Answer 1

Answers:

Both the systems analysis and systems designs will take place in the SDLC lifecycle

1.System Analysis:

The system analysis phase tells us about who are the persons going to use the system and what is the main purpose of the system what are the functions of the system and also the system analysis phase tells about where and when will be the particular system will be used after it completed its development phase.

In the system, the analysis phase has 3 steps

1.An analytical step

2.Requirement gathering step

3.The analyses

An analytical phase is mainly concentrated to made to show the path to the projects team's efforts . It includes details about the current system and the problems it is facing at present. By considering the present system it will show a path to design the new system/

Requirement gathering this step includes getting the necessary requirements to complete the project through interviews,workshops and questionnaires. This analysis of information consists of offers from project sponsors and many other people working under that project. Then the system will have knowledge about how the work will operate after the system was developed. It mostly includes models that show the data and process necessary to support the required business process.

Analyses finally the analyses , concept of the system and the output models are combined into a defined document called as the system proposal which is given to project sponsors and the other people whose decision is mandatory to go forward with the project or to exit the project. Most of the strategic decisions made her in this face

2.System designs:

This is the crucial part which decides and takes the decision how the system will going to operate or work in the terms of hardware, or in terms of software and it also includes about the network infra user interface, reports databases and the files which are required. This phase exactly decide of the system will operate

it has four steps

1. Design strategy should be determined. This step gives a clarification to the developers that whether it should be developed from their own company or whether to develop it form outsourced or if they could by any existing software package which satisfies their minimal requirements.

2. Here in this step leads to the development of the basic architectural design that describes the hardware of the system software of the system network databases everything related to its working

3. in this step that database related and the file specifications are developed. This mostly tells about where the data will be stored and what kind of data is stored

4. And finally, the analytical working team develops the software design which tell the programs that need to be code and accurately what each program or module of the software will do.
