Constraints are the rules that we can apply on the type of data in a table. That is, we can specify the limit on the type of data that can be stored in a particular column in a table using constraints. The available constraints in SQL are: NOT NULL: This constraint tells that we cannot store a null value in a column.A check constraint is a rule that identifies acceptable column values for data in a row within a SQL Server table. Check constraints help enforce domain integrity. Domain integrity defines the valid values for columns within a database table. A check constraint can validate the domain integrity of a single column or a number of columns.I thought it was a reference to how to label the constraints ( which AFAIK cannot be named or labeled , and can only be programmatically changed using their index using SketchObject.setDatum.

To allow various stabilities without enforcing them at the constraint level however, you may use stability-flags like @<stability> (e.g. @dev) to let Composer know that a given package can be installed in a different stability than your default minimum-stability setting.Validation Constraints Reference.
