As the need for "right-time" information becomes more prevalent, organizations are looking to new information delivery methods such as Enterprise Information Integration (EII). It's more than a distributed query, but where do vendors over-promise and under-deliver? This presentation will explain EII, how it's different from other integration technologies, and the underlying mechanisms. The goal is to outline areas where EII is a good fit and areas where other tools may be more appropriate.
10. EII Architecture: Process-based EII View APIs xform Publish an ETL process as a service – the output of the process is the “view” Approach some ETL vendors have for on-demand access Back-to-front model Applications Databases XML/Services
11. EII Architecture: Model-based View is defined as a model over sources Most EII products work this way Front-to-back model Applications Databases XML/Services EII View APIs
12. How EII Works 1. User’s client sends a request which goes to the EII server interface Applications Databases XML/Services EII Server EII View SQL
13. How EII Works 2. The EII server parses the request and creates query fragments to send to the sources Applications Databases XML/Services EII Server EII View SQL
14. How EII Works 3. Each source system receives its query fragment, processes it and returns the result Applications Databases XML/Services EII Server SQL
15. How EII Works 4. EII server assembles the final result (which may mean additional processing) and the result is sent back to the client Applications Databases XML/Services EII Server EII View SQL
