Graduation design (thesis) topic: bicycle parts management system
feasibility analysis
Feasibility, that is, whether it is necessary and necessary to develop this information system under the current situation, including necessity and rationality. The purpose of system feasibility analysis is to develop a management information system, whether it has the internal and external necessary conditions for its development, including technical, financial, economic, human resources and organizational management conditions, and also to analyze whether it is necessary to develop such an information management system under the current conditions.
The computer management level of bicycle parts sales enterprises in China is still very low, but with the increasing popularity of computer application and the intensification of market competition, it has become an inevitable trend for bicycle parts enterprises to adopt computer management in business, finance, production process and many other aspects. There is still a long way to go in computer management of bicycle accessories. However, traditional enterprises must conform to the choices made in the information age, and information management and operation is the only way and reform road for bicycle parts enterprises.
system analysis
This system consists of 14 parts, namely, outbound registration design, inbound registration design, outbound return design, inbound return design, inventory query design, outbound query design, inbound return query design, commodity information design, customer information design, supplier information design and system management design. 1. The outbound registration design is mainly used for daily outbound invoicing and automatic amount calculation. Automatically generate a 6-digit outbound ticket number, and there are many settlement methods. 2. The warehousing registration design is used for daily warehousing invoicing and automatic amount calculation. Automatically generate a 6-digit warehousing ticket number, and there are many settlement methods. 3. The outbound return design realizes the outbound return function, automatically calculates the amount, and automatically generates a 6-digit outbound return ticket number. There are many settlement methods. 4. The warehousing return design realizes the warehousing return function, automatically calculates the amount and automatically generates a 6-digit warehousing return ticket number. There are various settlement methods. 5. Inventory query design can query inventory information according to different fields and different conditions, and supports quick browsing of inventory information. 6. Inventory design is mainly to display the information of all goods with inventory quantity greater than 0 in the form of table appreciation. 7. Different fields and different conditions can be selected to query the corresponding information in the design of outbound query, inbound query, outbound return query and inbound return query. At the same time, it supports date query, browsing the corresponding commodity information in various ways, and browsing the corresponding information quickly. 8. Commodity information design, customer information design and supplier information design can add, modify and delete corresponding information, browse corresponding information in various ways, query corresponding information according to different fields and conditions, and support quick browsing of corresponding information. 9. The system management design calls the "Add User" and "Modify Password" windows to complete the corresponding operations and confirm the identity of the administrator.
Expected goal: computer management informationization. The operation is simple and easy, and the query is convenient and flexible. The system integrates procurement, sales and warehousing. The system has strict internal control and strong reliability. Detailed filing and review, the security and confidentiality of the application system is more perfect. The system has clear structure, beautiful and friendly interface, comprehensive functions and perfect data storage security. Integrate its management mode, management ideas and methods into the ideas and methods of modern management enterprises. Promote to a new management level. Improve the quality of employees.
System specific design
4. 1. 1 The concepts and methods of software engineering run through every step of this graduation design process.
4. 1.2 Use the life cycle method and prototype method to develop this system.
The so-called life cycle method means that system development completely follows six stages: system planning, system analysis, system design, system implementation and system operation and maintenance. Prototype method is to do some investigation and research on relevant parties according to users' requirements, quickly develop a management system, give it to users for use, put forward new requirements according to the problems found by users in the process of use, and constantly modify it until users are satisfied.
4. 1.3 Pay attention to the portability and maintainability of the system.
4. 1.4 Pay attention to the availability of the system.
4.2 Database system and system front-end development tools
4.2. 1 The database is sql server.
PowerBuilder9.0
A.PowerBuilder 9.0 has good expansibility, strong portability and stable performance.
B it provides numerous descriptors for creating and managing different objects, thus greatly reducing the development difficulty of object-oriented application systems and improving the development quality and speed.
C. It has powerful database operation function.
Demand analysis
1 Requirements Description and Analysis
It is the first and most basic to design a database system with good performance and make clear the requirements of application environment for the system. Especially, the application of data is very extensive and complex. If the information is not fully and carefully analyzed in advance, the design will be difficult to succeed.
Through the demand analysis stage, the overall application of the book management system is investigated in detail, the objectives of book management are determined, the basic data supporting the overall design objectives of the system and the demand for these data are collected, the needs of users are determined, and they are written into documents acceptable to users and database designers.
In fact, requirement analysis is one of the most difficult tasks in database development. Because, first, the system itself is variable, and the needs of users must be constantly adjusted to adapt to this change. Second, it is difficult for users to understand the functional processing of a certain part of the work. Therefore, designers must realize the importance of users' participation in the whole process of requirements analysis and system design, and conduct investigation and analysis through various methods.
Two steps of requirement analysis
Demand analysis can be roughly divided into three steps, namely, demand information collection, analysis and audit.
1. Collection of demand information
The collection of demand information is also called systematic investigation. In order to fully understand the possible needs of users, we should make full preparations before the investigation and study, and understand the purpose, content and method of the investigation.
2. The purpose of the investigation
First of all, we should understand the organization's institutional setup, main management activities and functions. Secondly, it is necessary to determine the objectives of the organization and roughly divide the management process and task scope.
