The CONNX for RMS module provides secure, real-time, read/write SQL access to RMS files on the VAX, Alpha and HP Integrity Servers running OpenVMS. In conjunction with other CONNX modules, you can perform seamless joins between RMS and most other databases.
With CONNX for RMS, 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 performs joins between multiple RMS files using a single SQL statement, otherwise impossible without custom development, and simplifies manipulation of large arrays through its unique Rotated Array Technology. The CONNX distributed SQL engine uses advanced index optimization to ensure maximum performance when retrieving data from RMS files.
The CONNX for RMS distributed SQL engine reduces the workload placed on the server by by performing CPU-intensive operations where the CONNX client resides (Unix, Linux or Windows. i.e., remote desktop, Web and/or application server), while allowing the database engine to perform tasks for which it is best suited. This distributed SQL engine facilitates truly scalable application development because of the additional processing power gained by the use of the client PC in addition to the database server.
CONNX for RMS directly imports RMS metadata from COBOL copybooks, Digital's common Data Dictionaries, DIBOL, VAX Basic File Description, Powerhouse PDLs and a CONNX Text Specification file format into a CONNX Data Dictionary file (CDD). Once, imported, the target RMS file can be treated as one or more logical tables or views.
