The functional requirements of the system refer to the specific business requirements of the system, that is, it is separated from the technology, but only the set of functional requirements of the system business. The purpose of our design of the project information management system of real estate enterprises is to use computer technology to optimize existing business processes, so as to achieve the purpose of improving work efficiency. We use computer information tools to participate in information management. The new management concept is to solve the problems of information redundancy, errors, and poor information circulation in the old model!

The functions of this system are mainly divided into: information management of real estate construction, information management of houses for sale, information management of houses for sale, and information management system of real estate enterprises.

The following will briefly describe the four sub-information management systems mentioned above.

1. Information management of real estate construction: including functions, plan inquiries, and specific building number inquiries. The plan query includes information budget statistics, expected completion time and customer opinions, and the specific building number query includes application materials, progress statistics, and employee information.

2. Information management of real estate for sale: mainly for inquiries about remaining real estate and policy inquiries.

3. Information management of sold properties: inquiries about sold properties, customer feedback.

4. The internal information management system of a real estate enterprise mainly includes information notification functions, knowledge sharing platforms, mobile terminal reminders, daily work arrangement functions, business process management, document recording functions, and communication record maintenance functions.

The specific explanation of each sub-function will be described in detail in the system function requirements below.

Based on the object-oriented idea of java development, the drawing tool is displayed in UML using the functional requirements of the system. Through the display of drawings, the functional requirements of the system can be displayed more vividly, which is more intuitive, easy to understand, and easy for readers to understand. A use case is that the specified actuator can see the interaction between the user and the computer in order to achieve a certain purpose, that is, a series of tasks performed by the system. This use case describes some visible needs put forward by the user and achieves specific user goals. We respectively show the use case diagrams of the four subsystems involved in the functional structure diagram of the project management information system of the above-mentioned real estate enterprise.

 one. Demand analysis of Real Estate information management system 

1. Plan query: Mainly query the budget statistics and corresponding expected completion time in the process of real estate construction. From the perspective of project management, the purpose of this program query is to monitor the progress and cost management in the project implementation process. Customer opinions can be regarded as system quality. The purpose of querying customer opinions is to monitor the quality of the project.

By querying the budget of the plan, the expected completion time and the customer's opinions on the real estate plan, the real estate construction management personnel can analyze the overall construction situation of the real estate, evaluate whether the budget for the next step will increase or decrease, determine whether the project progress is smooth, and improve the real estate construction process based on the customer's improvement opinions. The plan query function provided by the system first selects the plan that needs to be maintained by the sales staff, and then enters the plan budget, expected completion time and customer opinions on the real estate. The system saves the real estate-related data entered by the sales staff. After that, the manager uses the plan query function, enters the query conditions, real estate number or real estate name, and queries the real estate budget, expected completion time, and customer opinions on the real estate.

2. Query for specific building numbers: the query includes application materials, progress statistics, and employee information. It is mainly used to monitor each real estate in the implementation process of specific real estate projects. Monitor the overall construction of the real estate according to the building number.

The goal of the specific building number query is the specific goal of each building. During the construction process, there will be many buildings. In order to monitor each building well, we will number the buildings. Sales staff should enter the application materials, progress and employee information for each building. With the construction of the building, the relevant information of the building needs to be maintained simultaneously. Administrators or leaders can check the detailed information of each building, including application materials, progress, and employee information, by entering the building number. The system provides maintenance functions and query functions for each building.

two. Demand analysis of the Information management System of Real Estate for sale

Examples of real estate information management systems for sale The use case description of the real estate information management system for sale is shown in Table 2-2.：

1. Information management of real estate for sale: it is mainly used for inquiries about remaining real estate and policy inquiries. Its function is to assist in real estate sales and is an effective tool for the sales department to sell real estate. In the implementation process of specific real estate projects, each real estate. Monitor the overall construction of real estate according to the building number.

Once the real estate has obtained the pre-sale certificate, it can enter the sales stage. As the number of real estate increases, in order to better manage it, it is necessary to distinguish between sold real estate and for sale real estate. Once the real estate is sold, it will enter the sold real estate information management system for management and maintenance. This system, with the query function of real estate information for sale, provides inquiries about remaining real estate and policy inquiries.

The requirement of the inquiry function of real estate for sale is that after buyers and customers come to the sales office to understand the real estate, they will propose to the real estate consultant which families can buy it after communication. Real estate consultants can provide customers with information by using the remaining real estate query function to obtain real estate information for sale faster and more accurately. The main demand lies in the need to provide query functions based on various query conditions such as unit price, total price, apartment type, area, direction, etc., whether it is transparent or not. The more query conditions you choose, the more accurate the query results, which can reduce the time to select rooms for customers and provide customer service satisfaction.

Querying the information of sold real estate is mainly aimed at the return visit service of old customers to improve the overall satisfaction of customers. Generally speaking, developers have some customer activities every week. In order to facilitate the notification of every old customer, ordinary customers have a real estate consultant when buying a house. In order to facilitate the management of real estate consultants to contact the owners, real estate consultants can quickly query the owners of sold real estate through the information of sold real estate, and then quickly contact the owners. In addition, through the data analysis of sold real estate information, developers can obtain basic data on best-selling real estate such as floors and apartment types, so that real estate consultants can recommend houses to different future customers.
