Types of Databases

There are many different types of databases, each with its own strengths and weaknesses. Some of the most common types include:
Relational databases: Relational databases store data in tables, which are made up of rows and columns. Each row represents a single record, and each column represents a field or attribute of that record.
NoSQL databases: NoSQL databases are a newer type of database that is designed to handle large amounts of unstructured data. NoSQL databases do not use tables, and they can store data in a variety of formats, including JSON, XML, and key-value pairs.
Object-oriented databases: Object-oriented databases store data in objects. Objects are self-contained units that contain both data and methods. Object-oriented databases are often used to store complex data, such as images, videos, and documents.

Components of a Database

A database is made up of several different components, including:
Data: The data is the most important part of a database. It is the information that you want to store and retrieve.
Database schema: The database schema defines the structure of the database. It specifies the tables, columns, and relationships between them.
Database engine: The database engine is the software that manages the database. It handles tasks such as data storage, retrieval, and indexing.
Database users: Database users are the people who use the database. They can create, update, and retrieve data from the database.

Database Operations

There are many different operations that can be performed on a database, including:
Create: Creates a new database or table.
Insert: Inserts new data into a table.
Update: Updates existing data in a table.
Delete: Deletes data from a table.
Query: Retrieves data from a table.
