Explanation / Answer

1) A materials requisition is a requistion document prepared by the manufacturing or scheduling department, for
    requesting materials to be moved from storage to the factory floor so that production can start.
    Purchase requisitions is an internal document(s) used to request Purchasing department to procure a particular
    quantity of a material or a service for a particular date and either it can be created manually by the department
    responsible or automatically by MRP.
2) Because they represent a significant amount of product costs and the value added by the conversion process. In
    the revenue process, labor is typically insignificant when compared to inventory costs. The exception is if the
    revenue process involves the performance of services rather than the sale of goods, than in that case labor
   operations and labor types would usually be tracked.

3)
   a) The integrated view should include only one cash entity.
   b). The integrated model cash entity should include the attributes cash account id, cash account type, cash
         account number,cash account location, and cash account balance. This list of attributes represents a set
         union of the attributes from the separate cash entities indicated in the individual views.
   c). You must ask whether cash account id and cash account number are different (the list in part b assumes they
         are different – may be that the id is assigned by the enterprise and the account number is assigned by the
         bank) thereby resolving potential attribute name conflict. Similarly difference between cash account type and
         account type can be confirmed (as the list in part b assumes),if any .

4) Synonyms and homonyms. Synonyms share the meanings with other words.They have different labels (with equivalent meaning) used to represent the same entity. Homonyms words dound alike but have different meanings.A homonym have single label (with alternative meanings) used to represent different entities
