Before you customize row filters, it is important to understand the database architecture used by Ultrasound. The following table describes the components of the database and whether those components can be customized.
|Database schema||The collection of tables that contain data in the database. A table is a two-dimensional object, consisting of rows and columns, used to store data in a relational database.||No|
|View||An alternate way of looking at data from one or more tables in the database. A view can be thought of as either a virtual table or a stored query. The data accessible through a view is not stored in the database as a distinct object.||Yes|
|Row Filter||A set of criteria applied to records to show a subset of the records. (This is the WHERE clause of a SQL query)||Yes|
