Introduction
Generally speaking, management is through planning, organization, guidance and leadership, control and other means. Set goals for the organization to achieve value. With the development of society and the change of people's demands, people pay more and more attention to the role of information in production and management and enterprise management, and regard it as a very important resource, which is the " information resource" in today's big data era, and the processing of data ( information ) has become a key social activity in today's world. The foundation of the birth and development of information management system is hardware and software - that is, computer and other electronic devices. The computing speed of these devices is far higher than that of human brain, so it will be much more efficient to replace human operation in some aspects. The house intermediary management system is similar to the information management system, but it only embodies the information of each management. And the housing intermediary management system can more effectively and conveniently handle the operation of renting and asking for rent between houses. This system uses JSP to develop front-end and SQL to solve back-end problems. In this system, the information of people ( renters and sellers ) and houses is particularly important. Therefore, when building tables in the database, we should attach great importance to the establishment of information about tenants and sellers, as well as the establishment of basic information and expanding information about houses.
REQUIREMENTS ANALYSIS
The requirement analysis of housing intermediary enterprises system mainly carries on the work from the two aspects of functional requirements and non-functional requirements. Functional requirements include the actual investigation of the enterprise, and combine with the actual business customer needs to design corresponding functional modules. Housing intermediary management system described in this paper mainly includes five function modules, which are user basic information management, inquiry management, employee information management, rental management and system management. Housing intermediary enterprises system non-functional requirements must reach the scalability requirements, ensure data security and stability, flexible process daily tasks and problems, and be able to provide reliable data information storage services.
SYSTEM ANALYSIS AND KEY TECHNOLOGIES
SQL Server database profile SQL Server is a relational network database management system of Microsoft Corp., which supports XML and Internet standards, and has Web based analyzing ability. Because of its powerful function and easy operation, it has been increasingly favored by database users. Microsoft SQL Server 2000 is one of the most widely used database systems, and it is the most widely used server in small and medium enterprises. SQL Server has the functions of distributed database and data warehouse management, supports the C/S architecture, and has the ability of distributed transaction processing and online analytical processing. In addition, SQL Server has a powerful data management capabilities, it provides a wealth management tools to support data security management, integrity management and job management. (2) C# language development program introduction C# is an object-oriented programming language developed by Microsoft Corp., which runs on.NET Framework. C# advanced programming language design and development inherited the advantages of C language and C++ language. It improves the code development efficiency and compilation efficiency, provides more interfaces and services, and has become the most popular software development in the field of high-level programming and development language. (3) Framework.NET brief introduction .NET Framework is a software development platform launched by Microsoft Corp.. It supports the object-oriented technology, provides the public class and the basic class which can be called, provides the corresponding interface and service, advances the code reuse rate and development efficiency, reduces development time, and enhances work efficiency. .NET Framework can provide a safe and stable software developing systems, unsafe code to debug and compile in the sandbox, it will not have any impact on stable code, to ensure the code safety and stability
DATABASE ANALYSIS AND DESIGN
According to the system analysis and function design of housing intermediary management system, it mainly includes employee information entity, customer information entity, housing entity, inquiry intention entity, expense information entity. Housing information entities expressed specific information of renting housing, such as housing number, property name, decoration information, architecture, story, building age and so on. The software system database design needs analysis and reference software system results, feasibility analysis, to ensure data unity and security information. Design structure in database, a variety of data tables in the database system design as needed. A brief primary coverage analysis of entity relationship model。
For rental demand customers with rental demand information entity express their intent information of rental sources, including intention number, customer ID, house type, decoration information, story, direction, housing application, etc.. The E-R diagram of the entity。According to the entity E-R diagram, main database table structure design: (1) Customer information table (TB - user): including customer ID, name, gender, date of birth, home phone number, mobile phone number, email, ID number, customer type, house number, recording date. (2) Housing information table (tb_house): including the house number, name, room number, house property, decoration information, rental price, story number, construction area, customer ID. (3) Housing rental demand table（tbjntent): including intention number, customer ID, room number, house block, decoration information, story number, number, rental price, house application number, etc..
Collect fees information table (tb_moneyAndInfo): Including cost number, fee amount、eanalysis, to ensure data unity and security information.mployee number, employee name, house number, date of payment, remarks, housing rental person ID, housing rental person name, phone number, housing rental demand person ID, etc..
SYSTEM DESIGN
In the software engineering development process, during software system design phase, according to important steps of software system and the main content of system software design, to provide the required result analysis and feasibility analysis, and combined with practical use of environmental design of customer software system, basic functional structure of software system are designed and identified main business processes of major software systems. Software system design can ensure software system development process to avoid some unclear problems, so that it can determine high quality software system through defining functional blocks and development plans in each phase. According to system module analysis and design of housing intermediary management system, the specific function structure diagram。
SUMMARY AND OUTLOOK
The housing intermediary enterprises system can meet the functional needs of users and be processed steadily through the system analysis, system design and system development stage. Through understanding of housing intermediary enterprises related business operation flow, we put forward some ideas and prospects for future development and software system upgrading: 1. In the future, housing intermediary enterprises development is faster and faster, with business volume increasing, data storage and data processing speed of software system becomes higher, it is necessary to provide large storing of software system and optimized processing speed. We can adopt distributed processing and big data processing technology to ensure software system data processing speed and accuracy rate. 2. In housing intermediary management system, there are some deficiencies in human-computer interaction and system interface design, and operation interface is monotonous simple. 3. After the software system is delivered to customers, it is also necessary to investigate operation of software system on a regular basis, and visit customer experience software system to analyze running state, maintain and upgrade software system according to user's requirement.
