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

8. Monolithic Server What is a monolithic server? 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. Master Server - One single server for each primary business discipline

9. What is a distributed database? Distributed Databases 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? - A collection of several different databases that looks like a single database to the user.

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

11. Distributed Vaults Optegra Start simple by combine homogeneous data in disparate systems 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. 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.”

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

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 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

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 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

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