What kind of representation does a transaction identifier normally have in a dimensional model?

Explain in detail the meaning of the terms "aggregation" and "generalisation" as they relate to two different kinds of connections in a UML class diagram.

Consider the following E/R diagram with isa relationships, in which every node represents an entity set. If we follow an object-oriented approach and convert this hierarchy into relations/classes, the number of relations generated will be Isa Isa Isa

Draw an ER diagram for the EMU Slimming Center based on the specification given below. Case Study 01 A wedding hall (Shadi Hall) organizes different types of functions for its customers. Each function is hosted (owned) by exactly one customer. A customer may host many functions. There are many employees working at the company. Before each function date, the administrations of the wedding hall calls a meeting of relevant employees to finalize the arrangements of the function. Each meeting belongs to exactly one function. Comments/suggestions of each employee in the meetings and the decisions of the meetings are also recorded. Instructions: • Identify the relationship between Entities (clearly showing the cardinality and participation)

In a dimensional model, a transaction identifier looks like what?

Explain the concept of object graph serialization and its role in handling complex data structures.

Clearly define the meaning of two types of relationships in the context of a UML class diagram: aggregation and generalisation, and provide examples.

What is the difference between a weak and a strong entity set?

There are certain constraints imposed by selection structures in computer programming, notwithstanding their use. The same procedure must be followed in all cases, whether dealing with consumers, online clients, or other sorts of transactions. Is it true that various criteria apply to various occupations? So, why are these structures so special?     There are certain constraints imposed by selection structures in computer programming, notwithstanding their use.
