An Information object should contain all the information of a record in a data table, and can also implement all relevant operations of this information, such as addition, deletion, modification, and search. The business operations in the middle tier are implemented using the Management class. The top level presentation layer is implemented using JSP. The JSP is only concerned with data representation. As for the transfer of data to the middle layer, Struts Action is used to implement the data, and the data is encapsulated into a Model object and transferred to the Management layer of the middle layer. Then the Model object is placed in the management layer of the middle layer. Reassemble the specific In-formation object to implement the underlying database operations.
The system is designed according to a three-tier structure. The data from the presentation layer to the business layer is encapsulated into the Model object in the Action, and the data from the business layer to the data layer is encapsulated into Information objects in the Management. In the following module design, the required methods and functional designs of the Informa-tion and Management classes are roughly given. No specific design is given for the Model class. The functions it should contain are only the encapsulation of the specific functional modules in the presentation layer. The data to the business layer should therefore contain a series of properties and their getter and setter methods.
Appointment Test Service System Appointment test service system includes three modules: user appointment management, test service management, and appointment service supervision. The user reservation management module includes three functions: reservation information, reply information, and test results, and is mainly for test users. After the user logs in, the system automatically judges whether it is authorized to enter the module according to the authority granted by the administrator. If this permission is available, the system first displays the basic information, reply status, and test status of the user's past appointments in reverse order of time. The module also supports double inquiry of reservation information within two conditions of "instrument unit", "instrument area", "instrument type" and "recovery status", and allows corresponding deletion and modification of the information displayed in the inquiry. And other operations. In addition, users can also add new booking information.
In order to facilitate user access control, the user management system simplifies setting of the user's authority through batch setting of roles. It is proposed to set the authority of the legal person management personnel through the system administrator, and the legal person management personnel shall set the authority of the subordinate unit laboratory or crew manager. Through the hierarchical management of authority, the responsibility of the system is displayed. Users are the direct operators of key business data. Therefore, it is necessary to conduct strict audits and management of users and their work situations to ensure the security and integrity of data. The main function of this module is to add new users, support modifying, deleting, querying and outputting its information, and can group and undo users and other operations.
System rights management design Enter each page to determine whether there is a user in the session. If not, add a Guest user in the session to ensure that the user always exists in the session. Perform permission matching before entering the operation module, eg. In addition, when the user clicks on a menu and expands a lower menu, the submenu should be loaded according to the user's role authority. One menu corresponds to one module. If it is not a menu directly corresponding to the module, it can be directly loaded.
Each operation data unit class (Information) should implement the method mathSubject, the incoming parameter is the user ID, the function is to obtain the user level and level unit ID from the registered user information table through the user ID, and then through a certain operation (each data The unit's methods are all the same.) Obtain the unit ID of the operation data unit corresponding to the user level, and then match whether it is the same as the level unit ID in the registered user information table, and return.
The database environment of the system indicates that the large scientific equipment and equipment sharing platform of Fujian Province is compatible with the “National Information Sharing Management System for Large Scientific Instrumentsâ€, as well as the interconnection and data exchange with the national and regional networks, and has chosen internationally in database management software. The first grid database Oracle10g.
