This presentation looks at what FOCUS is doing under the covers when a TABLE command is executed in FOCUS on any platform, or through WEBFOCUS. Also, the TABLE command could be against a FOCUS file, DB2 TABLE, VSAM, etc. Application developers can create more efficient requests when they understand how FOCUS sets up to retrieve data from FOCUS files, Relational TABLEs, and other non-FOCUS data sources. Learn the answers to such questions as: When would an index be more efficient? One pass or two? DEFINE vs. COMPUTE? What is AUTOPATH and AUTOINDEX, and what do they mean in terms of efficiency?
