Data Service Message Library

The Data Service Message library contains classes for utilizing Request XML messages and Result XML messages.

The Data Service Client Library (LJCDBCLientLib) and the Data Service library (LJCDBServiceLib) use the Request and Result XML messages to communicate between them.

The DbRequest Object Graph
The DbRequest object is the top-level of an object hierarchy to serialize and deserialize the Request XML Message.
It uses the objects: DbRequest, Columns(DbColumns), KeyColumns(DbColumns), Joins(DbJoins), DbJoin, JoinOns(DbJoinOns), DbJoinOn, Filters(DbFilters), DbFilter, (ConditionSet)DbConditionSet, (Conditions)DbConditions and DbCondition.

The DbResult Object Graph
The DbResult object is the top-level of an object hierarchy to serialize and deserialize the Result XML Message.
It uses the objects: DbResult and DbRecords.
