A programming language that supports relational databases is SQL (Structured Query Language)
Structured Query Language (SQL), is the principal method for communicating with Relational Databases.
A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.
- Tables are utilized for storing data about the items that will be displayed in the database.
- A column in a database contains a specific type of data, whereas a field records the actual value of an attribute.
- The table's rows indicate a collection of linked values for a single item or entity.
Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.
