Database Customisation
ESdat is designed to work closely with the underlying database in the management and manipulation of your data. Competant users may add additional tables, or write additional queries. This can be achieved by directly opening the underlying database using the Access link (or Management Studio for SQL Server databases).
So long as the queries in the Database run without errors they can be used through ESdat. This means the database is transparent to users and outputs can be customised to almost any extent.
