ISBL

ISBL stands for Information Systems Base Language. It was a special way of talking to computers that was made for PRTV. PRTV was one of the first systems to use a smart idea about organizing information, called the relational model. This idea was created by a person named E.F. Codd. ISBL helped people tell the computer how to find and change information in these early databases, making it easier to handle lots of data.

Example

The example shows how to find information from a database. It connects two pieces of data, called "ORDERS" and "SUPPLIERS". The goal is to look for something named "Brooks" and then show details like the item name and price.
