Component:

C_WissDB_DL_API

part of C_WissDB [?]

Abstract:

This component is the abstract DBMS used e.g. by C_WissDB_API to implement a B_Knowledge_Base.

Has to:

Own and manage

§      B_WissDB_Database.

Implement the following services:

§      S_Update_Process_Knowledge

§      S_Update_Aspect_Knowledge

§      S_Update_Result_Knowledge

§      S_Ensure_Association

§      S_Forget_Association

§      S_Set_Content

§      S_Get_Content

§      S_Get_Skeleton

§      S_Select_Results

§      S_Select_Items

§      S_Select_Processes

§      S_Exclude_Aspects

§      S_Exclude_Processes

§      S_Exclude_Results

§      S_Describe_DB_DomainValues

§      S_Replace_or_create_DB_DomainValues

§      S_Set_Alias

§      S_Get_Alias

§      S_Testsupport_New_DB

§      S_Testsupport_DL_API_Reaction_Scope

Make all these functions available via a well documented API that could be used by any kind of application.

Each of these functions must be protectable via C_Access_Control [?] as a separate resource (so that, depending on their role, users and applications might be restricted to use only some of these functions).

User Roles to be supported by C_WissDB_DL_API are

§      A_Application

§      A_Tester

Because of:

The Data Layer of WissDB should be reusable for applications similar but not identical to the Business Layer of WissDB.
