CONNX for Ingres
The CONNX for Ingres module provides secure, real-time, read/write access to Ingres enabling it to be integrated with other CONNX supported enterprise data sources. Ingres is a relational and open-source database whiched was the basis for many other databases, like SQL Server, Sybase, Postgres, and PostgreSQL. In conjunction with other CONNX modules, you can perform seamless joins between two or more supported, disparate data sources.
With CONNX, a single metadata model can be created that spans all enterprise data sources and applications requiring data access. The result is an enterprise-wide view of data that provides a reusable, standards-based framework for information access.
CONNX supports the creation of views, which facilitates hiding table relationships from the end user. CONNX views facilitates the creation of heterogeneous joins between multiple disparate databases.
