This article looks at sets from an informational processing perspective; what they are; how they are constructed; and, distinct ways in which data can be drawn from sets within IRI software products using the SortCL data definition and processing program; i.e.,
Data and database migration are key considerations for any system implementation, upgrade, or consolidation. Data migration happens for many reasons, like appliance upgrades or enhancements, server maintenance, or data center relocation.
One of the best ways to speed up big data processing operations is to not process so much data in the first place; i.e. to eliminate unnecessary data ahead of time.
Data migration is done using NextForm; IRI’s data migration utility for converting large files into different formats and/or translating field-level data into other types. The current version converts between uniform XML and text files, LDIF and CSV, Vision and ISAM, MF COBOL variable-length files and Excel, etc.
ODBC, Open Database Connectivity, is an industry-standard application programming interface (API) for access to both relational and non-relational database management systems (DBMS). ODBC was first developed by the SQL Access Group (SAG) in 1992 in response to the need to access data stored in a variety of proprietary personal computer, minicomputer, and mainframe databases without having to know their proprietary interfaces.
