  22. 22. Prototypes <ul><li>An online financing application. </li></ul><ul><li>An online merchandise selling application. </li></ul><ul><li>An online office supply ordering system. </li></ul>

  27. 29. An online office supply ordering system <ul><li>Server DIAE Components </li></ul><ul><ul><li>Session management </li></ul></ul><ul><ul><ul><li>Authenticate user login. </li></ul></ul></ul><ul><ul><ul><li>Match session id to user credentials. </li></ul></ul></ul><ul><ul><ul><li>Determine valid session ids. </li></ul></ul></ul><ul><ul><li>Inventory Browser </li></ul></ul><ul><ul><ul><li>Provide a list of office supplies available upon valid request. </li></ul></ul></ul><ul><ul><ul><li>Filter the list of office supplies based upon search criteria. </li></ul></ul></ul><ul><ul><li>Cart Manager </li></ul></ul><ul><ul><ul><li>Record the item selections for a specific session. </li></ul></ul></ul><ul><ul><ul><li>At checkout, validate session selections against the session’s </li></ul></ul></ul><ul><ul><ul><li>user credentials. </li></ul></ul></ul><ul><ul><ul><li>At checkout, request office location where to ship the requested supplies. </li></ul></ul></ul><ul><ul><ul><li>Store the result of checkout in database. </li></ul></ul></ul><ul><ul><li>Relational Database server (provided as COT software) </li></ul></ul><ul><ul><ul><li>Store data for the other 3 DIAE server components. </li></ul></ul></ul>
  28. 30. Identifying the Domain
  29. 31. What is the domain? <ul><li>By now the domain should be relatively clear. </li></ul><ul><ul><li>Online, client server </li></ul></ul><ul><ul><li>Searchable inventory </li></ul></ul><ul><ul><li>Select items to receive </li></ul></ul><ul><ul><li>Selected items are validated based upon application specific logic. </li></ul></ul><ul><li>Remember the reference applications. </li></ul>
  30. 32. What is NOT in the domain? <ul><li>Obviously, things that do not meet the criteria previously described </li></ul><ul><ul><li>Video games </li></ul></ul><ul><ul><li>Word processors </li></ul></ul><ul><ul><li>Online message board </li></ul></ul>
  31. 33. More subtly… <ul><li>Real time vending services. </li></ul><ul><ul><li>For example: </li></ul></ul><ul><ul><ul><li>Medical supply retrieval. </li></ul></ul></ul><ul><ul><ul><li>Juke Box / DJ services </li></ul></ul></ul><ul><ul><li>Reasons: </li></ul></ul><ul><ul><ul><li>Service to fulfill requested order is not in architecture. </li></ul></ul></ul><ul><ul><ul><li>Real time delivery of order not guaranteed. </li></ul></ul></ul>
  32. 34. More subtly (con’t) … <ul><li>Inventory Management systems. </li></ul><ul><ul><li>For example: </li></ul></ul><ul><ul><ul><li>Stock management for retail store. </li></ul></ul></ul><ul><ul><ul><li>Factory inventory control. </li></ul></ul></ul><ul><ul><li>Reasons: </li></ul></ul><ul><ul><ul><li>Architecture is designed for browsing the inventory, not managing it. </li></ul></ul></ul><ul><ul><ul><li>Administrative interface is not well defined enough to provide enough reuse in these areas. </li></ul></ul></ul>
  33. 35. More subtly (con’t) … <ul><li>Free Text Data Repository / Knowledge Base </li></ul><ul><ul><li>For example: </li></ul></ul><ul><ul><ul><li>Internet search engine’s cache </li></ul></ul></ul><ul><ul><ul><li>MSDN help </li></ul></ul></ul><ul><ul><li>Reasons: </li></ul></ul><ul><ul><ul><li>Search of inventory is not optimized for free text searches. </li></ul></ul></ul><ul><ul><li>Some of these could be in the domain. </li></ul></ul><ul><ul><ul><li>Phone book – Structured data fits architecture. </li></ul></ul></ul>
  34. 36. Adding to the domain. <ul><li>Application domains close to, but not in, the domain can be added. </li></ul><ul><ul><li>The current architecture can be extended. </li></ul></ul><ul><ul><li>Will incur additional cost to the customer to properly integrate into the architecture. </li></ul></ul><ul><ul><ul><li>Architect and create new reuse assets </li></ul></ul></ul><ul><ul><ul><li>Low reuse on these applications </li></ul></ul></ul>
