Enterprise information integration (EII) is the ability to support a unified view of data and information for an entire organization. In a
Overview
Standardized data access
.There are also standard formats for representing data within a file that are very important to information integration. The best-known of these is XML, which has emerged as a standard universal representation format. There are also more specific XML "grammars" defined for specific types of data such as
Enterprise Information Integration (EII) applies data integration commercially. Despite the theoretical problems described above, the private sector shows more concern with the problems of data integration as a viable product.[1] EII emphasizes neither on correctness nor tractability, but speed and simplicity.
- Combining disparate data sets
- Each data source is disparate and as such is not designed to support EII. Therefore, data virtualization as well as data federation depends upon accidental data commonality to support combining data and information from disparate data sets. Because of this lack of data value commonality across data sources, the return set may be inaccurate, incomplete, and impossible to validate.
- One solution is to recast disparate databases to integrate these databases without the need for ETL. The recast databases support commonality constraints where referential integrity may be enforced between databases. The recast databases provide designed data access paths with data value commonality across databases.
- Simplicity of deployment
- Even if recognized as a solution to a problem, EII as of 2009[update] currently takes time to apply and offers complexities in deployment. Proposed schema-less solutions include "Lean Middleware".[2]
- Handling higher-order information
- Analysts experience difficulty—even with a functioning information integration system—in determining whether the sources in the database will satisfy a given application. Answering these kinds of questions about a set of repositories requires semantic information like metadata and/or ontologies.
Applications
EII products enable
Data access technologies
- Service Data Objects (SDO) for Java, C++ and .Net clients and any type of data source
- XQuery and XQuery API for Java
