UNIT – III ANALYSIS, DESIGN CONCEPTS AND PRINCIPLES

1. List the guidelines for data design.

i. Apply systematic analysis on data.

ii. Identify data structures and related operations.

iii. Establish data dictionary.

iv. Use information hiding in the design of data structure.

v. Apply a library of useful data structures and operations.

2. Name the commonly used architectural styles.

i. Data centered architecture.

ii. Data flow architecture.

iii. Call and return architecture.

iv. Object-oriented architecture.

v. Layered architecture.

3. What is Transform mapping?

            The transform mapping is a set of design steps applied on the DFD in order to map the transformed flow characteristics into specific architectural style.

4. What is a Real time system?

Real time system is a software system in which the correct functionalities  of the system are dependent upon results produced by the system and the time at which these results are produced.

5. What are the objectives of Analysis modeling?

i. To describe what the customer requires.                                                     

ii. To establish a basis for the creation of software design.  

iii. To devise a set of valid requirements after which the software can be built.

6. What is an Architectural design?

            The architectural design defines the relationship between major structural elements of the software, the “design patterns” that can be used to achieve the requirements that have been defined for the system.

7. What is data design?

            The data design transforms the information domain model created during analysis into the data structures that will be required to implement the software.

           

8. What is interface design?

            The interface design describes how the software communicates within itself, with systems that interoperate with it, and with humans who use it.

9. What is component level design?

            The component level design transforms structural elements of the software architecture into a procedural description of software components.

10. What is software design?

            Software design is an iterative process through which the requirements are translated into a “blueprint” for constructing the software.

11. What is user interface design?

            User interface design creates an effective communication medium between a human and a computer.

12. What is system design?

            System design process involves deciding which system capabilities are to be implemented in software and which in hardware.

           

13. What are data acquisition systems?

            Systems that collect data from sensors for subsequent processing and analysis are termed as data acquisition systems. Data collection processes and processing processes may have different periods and deadlines.
