I contributed an article for EMC Proven Professional Knowledge Sharing 2008 entitled Real-Life Service-Oriented Architecture (SOA) with D6. It has now been published on EMC Education Services site. On the same topic, I also wrote an article on CMSWire.
For ease of access, the article is being made available here as well (with permission from EMC) – download article. The abstract of the article follows.
Service-Oriented Architecture (SOA) facilitates composition of loosely-coupled services into new services and applications. SOA must deliver business and technical agility to be successful. In other words, SOA serves business goals other than the standard “potential cost reduction via technical changes.”
This article translates a real-life business goal into an SOA solution that includes a key service provided by D6 (EMC Documentum version 6). While the article is primarily technical, it keeps business drivers and context at the forefront.
Even as SOA is becoming mainstream, Enterprise Content Management (ECM) has become a key piece of the enterprise infrastructure puzzle. Explosive content growth has led Gartner to forecast a 12% annual growth in ECM software revenues for the next three years. EMC Documentum has been a leading player in the ECM space so it should come as no surprise that SOA has been adopted as one of the core principles of D6.
D6 provides Documentum Foundation Services (DFS) for plugging Documentum into an SOA solution. Documentation and articles about D6 and SOA typically focus on DFS features. While they are essential for using Documentum in an SOA solution, they need another complementary capability for completing the SOA picture – orchestration of services for composing new services or applications. This article explores implementation of a real-life business scenario via an SOA solution including Documentum as a key component.
Consider a business goal to reduce Days Sales Outstanding (DSO) defined as the average collection period of account receivables over a time period (typically quarterly or yearly). A large DSO value means that it takes longer for the business to collect payments. A process analysis reveals that invoice presentment and payment are the primary improvement opportunities. This article describes an SOA-based implementation of an Invoice Presentment and Payment Application. Documentum is used to manage payment-related documents such as invoices and payment receipts.
The article illustrates the following key aspects of such a solution:
- Using DFS for creating content-oriented services
- Orchestrating SOA services for composing applications or other services
- Addressing real-life concerns
