This namespace contains the collection of objects that manage relational data in your application.

Description:

• This namespace contains the collection of objects that manage relational data in your application.

  A parasql.schema.TransactionSet is a collection of one or more related parasql.schema.DataTable objects. Each DataTable contains an array of parasql.schema.ColumnInfo objects that hold info about each column (e.g. its name, datatype, etc.) and an array of parasql.schema.DataRow objects that in turn have an array of parasql.schema.DataValue objects that contain the actual raw data values. If you make changes to multiple data values across multible tables within the same transaction set, all of the changes (including all inserts, updates, and deletes) can be saved within a single transaction by calling the parasql.schema.TransactionSet#save method.

  Note that if you change the value of a DataValue object that change will not become visible in the user interface of your application until you call parasql.widget.AbstractWidget#redisplay on the widget or one of its parents.
