Business logic lets users be sure that new critiques they are submitting apply to titles contained in the FmLib database. It works with Microsoft Exchange Server public folders in the following ways:
Using CDO, critique text in RTF format is retrieved from posted critiques in the Microsoft Exchange public folder for display on CML pages in HTML. See About the Critique COM Component.
The contents of the Microsoft Exchange public folder and the FmLib database should be kept synchronized. Folder events and triggers are used to accomplish this. When a change occurs in the LitCrit Exchange public folder, a folder event is generated, which triggers action by an agent of the Microsoft Exchange Server Event Service (see Using the Exchange Event Service and Updating SQL Server from the Exchange Information Store).
When the Critique table in the FmLib SQL Server database is changed, a trigger takes appropriate action. See Updating the Exchange Information Store from SQL Server.
