What is a Database?
A database is a collection of data that is arranged so that it can be accessed, managed, and updated easily. The most popular type of database is the relational database. It is the type of database that is frequently used in websites.
A relational database has the concept of tables, where data is stored in rows and columns, much like a spreadsheet. Each row in a table contains the complete information about an item that is stored in the table. Each column, on the other hand, contains information about a specific property of the rows in the table.
The term “relational” refers to the way the different tables in the database can be related to each other.It removes the duplication of data and stores the repeating data in its own table and then create a relationship to that data from other tables.
A web application needs a full relational database management system (RDBMS), such as SQL Server. The RDBMS handles the data infrastructure, ensuring optimum performance andreliability.RDBMS takes the responsibility of providing data to multiple users, disallowing invalid data, and using transactions to commit groups of actions at once.
You can use many different kinds of databases in your ASP.NET projects, including Microsoft Access, SQL Server, Oracle, SQLite, and MySQL. However, the most commonly used database in ASP.NET websites is probably Microsoft SQL Server.
