Discussion of the link between the four information system functions, as well as the creation of a graphic to depict the relationship

The overall emphasis of the __________ phase is on gathering data on the existing system, determining the requirements of the new system, considering alternatives within identified constraints, and investigating the feasibility of alternative solutions. a. investigation b. analysis c. design d. construction

A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.

Data modelling is most often accomplished through the use of a(an) ________________. a. entity-relationship diagram b. data-flow diagram c. functional decomposition diagram d. activity diagram
