(2) Exchange Workflow Designer
Microsoft's message platform solution provides Microsoft Exchange 2000 Server, using the latest "Web Storage" technology, providing features of browser access messages, as well as a message platform for knowledge management.
[Web Storage] Technology mainly stores the message data of Exchange 2000 Server's semi-structured database including mail, notes, logs, work, action calendar, contacts, 6 message functions, etc., integrated in Windows file system, including WEBDAV --- Web Distributed Authoring and versioning, full text retrieval, security permission function ﹞, simulate "Archive General Management" to manage these messages, via virtual directory, let information becomes web-based, 6 messages.
Microsoft Exchange 2000 Server built-in workflow management solutions are "Exchange Workflow Designer", using the Web Storage Attribute (Property) and XML to record all form information and process records, unused database, positioning as "software developers Application of (Non - information Manager) Design Workflow.
Why is Exchange Workflow Designer to "Software Developers" instead of information administrators? Because Exchange Workflow Designer only provides a process rule tool, "Write programs in each process" after pulling the process. " Others such as handling notifications, process tracking, agents, form production, statistical reports, integrating existing external database, applicant self-reservation process, previous executive derivative, organizational map, digital signature, batch processing, reputation, fast Processing, error record, etc. Of course, there is still more writer.
Specific references: This article introduces the development process in detail, which is designed in the Forms of Outlook, Exchange Workflow Designer Marketing Process Rules.

Use Exchange Workflow Designer software design process management applications, you must pay attention to solve the following questions:
1. Function of "Form, Process Change Version Control" is not provided: After the form, the process is changed, the data in the original process is complete (ie, the flow chart is changed, the information in all processes is not seen).
2. Functions that do not provide "Transaction": Unable to synchronize the process data and external database. The process updated the external database in the process. If the external database is busy, the process information will not automatically reply to the original state. Causes, such as approved the holiday process, the personnel please record the external database but not updated. This doesn't even do it even in LotusworkFlow.
3. The amount of accumulated amount is too slow: after the application is accumulated to hundreds of forms, the process notification, process tracking, and statistical analysis speed is very slow. This is because unused databases.
I recommend:
ASP.NET Write a web page, making a form, integrated application

Exchange is stored as a background, because it is a semi-structured database, many aspects without SQL Server 2000 so perfect, such as (backup), etc., look forward to Exchange 2003 postscript:
