create the Block Diagram of the Information Technology solution

Assignment : Use case study to create a logical Block DIagram model of the new MIS system. To do this, apply the "Block Diagram" technology.  

  As you know, there are four main components of a Block Diagram: the entity itself; data associated with the entity; processes associated with the entity (only applies to people not documents); relationships between entities. Consider each of these areas as you create the Block Diagram of the Information Technology solution. Try, if you can, to keep your diagram to one side of one printable page.
