System analysis should include several main aspects

1. [Answer]: The main tasks of system analysis include the following aspects: (1) System modeling The quality of the modeling process has an important impact on the efficiency of system analysis. Usually, four types of variables should be considered when forming a model: decision variables, environment variables, result variables and evaluation variables.

2. Determine the scope of the research object and define the system and environment. Set system goals, conduct system goal analysis, and establish an index system. Investigation, research and data collection are the basis for systematic analysis, and provide a basis for the formulation of system plans and the establishment of system models.

3. The main contents of the system analysis report include the following five aspects: overview of the system development project.Overview of the current system. Requirements system description. The logical scheme of the new system. System implementation plan.

The main content of system analysis (which 6 aspects)?

Determine the scope of the research object and define the system and environment. Set system goals, conduct system goal analysis, and establish an index system.Investigation, research and data collection are the basis for systematic analysis, and provide a basis for the formulation of system plans and the establishment of system models.

System analysis focuses on the perspective of the whole business process. The main contents are: whether the process of business and data is normal and reasonable; the relationship between data, business process and management functions; whether the reform of the original system management model and the realization of the new system management method are feasible, etc.

Content: Systematically explain the objects of research and the problems that need to be solved. Purpose: To determine the goal and explain the focus and scope of the problem. Content: Collect data Purpose: On the basis of systematic analysis, analyze the interrelationship between various factors through data, and seek feasible solutions to solve problems.

System analysis method'sSpecific steps include: qualifying questions, determining goals, investigating and researching to collect data, proposing alternatives and evaluation criteria, evaluating alternatives and proposing the most feasible plans. The so-called problem of qualifying problems is the gap between the actual situation and the planned goal or ideal state.

The operation of e-commerce website should include six specific aspects: website demand analysis and collation, channel content construction, website planning, product maintenance and improvement, effect data analysis, and departmental communication and coordination.

The main contents of the system feasibility analysis are: after market research, the feasibility analysis of the development of products should be analyzed.

Briefly describe the steps of system analysis. Briefly describe the content and common methods of the systematic survey.

The specific steps of the system analysis method include: qualifying problems, determining goals, investigating and collecting data, proposing alternatives and evaluation criteria, evaluating alternatives and proposing the most feasible solutions. Qualified problem The so-called problem is the gap between the actual situation and the planned goal or ideal state.

Investigate and analyze user needs in detail. On the basis of the preliminary investigation of the master plan, further collect, understand and analyze user needs, and investigate the relevant details of users; (2) Determine the preliminary logical model. The logical model only refers to the logically determined new system model, and does not involve specific physical implementations.

The specific steps of the systematic analysis method include: qualifying problems, determining goals, investigating and researching to collect data, proposing alternatives and evaluation criteria, evaluating alternatives and proposing the most feasible solutions.

The main contents of the system survey include: system boundaries and operating status. Organizational survey, management function survey, business process survey, data process survey, constraints and weak links.

The methods of systematic investigation usually include: (1) Interview The advantages of interview are flexibility, large amount of information, easy to establish a good cooperative relationship with users, and explore users' potential views and ideas. The main disadvantage is that it is easy for users to omit requirements when introducing the situation.

Method (1) First, investigate the organization, including understanding the departmental composition of the organization, the functions of each department, etc., and prepare for the analysis of the information process. (2) Then investigate the business activities of each department (3) Assist users to clarify various requirements for the new system, including information requirements, processing requirements, completeness and completeness requirements.

Chapter III Structured Analysis and Design Methods 3.3 System Analysis and Establishment of Logical Models

1. System analysis focuses on the analysis of the whole business process, mainly The content includes: whether the process of business and data is normal and reasonable; the relationship between data, business process and management functions; whether the reform of the original system management model and the realization of the new system management method are feasible, etc.

2. Determine the operation requirements of the system. Obtain the physical model of the current system. Abstract the logical model of the current system. Establish a logical model of the target system. Revise the development plan.

3. Outline of the software Design is also known as the overall structureThe main tasks of design are to establish the overall structure of the software system, design the data structure and database, write outline design documents, and review outline design documents.

4. The overall structure design of the system is to roughly design the overall structural form and available resources of the new system according to the requirements of system analysis and the actual situation of the organization, which is a macroscopic and overall design and planning.

5. Program design The main basis of program design is the HIPO diagram at the system design stage and the database structure and coding design. Programming methods At present, most of the programming methods are carried out according to structured methods, prototype methods and object-oriented methods.

6. Chapter II Software Engineering Methods and Tools. This chapter mainly introduces software engineering methods, including three methods: traditional methods, object-oriented methods, and formalized methods.It also led to the tool UML.
