Summary of RFID conference sign-in system (xiii)-module Overview (II)

 

The previous sections describe the modules of the check-in terminal.ProgramIt is much easier to do, but the actual implementation still requires a lot of energyUIIt is always laborious to do something. However, the technical level is relatively low, not to mention that it was not very well thought out at the time (even ifUISo there is nothing to talk about here. For further refinement, we will start with this article and focus on the control end.

 

The module division of the check-in terminal focuses on the technical architecture, and the module division of the Management Terminal focuses on the business functions.

the control end is a relatively familiar program with various forms, including menus, toolbar, and status bar. Because of the Business complexity of this sign-in system and ERP , we directly integrate all forms and functions into a large set of programs, and add the aforementioned data access and communication components to form a control-End program. However, this approach seems to be unpursued and does not comply with the standards for excellence, so it is a great deal of effort. Of course, the premise is that the project does not have much time pressure.

The most important purpose of a management form is to manage data, while the management data is similar. Therefore, a basic class of a data management form is essential. At the same time, there are always many data display controls to manage data,IDEIn general, the built-in controls cannot fully meet people's requirements. It is also necessary to create some user controls. In this way, the basic layer of a form is independent.

Although there are not many business functions of the system that need to be checked for manuals and systematic training, there are still 20 or 30 items in total, and it seems a little huge to put them together, this is too difficult for future changes. More importantly, if you divide business functions, it is more flexible for commercial promotion. You can combine different functional modules according to different situations, although there is no need in this regard, it seems that there is no commercial plan in this regard. However, it is necessary to move forward in system design.

 

Data management is one of the most basic functions of the control end. It is possible to make it an independent one. However, considering this is the most basic function, no matter how the requirements change, data management is always necessary. In the end, this part is not a separate assembly, but directly written into the main program.

The management terminal is a required function of the Management Terminal. The "management" is previously implemented in the main program. Do you want to add "control" to the main program? In simple cases, there is only one check-in terminal. At this time, it is not necessary to manually enter the check-in terminal and the Management Terminal. You can simply use a single-host system. At this time, the so-called control end can be degraded into a pure data management program, so it is wise to turn the sign-in control in the control end into a separate one.

The printing function is also an important function of the system. However, although printing technology cannot be varied, it is not just a unique choice. It is not impossible to change Printing Technology for various reasons in the future, in addition, this function is pure, and it is easy to stand out independently. In addition, if some customers say they do not have to print paper results (although this is not possible at the moment), simply add a module.

Previously, the "function overview" mentioned that this system is a "one-stop-sale" design, which adds a data backup and recovery function, this kind of product based on special design is of course easier to come out independently.

 

in this way, in addition to the basic modules of data access and communication, the control end also separates three modules: sign-in control, printing, and data processing.
