What is a relationset

From JACOBWiki

[edit] What is a „Relation Set" in the context of jACOB?

First of all jACOB is divided into three different layers.

A „Relation Set" is part of the „Logical Data Layer" and is a collection of relations between the logical data tables (table aliases).

Now we know the definition of a „Relation Set".
But what is the practical usage of a „Relation Set" in a jACOB application?

Let’s show an example.

1. Create „Relation Set" where one Organization has a lot of employess. (1:n)

2. Assign this „Relation Set" to a search button in an employee form.

3. Click the search button.

4. The search result will be displayed.

5. Click on a row to display the whole data record and its related data.

„Relation Sets" provide a powerful mechanism to define and handle complex relations between data tables without any line of code or SQL.
