iWay Software's Intelligent Adapter for VSAM – XML, SQL, JDBC, and ODBC-Based Enterprise Integration
Accelerating VSAM Integration
iWay Software's intelligent VSAM adapter provides highly efficient access to VSAM data. The adapter is engineered in the same way as other iWay data adapters, so developers may use ANSI-standard SQL statements to access VSAM data from any iWay tool. Third-party products can also access the adapter via iWay connectors, including ODBC, OLE DB, JDBC, XML, iWay Business Services (Web services), and others. In addition, data may be integrated with more than 200 other information sources, including other relational and nonrelational databases, transaction systems, custom or packaged applications, message-oriented middleware, XML documents, EDI networks, and more.
How iWay Intelligent Data Adapters Work Together
All iWay Intelligent Adapters are designed for consistent operation within iWay's robust middleware framework, thereby minimizing the skill sets required to use each database and support new projects. Each adapter consists of a communications interface, an SQL translator that manages adapter operations in either SQL or iWay's universal Data Manipulation Language (DML), and a database interface that translates ANSI SQL into native API calls. Multiple iWay adapters running on the same platform can all share communications and translation components for greater efficiency.
Highly Optimized for VSAM
The iWay Intelligent Adapter for VSAM receives ANSI-standard SQL requests and translates them into iWay's universal DML. These DML statements are used to access the target database using native access methods to retrieve data targeted in the request. If required, the adapter will generate the appropriate iWay SQL and DML statements to perform cross-database joins with other data sources.
Special features and settings for iWay's VSAM Adapter include:
- Read/write capability
- Support for most commonly used data types, including character and packed data
- Key-sequenced data sets (KSDS)
- Entry-sequenced data sets (ESDS)
- Relative record data sets (RRDS) via private access modules
- COBOL group field support
- Access to positionally related and unrelated records via RECTYPE attribute
- Access to repeating groups via the RECTYPE attribute
- Use of alternate indices
- Variable and fixed-record length support
- Dynamic and re-entrant user exit support
- User-coded data access module support
- Re-entrant compression exit support
Special iWay Performance Features
The iWay adapter directly provides query control via the RECORDLIMIT feature to reduce communication traffic, CPU usage, and I/O activity. iWay's Resource Analyzer and Resource Governor products may also be used to analyze and control resources on a global basis independently of the adapter being used.
