equivalent to overthrowing redo! If you do not overwrite the Redo, but modify the original code, the cost may be several or even dozens of times that of the original project. There are three major changes to a system: business, system architecture, and program implementation. 1. Business Layer: There are many solutions to changes in requirements at the

A: Overview of the Business Layer architecture modelIn a three-tier architecture, the business layer is responsible for all business-related work, including calculations based on input data or existing data, validation of data entered from the presentation layer, and determi

relationship with the operation object. In addition, the markold method of the base class is used to identify the object that has been processed and does not need to be processed. The subclass can override this method to provide its own implementation. Some other methods or attributes are required in a specific class. This is a good analysis. For example, for a client program, we only need to do this to complete data operations: Add article: 1 post

Document directory Service-oriented value (from the book of WCF programming) For the purpose of SOA, IBM says:The fundamental purpose of SOA is business agility. How to understand agility is understood from two aspects: first, it responds to this change in an appropriate period of time after the business changes are proposed; second, changes made by it can properly reflect

concentrated in a small memory as much as possible to avoid waiting events caused by cache fusion. For example, in the following example, this is an OLAP system with a RAC consisting of four instances (distributed on four servers). This database has two main functions, that is, data loading and data query. Since these two services are almost non-overlapping, we consider assigning them to different instance

implement the transaction script. If there are more and more associations between objects, your transaction scripts will become larger and larger, and there will be more and more duplicate code, and the project will be uncontrollable. For the domain model, its construction model is not static, and many of its variants are similar to activity records. The conventional approach is to map the domain model directly to the database, with no other layers in the middle. However, there is also a varian

Business Layer, you do not know the implementation details of the database This topic is also widely discussed on the Internet. Will your business layer contain your data layer-related architecture technologies? For example, your data layer persistence is implemented through EF, so should your

This is the eighth article in the agile development product management series. (Column directory) In product development, product performance problems are often encountered, which will greatly affect the product architecture. However, to solve these performance problems, do not think it is only a matter of technical personnel. The product manager and product director should also participate in the process, or even

Designing a business process platform based on WF-Architecture Recently, many of my friends asked me questions about designing business processes with WF. It seems that many of my friends have entered the WF development stage from their understanding of WF, so I have written a group of articles on business process pla

ChangePassword method in Adminbll, for example, invokes the Admindal GetByID and update two methods. In addition, although many methods call only one data access method, it can be seen from the naming to see the difference between the two. such as the Getbynameandpassword in Admindal, the name is clearly from the database point of view-refers to the specified name and password two fields of the value of the corresponding information, as the
