Q1.a) Based on the business rules, you are expected to construct
an Entity-Relationship (ER) diagram. The ER diagram should include
entities, attributes (if there are less than three specified in the
business statements, please add some extra attributes), identifiers
and corresponding data types, the relationships among entities with
cardinality and associative entities.
.b) Extend Q1.a) to apply generalization/specialization
technique to construct an Enhanced-ER (EER) diagram. The EER
diagram should specify the complete (total) and disjoint
(mutuallyexclusive) constraints on the
generalization/specialization....
A relationship is a connection between two tables of data based on one column in each....
A relationship is a connection between two tables of data based on one column in each. To see why relationships are useful, imagine that you track data for customer orders in your business. These relationships will be important as we try to bring data together to gain more insights into the work that we are trying accomplish. In your initial post, address the following: What do data types, data categorization, and data formation have to do with developing data relationships?...
