stock management database design

, the sales director only defines the function permission, but does not define the data permission, so the sales director can view all the sales orders; the other sales managers define the data permissions for this function, so they can only view the sales orders of the specified department. In practice, a department group is often used. The team lead can view the sales orders processed by all the personnel in the group, and in some cases, some people can only view their own sales orders, these

data from the streamline database in the last few days to the memory. 3) interface query service call gemfire client API query entry flow. 4) The transaction streamline splitting service reads data from the Message Server for processing and writes the splitting results to the Business Database. 5) Each web sub-business system must rely on the CAS service for single-point logon. 6) The unified user

attributes. Example 1: A simple management system for a mechanical manufacturing plant. First, design two partial E-R diagrams Based on the factory technical department and the factory supply department. The factory technical department is concerned with the product performance parameters, components, parts, materials, and consumption. The factory supply department is concerned with the product pr

, Therefore, only after the outline design is completed can the detailed design or the coding phase of the two WBS be accurately obtained, and the overall project scale is estimated to be more accurate. ）Logical AND physical location: which layer each object logically falls into, which module, which class, the physical each module, each object, each class on which application server or client, which directo

biggest feature is ease of operation, reasonable interface design, functions are the most practical, especially for DBAs, it emphasizes the MySQL runtime parameters and performance monitoring. 9.SQLite Manager SQLite Manager is an open source SQLite management tool that manages the SQLite database on your local computer, runs independently (in XULRunner mode),

If these two conditions are met, it can be explained that the standard of the database is still relatively high. Of course, this is a two-generalities indicator. In order to meet the requirements of database design normalization, the following five requirements are generally required. Request One: Nullable columns should be avoided in the table. Although emp

, 10 million), the complex calculation should first be outside the database, in a file system with the C + + language calculation processing completed, the last to add to the table. This is the experience of telecom billing system design.(3) If you find that there are too many records for a table, such as more than 10 million, you want to split the table horizontally. Horizontal segmentation is done by divi

the database, and the storage management of important information, through the main interface to the background data management, such as: Information entry, modification, deletion and other operations. the system has the following functional modules: Student Information Management module, Student information query mod

like this. When the program function is limited and the data volume is small, it is no problem to run the program. However, if it is used to manage important data, high risk. 2 The system has learned the data structure, but has not developed any management software programmers who require high program efficiency. Most of these students have just graduated from school. When designing the database table stru

"Experimental Purpose": understand the use of SQL language, further understanding of relational operations, consolidate the basic knowledge of the

I. Introduction ASP. NETIt provides powerful design functions for the network system design, which is easy to use and easy to use. It is a good choice for developing network systems. In network system design, user permission management is an indispensable part. The design
