Answer and Explanation:

A strictly layered pattern can be defined as an approach that restricts the interaction of the components in a layer in the application.

It limits the interaction of the layer components to the adjacent layers or the layer that lies just below the the layer itself.

For Example:

If the application is layered as the Fig 1. shows

Then accordingly, Layer K will interact with the layer K - 1 and Layer K - 1 will interact only with the layer K - 2 and so on.

Consider what fact-finding techniques you would use to identify the important facts needed to develop a database system. Please

8090 [49]

Answer:

Examples of Fact-finding techniques includes:

Prototyping
Questionnaires
Research and sites visit
Interviews

Explanation:

It is important to note that a database system is a tool that allows users to define, create, maintain, and control access to a collection of logically related data and description of these data, designed to meet the information needs of an organization.

Prototyping

Advantage: enables testing and understanding of the system in advance before final implementation of solution, while requiring less time for research.

Disadvantage: Training and Development cost consumes resources.

Research and site visit

Advantage : better time management if the problem has been researched upon before.

Disadvantage: appropriate permission is often needed before using research materials.

Questionnaires

Advantage: This technique is not expensive, and responses can be calculated and analysed quickly.

Disadvantage: There may be Incomplete answers received from users and body language of user cannot be observed.

Interviews

Advantage: The body language of interviewees is been perceived.

 Disadvantage: Interviewing is time consuming and costly.

Explanation:

The purpose behind to explore an integrated development environment is to learn more about the features of the environment.

So the correct answer is B.

For example, you can use visual studio to build asp.net application using c#, then you need to explore what features visual studio offering to you.

However, other options are incorrect. Because, you can learn more about syntax, error handling, and abstraction in the programming language, not in the IDE.

tensa zangetsu [6.8K]

Answer:

False

Explanation:

Note, the Rapid Application Development (RAD) software development approaches are noteworthy not for its expanded design details but for its simplicity of the software development process.

In other words, the RAD approaches while taking user preferences into the software development process, focuses on making the software design process more flexible, such as by employing the use of prototypes, and less unnecessary details.
