Question 1

The Performance Analyzer lists three kinds of analysis results: recommendations,suggestions,and ideas.

Accepted Answer

The Performance Analyzer lists three kinds of analysis results: recommendations, suggestions, and ideas.

Question 2

The Database Splitter tool enables you to split a database into three files: a back-end,middle,and front-end database.

Accepted Answer

The Database Splitter tool typically splits a database into two parts: a back-end database that contains the data tables, and a front-end database that contains the application logic, queries, forms, and reports.

Question 3

Normalization rules indicate the current state of a table.

Accepted Answer

The answer of Normalization rules indicate the current state of...

Question 4

The Database Documenter creates a report that contains detailed information about the tables and other selected objects in your database.

Accepted Answer

The Database Documenter is a tool in Microsoft Access that generates a detailed report containing information about the tables and selected objects in a database.

Question 5

The Performance Analyzer evaluates a database and makes recommendations for optimizing the database.

Accepted Answer

The Performance Analyzer is a tool that analyzes the database and provides recommendations for improving performance.

Question 6

Table Analyzer can create additional tables in your database.

Accepted Answer

Table Analyzer can create tables based on the analysis of your existing data, which can be useful in improving database efficiency and organization.

Question 7

Functional dependency occurs when the value of one field is determined by the value of another.

Accepted Answer

This is the definition of a functional dependency.

Question 8

The Performance Analyzer Tool creates a report that contains detailed information for each selected object.

Accepted Answer

The answer of The Performance Analyzer Tool creates a report...

Question 9

A conversion to a 3NF removes dependencies on part of a composite primary key.

Accepted Answer

The answer of A conversion to a 3NF removes dependencies...

Question 10

The Database Documenter saves its report in a number of formats including PDF or XPS formats.

Accepted Answer

The Database Documenter can save its report in PDF or XPS formats among others.

Question 11

The Database Splitter tool enables you to split a database into two files,a back-end and front-end database.

Accepted Answer

The Database Splitter tool in Microsoft Access allows you to split a database into separate front-end and back-end files. This helps improve performance and allows multiple users to share the data.

Question 12

A composite key is a primary key that is made up of one field.

Accepted Answer

A composite key is made up of multiple fields, not just one.

Question 13

The main reason to split an Access database is to improve development and maintenance.

Accepted Answer

Splitting an Access database separates the data (backend) from the user interface (frontend), making it easier to develop and maintain both components separately. It also allows multiple users to access the same data simultaneously.

Question 14

Multivalued fields are created using the Input Mask Wizard.

Accepted Answer

Multivalued fields are not created using the Input Mask Wizard. They are created by selecting the "Yes (multiple values allowed)" option in the field's Properties.

Question 15

The Table Analyzer analyzes the database and normalizes it for you.

Accepted Answer

The Table Analyzer does not normalize the database for you. It is a tool that helps identify potential issues and provides suggestions for improving the design and efficiency of tables in the database.

Question 16

First normal form is a table that contains no repeating groups or repeating columns.

Accepted Answer

First normal form (1NF) requires that each table column should be atomic, meaning it cannot contain repeating groups or multiple values in a single cell. This helps to avoid data redundancy and improve data integrity.

Question 17

One reason why you may not be able to create a relationship is because there may be an issue with the way you have normalized the database.

Accepted Answer

Normalization is an important concept in database design that helps ensure data accuracy and prevent redundancies, anomalies, and inconsistencies. If the database is not properly normalized, it may lead to difficulties in creating relationships between tables and performing queries.

Question 18

After the Performance Analyzer lists its analysis results,Access can perform recommendations and suggestions automatically,but idea optimizations must be performed manually.

Accepted Answer

While Access can offer recommendations and suggestions, the actual optimization changes must be made manually by the user.

Question 19

Optimizing a database may affect the database in ways you might not consider as positive results.

Accepted Answer

While optimizing a database can improve performance and efficiency, it can also lead to unintended consequences such as data loss, downtime, or unexpected changes in application behavior. It is important to carefully plan and test any database optimizations before implementing them in a production environment.

Question 20

Transitive dependencies exist in third normal forms.

Accepted Answer

The answer of Transitive dependencies exist in third normal forms....
