30. #GPUGSummit | #INreno15 DECOUPLED BUSINESS LOGIC

31. #GPUGSummit | #INreno15 DECOUPLED BUSINESS LOGIC  Business Logic is provided by source other than a UI form. – Ex. sproc, other web service, pass thru sql, “PD” forms in the dictionary. Ex of PD form. Form\IV_Item  Should be faster than wrapped window. Encourages separation of business logic and presentation.  Might require a refactor if business logic currently resides in a form. – How do decide whether to refactor? Frequency of use and throughput should drive the decision.

32. #GPUGSummit | #INreno15 DECOUPLED BUSINESS LOGIC  No implicit datatype validation/conversion. – Map statement in wrapped window takes care of casing, signed vs unsigned precision and nulls. – In decoupled these things need to be coded. Examples for Decimals, Drop down lists and radio groups.

33. #GPUGSummit | #INreno15 DECOUPLED BUSINESS LOGIC  Check for valid sign and precision.  Check for valid value for a Drop Down or Radio Group.

34. #GPUGSummit | #INreno15 DECOUPLED BUSINESS LOGIC  Force strings to upper case as needed, for instance Item Number  Code must provide default values as needed in case the user passes a null value.  Demo create an Item.
