This section describes how to use the view builder to create views of your database that end users can access for reporting purposes. These views are built by first creating an entity relationship diagram which joins all required tables together.

By using the Yellowfin view builder you can optimise the SQL that will be generated by the query. For example if you create a view where multiple tables are joined - – Yellowfin will only select data from the tables necessary to return data required for the report. This means that you can create relatively complex views without compromising on performance.

...

You build your relationship diagram on the canvas by selecting tables from the source database using table list. You create joins to link the tables. When you have built the relationship diagram for your view, you can test the view using integrity and impact analysis checks.
