What is Database
The database is a collection of data which is used to retrieve, insert and delete the data efficiently and each data is related logically to each other to fulfil some need like data of student, Employee, Vehicle.Each Record or data of student or employee is also well - organized in the form of a table, schema, views, and reports, etc. Database management system (DBMS) is software that is used to store, manage, retrieve the database.Our DBMS Expert will help you in all topics of DBMS such as introduction, ER model, keys, relational model, join operation, SQL, functional dependency, transaction, concurrency control, etc. For example: The College database stores the data about the admin, staff, students and faculty etc. so that with help of the database easily can retrieve, insert, and delete the information.
Characteristics of DBMS
Provide a clear and logical view of the process the data.
Structures and described data
Stores any kind of data
Support ACID (Accuracy, Completeness, Isolation, and Durability) properties
Backup and recovery
Concurrent use of database
Reduce the complex relationship between data.
View the database from different viewpoints according to the requirements of the user.
Some of the key concepts of database management system includes given below:
Adding data to your database
Querying a database

What are the types of databases we provide help?
A relational database is a type of database that stores and provides access to data in the form tables. Table is also referred as Relation. Tables consist of rows and columns. each row in the table is a record with a unique ID called the key. The columns of the table hold attributes of the data, and each record usually has a value for each attribute, making it easy to establish the relationships among data points.
A relational database example
A simple example of two tables, customer info and orders. The first table is a customer info table, so each record includes a customer’s name, address, shipping and billing information, phone number, and other contact information. Each attribute is in its own column. In the second table—a customer order table—each record includes the ID of the customer that placed the order, the product ordered, the quantity, the selected size and color, and so on.
Microsoft SQL Server, Oracle Database, MySQL, PostgreSQL and IBM Db2 are DBMS for relational database
NoSQL databases are non tabular, and store data differently than relational tables. NoSQL databases come in a variety of types based on their data model. There are four major types of NoSQL databases emerged: document databases, key-value databases, wide-column stores, and graph databases. The simplest type to describe is the document database, in which it would be natural to combine both the basic information and the customer information in one JSON document. In this case, each of the SQL column attributes would be fields and the details of a customer’s record would be the data values associated with each field.
For example: Last_name: "Jones", First_name: "Mary", Middle_initial: "S", etc.
MongoDB, Apache Cassandra,CouchDB, and CouchBase are NoSQL databases.
A cloud database refers to any database that’s designed to run in the cloud. Like other cloud-based applications, cloud databases offer flexibility and scalability, along with high availability. Cloud databases are also often low-maintenance, since many are offered via a SaaS model. Examples: Microsoft Azure SQL Database, Amazon Relational Database Service, Oracle Autonomous Database
Most common database topics request by user for help.
Basics of DBMS
Joins and Keys
DDL, DCL, and DML
Indexing, B and B+ trees
Thread locks and types of locks
Transactions and Concurrency Control
Get help in database design
Database designing is to convert business requirement or conceptual idea into well defined model that can be used as information. The output of a database design is a data model. A data model represents all the objects, entities, attributes, relationships, and constraints in the system. Data models can be of two types: logical or physical. The representation of the data model is done by creating an ER diagram, also known as an entity relationship diagram, an ERD diagram, or a database diagram.
Steps in database design:
Determine the purpose of your database
Find and organize the information required
Divide the information into tables
Turn information items into columns
Specify primary keys
Set up the table relationships
Refine your design
Apply the normalization rules
Our database expert will provide help in every step on database design so that you can get better understanding of database design process.
Get Help in ERD (Entity Relationship Diagram)
An entity relationship diagram (ERD) depicts the relationships of entity set in a database. An entity in this context is an object, a component of data. An entity set is a collection of similar entities. These entities can have attributes that define its properties. By defining the entities, their attributes, and showing the relationships between them, an ER diagram illustrates the logical structure of databases.
Our database team of expert use the following Database Diagram (ERD) Design Tools draw.io, dbdiagram.io, Lucidchart, SQLDBM, QuickDBD etc.
Get Help In Database Schema Diagram
A database schema is the blueprints of your database. Database schema design organizes the data into separate entities, determines how to create relationships between organized entities, and how to apply the constraints on the data. if you are stuck in database schema diagram our database assignment help expert will help you.

Get Help In Database normalization
Database normalization process help to identify if your tables are structured correctly and database schema design technique, by which an existing schema is modified to minimize redundancy and dependency of data. It divided into different categories: 1NF, 2NF, 3NF, BCNF, 4NF, 5NF. The idea is to help you ensure that you have divided your information items into the appropriate tables. What normalization cannot do is ensure that you have all the correct data items to begin with.You apply the normalization rules in succession, at each step ensuring that your design arrives at one of what is known as the "normal forms." Five normal forms are widely accepted — the first normal form through the fifth normal form. This article expands on the first three, because they are all that is required for the majority of database designs.

Get Help In Database Query
Database query is used to perform operation on databases like retrieve, insert, update, delete etc.A database query is a request to access data from a database to manipulate it or retrieve it. Structured Query Language (SQL) is the most famous of the query languages. It serves the basis of relational databases. With SQL, we can store, retrieve, and manipulate data using simple code snippets, called queries, in an RDBMS (relational database management system).
There are five types of SQL commands: DDL, DML, DCL, TCL, and DQL.

Why Database is so Important?
Database 's a collection of organized data on a system that can be accessed, updated, managed easily by computer program.Storing data means managing so that we can access data fastly and efficiently. By using a DBMS,It's a software where we store data ,is more accessible and integrated with the rest of our work. We need some way to collect, store, retrieve, sort, graph, and manipulate the data of the world. Databases allow us to do this. Without them we would be unable to do many of the things we can do today. So we need a database systems to store and operate data.
Functional Dependencies: A functional dependency is a constraint between two sets of attributes in a relation from a database. In other words, a functional dependency is a constraint between two keys.
Transactions and Concurrency Control: A transaction is a logical piece of work of any database, which may be a complete program, a fraction of a program, or a single command (like the: SQL command INSERT or UPDATE) that may involve any number of processes on the database.
Join in Database: A JOIN clause is used to combine rows from two or more tables, based on a related column between them.
Databases use different types of join:
(INNER) JOIN: Returns records that have matching values in both tables
LEFT (OUTER) JOIN: Returns all records from the left table, and the matched records from the right table
RIGHT (OUTER) JOIN: Returns all records from the right table, and the matched records from the left table
FULL (OUTER) JOIN: Returns all records when there is a match in either left or right table
Relational Model: Relational Model represents how data is stored in Relational Databases. A relational database stores data in the form of relations (tables). Relational Model was proposed by E.F. Codd to model data in the form of relations or tables.
