As a guide, a Tascus database in high-volume production use has an overall size of 11GB after 4 years.

The same example database has the following table usage:


In this database, the largest amount of space is taken up by the StepList_Draft (95,575 rows) and StepList_Released (12,675 rows) tables - these are the tables where the steps for each sequence are saved (1 row = 1 step in a production sequence).

Both of those tables also have large indexes - which are designed to improve query speed when loading steps in a sequence.


Create the following indexes on the database to improve query performance.
