  7. How Do We Handle This? Monolithic Server Distributed Database

  8. Monolithic Server • What is a monolithic server? - One single server for each primary business discipline MasterServer • Pros • - Simplified Domain Space • - Common Data Model / Common Process • - Lower system maintenance costs • Cons • - Cost of migration • - Loss of local control • - Slow to make changes to system Cost too prohibited to create a monolithic server.

  9. Distributed Databases • What is a distributed database? • - A collection of several different databases that looks like a single database to the user. • Pros • - Leverage existing investment • - Local control, enterprise visibility • Cons • - Complex to do data mapping • - Potential network latency issues What is the difference between Distributed Database vs Replication?

  10. System Requirements • Realtime • Manufacturing • Work in Process • Prototype Engineering Release Data Keep it simple. Prove the technology.

  11. Distributed Vaults • Start simple by combine homogeneous data in disparate systems Sudbury Tewksbury Optegra Optegra • Pros • - Distributed vault successful • - Each system has visibility into each system • - Both systems look like one • Cons • - Network Latency slows entire system performance- Slowdown makes system • unusable Network Latency creates too much downtime.

  12. Now What Do We Do? Data Warehouse

  13. Data Warehouse • What is a data warehouse? • “A data warehouse is a structured extensible data environment designed for the analysis of non-volatile data, logically and physically transformed from multiple source applications to align with business structure, updated and maintained for a long time period, expressed in simple business terms, and summarized for quick analysis.”

  16. Data Warehouse Initial Search Detailed Page Obtain an Account View Drawing

  17. Data Warehouse • Pros • - Leverage off of existing investment • - Inexpensive to stand up • - 6 months to build • - 8 hours to bring on new site • -Network Latency not as critical • Cons • - Cannot support real-time Delete and Update 31 million unique rows loaded nightly!

  18. Federation • What is Federation? • The linking together of information management systems for the purpose of distributed, collaborative, product development. • The creation and use of a heterogeneous network of data and processes where portions of the network are managed by different systems, yet the user sees a unified whole • What is a distributed database? • A collection of several different databases that looks like a single database to the user.

  19. Federation: Data Network • What is the definition of a Data Network? • A network consisting of associations between data in distributed systems • Associations can be built using three techniques: • Links • Proxies • Replicas

  20. Client request Client request Client redirect Cost A DB DB Cost A A Run time Generated Replica Master Proxy Link Cost A Federation by Link Corporate Systems Mfg Center Firewall Firewall Sourcing Report Inventory Windchill Server ERP Server Part A Cost A File Vault

  21. Federation by Link • Best use of links • When remote system has a Web-based UI and supports URL references to its objects and user is comfortable with switching between applications

  22. Select Part where Name = B Client request Display attributes Proxy B Return Part B attributes DB DB B A Run time Generated Part B Run time Replica Master Proxy Link B Federation by Proxy Design Center Design Collaborator Firewall Firewall Structure Browser Windchill Server PDM System Part A Part B File Vault

  23. Federation by Proxy • Best use of proxies • For consistent user interface to data residing in multiple systems • To be assured that you are looking at the latest up-to-date data • When data is loosely coupled, infrequently accessed • When you need to modify remote data without conflicts • For relating dissimilar data types residing in external systems • For composing data from multiple external systems (composite types) • When data is frequently accessed in a read-only mode

  24. Client request Client request Display part or stream content file Display part or stream content file Replicate Part B and Doc C Doc C Content replicated DB DB C B C B Doc C Replica Doc C C C A Run time Generated Replica Part B Replica Master Proxy Link Federation by Replica Design Center Supplier Firewall Firewall Structure Browser Structure Browser Windchill Server Windchill Server Part A Part B File Vault File Vault

  25. Federation by Replica • Best use of replication • For consistent user interface to data residing in multiple systems • To maximize end-user system performance • To overcome availability, security, restrictions

  26. Federation: Process Networks • Federated data is of limited use without having the business processes involving the Federated systems also being able to interact • Process networks should support: • Workflow interaction • Activity in local workflow, initiates a workflow in a remote system • Remote approval of activities • Change process interaction • Local change order initiates change activity in remote system • Federated task lists containing items from multiple systems • Event-based interaction • Each system both publishes events and responds to events in other systems (JMS, MQ Series, etc)

  27. Questions? How would a middleware vendor define Federation? How would an end solution provider define Federation? Any Questions?
