Relational databases are designed to take care of all these problems. What’s more, things start to get messy when you want to link records together, such as linking a customer record to the orders that the customer has made, and then linking each order record to the products that are in the order. Searching and updating a very large text file is slow and prone to corruption. Here’s an example of a CSV this technique is fine for simple data structures and small amounts of data, you quickly run into problems as your site grows. If you haven’t used a database for your website before, you may have stored data in text files such as comma-separated value (CSV) files. Web scripts (right) communicate with the DBMS in order to insert, update, delete and retrieve data in the database. The following diagram shows how a database, the DBMS, and your website’s code interact with each other.Ī database (left) is a collection of related data, managed by a DBMS such as MySQL (centre).

Consequently, MySQL is known as a relational database management system, or RDBMS. One of the most popular is the relational model, which is what MySQL uses (along with PostgreSQL, Oracle, Microsoft SQL Server, and other common systems). There are many different ways to organize data in a database, known as database models.
