Question

You should use draw.io for this assignment. You are a database consultant for WidgetMart, Inc. You have been asked to design a database based on the following requirements. A supplier may supply many parts. Each part is supplied by any number of suppliers. Each part must be used in the assembly of at least one widget and may be used in many widgets. Each widget must use one or more parts. A supplier may send many shipments. However, exactly one supplier must send each shipment. A supplier may be able to supply a part, but may not yet have sent any shipments of that part. A shipment must include one (or more) parts. A customer may submit any number of orders. However, each order must be submitted by exactly one customer. An order must request one (or more) widgets. A given widget may not be requested on any order, or may be requested on one or more orders. Your submitted assignment should be an ER diagram showing all entities, attributes, primary keys, relationships, and cardinalities which would satisfy the above requirements. Be careful about extra information; remember you received these requirements from non-technical management.

Explanation / Answer

The pragmatic method turned into now not to desert the DES absolutely, but to exchange the manner wherein DES is used. This caused the modified schemes of Triple DES (every now and then referred to as 3DES).

incidentally, there are two variants of Triple DES called three-key Triple DES (3TDES) and a couple of-key Triple DES (2TDES)
