Question 1 of 124
With regard to databases, what is normalization?
Answer

Suggested Answer

The suggested answer is B.

Normalization in the context of databases is the process of organizing data to minimize redundancy and improve data integrity. This involves structuring a database in a way that reduces data anomalies and ensures that dependencies are properly managed, leading to the refinement of relations among the data tables. Therefore, the correct answer is the process of organizing and refining relations.

Question 2 of 124
Which three pieces of information did E.F. Codd describe as necessary to retrieve a data value from a relational database?
Answer

Suggested Answer

The suggested answer is D.

To retrieve a data value from a relational database as described by E.F. Codd, the necessary pieces of information are the attribute (which specifies the type of data), the relation name (which specifies the table), and the primary key (which uniquely identifies the row). These components together allow for precise access to a specific data value within the database.

Question 3 of 124
What is a virtual table?
Answer

Suggested Answer

The suggested answer is A.

A virtual table is a relation created as the result of data manipulation; it exists only in computer memory, and is not a permanent part of the database. This definition captures the essence of what a virtual table, or a 'view', is in database terminology. Views temporarily represent the data stored in the actual tables but do not store data themselves in the database.

Question 4 of 124
Your enterprise has reached the conceptual design phase for a database project. What is the desired goal at the end of this design phase?
Answer

Suggested Answer

The suggested answer is B.

During the conceptual design phase of a database project, the primary goal is to produce a comprehensible and reviewed entity-relationship (ER) model. This model will represent the main entities, their relationships, and the primary constraints. It serves as a blueprint for the logical and physical designs that follow, ensuring the database captures all necessary details about the enterprise’s data requirements without focusing on implementation-specific details such as normalization or data redundancy elimination at this stage.

Question 5 of 124
In which phase of database design do you identify entities, attribute domains, and relationships?
Answer

Suggested Answer

The suggested answer is D.

The phase of database design where you identify entities, attribute domains, and relationships is the Conceptual phase. During this phase, the focus is on defining what the system contains. It involves creating a conceptual schema that outlines the structure of the data, independent of how it will be physically implemented. This includes identifying the entities, their attributes, and the relationships between the entities.
