Database management

Database management is the process of storing, organizing, and accessing data on a website or web application. It involves using database management systems (DBMS) like MySQL, Oracle, and MongoDB to create and manage the data, and to enable users to access and manipulate it.

Database management is a crucial component of web development, as it enables a website or web application to store, retrieve, and use data in a structured and efficient manner. It should be scalable and reliable and should provide a secure and flexible platform for the data.

Here are some key aspects of database management that every website or web application should consider:

Data modelling

Data modelling is the process of designing the structure and relationships of the data on a website or web application. It involves defining the entities, attributes, and relationships of the data, and mapping them to the database tables, columns, and keys. To create good data modelling, database managers should have a strong understanding of the database concepts and principles and should be able to use appropriate tools and techniques.

SQL

SQL (Structured Query Language) is the standard language for accessing and manipulating data on a website or web application. It uses a system of commands and clauses to define and execute the queries, updates, and transactions on the database, and to enable users to retrieve, modify, and delete the data. To create good SQL, database managers should have a strong understanding of the SQL syntax and semantics and should be able to write, read, and debug SQL code.

Database design

Database design is the process of creating and implementing a database on a website or web application. It involves defining the tables, columns, keys, indexes, and constraints of the database, and mapping them to the data model and the requirements of the site or app. To create a good database design,
