Components of an Interface

The interfaces use the following components:

• Datastores defined in the models as sources and target of the loading process.
• Knowledge Modules to generate the appropriate processes.
• Variables and Sequence to store values or counters in the expressions.
• Users functions to ease the transformation rule coding.
   

  Flow and knowledge modules

  
  The flow is the set of loading and integration strategies for mapped data, based on knowledge modules as :
  

  • Loading strategy: Loading Knowledge Module (LKM)
  • Integration strategy: Integration Knowledge Module (IKM)
  • Control strategy: Check Knowledge Module (CKM). The flow control strategy lets you define the method used to check the flow before the insertion in the target.
