Part 3: Design Logic Layer: core developmentAs mentioned earlier, our solution is as follows:Below we discuss the structure of the entire application, separated into different layers according to the logical dependencies of the different components in the application, and the communication between the layers and the layers passes or does not pass the restriction. Hierarchies are architectural styles that address maintenance and scaling issues during t
This article continues with an example to gain an in-depth understanding of the implementation of bytecode for dynamic change methods of method components. By the previous article, you know that Classvisitor's Visitmethod () method can return an instance of Methodvisitor. Then we can also basically know that with classvisitor change class members, methodvisistor if need to change method members, inject logic, can also inherit Methodvisitor, To write a

The embedded logic analyzer sigbaltap II is an embedded logic analyzer that comes with Altera Quartus II. It differs from the Modelsim software simulation. It is an on-line simulation that allows you to more accurately observe data changes and facilitate debugging.
Many children who have learned single-chip microcomputer think that single-chip microcomputer can be debugged in one step
Design a flexible and stable multi-layer architectureProgramIt is not easy. With mature models and applications, you also need to experience various applications and requirements. To put it bluntly, you must be able to withstand the difficulties. Recently, when restructuring your EPN framework, I have some new experiences and practices to share with you.
The first is the database design. A framework database drives multiple business logic databases,
results must be the same or opposite. If it is the opposite, it is equivalent to a not ("not") gate electronic component. If it is the same, it will be interesting. Such a minefield will have the nature of circuit wires!Here, the minefield is regarded as a digital logic circuit. A circuit that performs logical operations such as "or", "and", and "Non" is called a logic gate. Any complex logical circuit can
There are many places where the business logic can be stored in a system. Some people choose to store it in the stored procedure, and some choose to store it in the business components. These methods can be used to determine the business logic. Since these methods can be used to determine the business logic, the rationality of their existence is proved. Just like
My service layer is the API interface provided to the Controller, is the business code written on the service layer or the Logic layer?
For example, a member needs to recharge a function:
A sequence of events is generated after the operation.
1 inside one of the update member gold operation, may have to update 3 sheets. Does this update member gold operation be encapsulated in Logic or Service?

What is WF series? [build a data logic layer based on WF and WCF]
What is WF? Many people who have some knowledge about NET technology can say something, but they cannot make it clear.
No matter what you think WF is, do not compare it with Jbpm, Shark, Biztalk, and SharePoint. These products share the same characteristics as products for enterprise business process applications, WF-oriented developers
WF is a process-oriented development platform tha

Logic Switches1) Bit in logic is also important, true or false can be expressed as 1 and 02) in Boolean algebra, operands are not numbers but classes, and a class is a group of Things (collections). In Boolean algebra, the calculation of a class is calculated using the intersection, the sum set,1 representing the complete, and 0 for the empty .3) Boolean algebra mapping to the representation in the cir

The use of the three-tier architecture, the need to study the BLL layer, that the business logic can be fully implemented in the controller, there is no need to do a separate project, another layer of many will affect performance. Later on, I made the business logic independent, for the following reasons:

Suppose I now have a table, where one column has a Time field, and I set it to expire in 2015-11-20.
I can write a logical judgment through the MySQL statement, when the server date equals the expiry time, delete the field, can I implement this function?
I now think of the use of MySQL dynamic execution process, but I think this logic for the MySQL server is not good, will produce performance problems, because the general

Hi everyone,
This is my first major asp.net project, and it's an Intranet application for a retail company. The basic architecture I am using has three namespaces:

1. The jmeter official website explains the logic controller as "logic controllers determine the order in which samplers are processed .". Logical controllers can control the execution sequence of samplers. It can be seen that the controller needs to be used together with the sampler, otherwise the controller has no meaning. All the samplervers placed under the controller are considered as a whole
