySQL. d. Answer the following queries in SQL and give the result for your data: Insert a new contract with ACV of $90,000, On-premises services, based in Montreal, with an initial amount of $10,000 given by "GSC Corporation". Insert details of a manager "Juan Vasquez" in the database, who is managing a team of 10 developers and responsible for "On-premises" projects. Provide a list of all managers supervising projects with more than $80,000 ACV. Give a list of all the employees who are working on contracts with ACV of at least 85,000$. List of all the contracts managed by "Juan Vasquez". What you should hand in: You should print and submit a report that includes the E/R model for your database design together with reasonable assumption(s) you made; script to create and populate the tables (SQL), this must include a list of all relational schemas/tables and attributes within each table with appropriate data types, identify the key attributes for each table, and show the relationships among the tables. You should hand in the printout of tuples/records in each table, the script for the SQL queries and the output of the queries. Note: Every document related to the project work must be printed and properly bounded with a cover page indicating your group ID, each member’s student ID and name (official names only, no nicknames).

Web based System: IMPORTANT SUBMISSION INFORMATION You are to provide a working URL for your web site. This may be via your own web server or free web hosting service. This URL must be live and available from the Canada/UK from the submission date for at least THREE MONTHS to allow for marking and verification of results. It is up to you to make sure that the URL is live. If the URL is not available for marking, you are very unlikely to pass the assignment, there are many organisations offering free web hosting services with appropriate facilities for things like PHP and mySQL. Search on “free web hosting”. Provide the .zip file containing your entire website to the student server for backup purposes. SCENARIO Handyman’s Hardware is a fictitious wholesale outlet that sells household hardware for home improvement including: hand tools, power tools, keys & locks, as well as plumbing & electrical supplies, etc. to retailers. They have asked you to design, implement, test and evaluate a website for them. The owners of the business do not have any web design knowledge at all but are generally familiar with standard office IT and with using the Internet for e-mail and web access. Because some of their competitors are very up to date with modern technology, and are deploying websites to attract additional customers, the company wants a modern website which makes use of leading edge design and technology in appropriate ways. They also expect their website to meet commonly published guidelines on usability and accessibility. Note: This business is fictitious but is representative of similar businesses throughout the world. On the Internet there are links to many websites that you can use as information sources, but not implementation, sources. Please DO NOT try to contact any business directly about this assignment. They are much more interested in running their business than student assignments. Functional Requirements As a minimum, your website must provide the following: 1) Operate as a “shop front” advertising the hardware products that they supply with the aim of increasing customer business. The website should include appropriate product details, some photographs and a “how to find us”. For the purposes of the “how to find us” section, use this address: 33 The Comp, Eaton Bray, Bedfordshire, LU6 2DH. This is a real address and will come up on web mapping sites and SatNav systems with UK maps. There is no hardware retailer there! 2) An “on-line shop allowing people to order anything that the company sells. This should allow the browsing of a catalogue of stock items and the use of a shopping basket and checkout facility. 3) A searchable database of appropriate products. 4) A customer sign up and login facility to enable regular customers to use the site more easily in that their customer details are stored securely. 5) Database maintenance facilities allowing company staff to add new stock items, delete stock items that are sold, correct and update information on stock items on the database and print a catalogue of stock items for distribution locally. This should be via a web interface with appropriate security on login. 6) An invoice for the customer based on what they have ordered, with totals including shipping costs. Note: You do NOT need to implement a payment system. Instead, put a “Pay Now” button in an appropriate place that when clicked will load a page saying: “Thank you for your payment”. Assignment Tasks You are to investigate and report on some currently available websites in this area (Task 1) and then design, develop, implement and deploy a web site for the company (Tasks 2 & 3). Task 1 (approx. 900 words) Write a report for company management team that critically evaluates the website examples given below: https://www.wickes.co.uk/ https://www.diy.com/ https://www.toolstation.com/ https://www.toolsdiy.co.uk/ Note: They are all real companies. Please DO NOT contact these, or any other, companies. They are commercial operations trying to make a living and will not be keen on enquiries from students trying to do assignments! Task 2 (approx. 1,000 words) Having evaluated the example websites above, identify appropriate technologies that could be used on a website in this area of business. Outline the technologies you have identified saying what they do, how they will benefit a business and any drawbacks they have. You do not need to cover basic technologies but should focus on novel or leading-edge technologies that could enhance the websites you have seen.

Its name doesn’t matter to Django; you can rename it to anything you like. manage.py: A command-line utility that lets you interact with this Django project in various ways.
