This is a generic scribble page used to log and discuss limitations to our current IT infrastructure. Currently, there is a focus limitations surrounding the IBM i and the ASW ERP software.

Data

Disaster Recovery

Query

Querying the server database for data is a core business function, providing the statistics to drive business development and financial decision-making. Transactional data is useless if there is no way to summarize and analyze it. In light of this, IBM has always packaged a query tool alongside the DB2 database that serves as the data heart of the IBM Power8 machine. This tool has evolved, and so has the query language, but we currently do not employ any of the newer and more efficient methods of accessing and reporting data (with the exception of Infonet).

  • First generation: Query/400 or AS/400 Query
  • Second generation: Query Manager for i
  • Third and current generation: DB2 Web Query for i

The RPG programming language

ASW and extensions are programmed in RPG.
