Always feel that the model layer is only used to manipulate data, a lot of business processing in the controller, there is a claim that business logic is more suitable for the model layer, do not know which processing better! Look at the tp5.0, as if the business logic in the model, and then read some stickers, many say business logic in the model better. Links:

Logic (rationale), derived from classical Greek λόγος (logos), originally meant "words" or "words", but also extended meaning "thinking" or "reasoning". Logic is often considered to be a study of the evaluation criteria of argumentation, although the precise definition of logic is controversial among philosophers. The subject is also based, and the task of the

sqlexception thrown by test, the catch is used here, and for appexception, it is added to the throws statement of its own method, which means that the current method is not processed, or it is handled by the upper layer.Checked contrast unchecked ExceptionAbove, you can see the difference between runtimeexception (unchecked exception) and checked exception, checked exception must appear in the throws statement, the caller must handle, The Java compiler enforces this, and runtimeexception does n

C # Developing the game object's behavior logic method of Unity game tutorial The behavior logic of game object--methodmethod, the reader in the 1th chapter of the new script has been seen, and in the 2nd chapter on the overall introduction of the script is also introduced, then the last chapter, although the main content is variable, but at the end of the chapter in order to show the game effect, also used

Summary of. NET logic layered architecture I will analyze the real mysteries of the. NET layered architecture from another perspective. Layering: Some programmers with weak technical skills will think of a layer-3 architecture (BLL, DAL, and so on) when they hear it. Actually, layering is a big technical framework, the three-tier architecture only breaks down information flow through three layers for common information systems, 　I. Basic Knowledge pre

The difference between the line network and the variable Reg may be the most difficult for beginners of Tilde. Sometimes you have to use Reg, but sometimes you have to use wire. In systemopengl, we will see that you can replace reg or wire type with logic type in the past. In fact, logic improves the reg data type so that it can be driven by continuous assignments, gate units, and modules in addition to

I. Basic KNOWLEDGE Preparation: 　　1. The principle of the layer: (1) Each layer is provided with an interface for Upper call.(2) The upper layer can only call the lower level.(3) Dependence is divided into two kinds: loose interaction and strict interaction. 　　2. Classification of Business logic: (1) Application logic.(2) Domain logic. 　　3. The layer used:

Logic tag Library This tag library can be divided into three types: condition, loop, and forwarding/redirection. I.) Condition Type Logic: Empty and logic: notemptyLogic: the empty label determines whether the script variable is null, whether it is an empty string (the length is 0), whether it is an empty collection or map (call the isempty () method to determi

. NET Framework 4 When working with data in ASP, you can benefit from using the generic software model. One of these patterns is to separate the data access code from the business logic code that controls data access or provides other business rules. In this mode, these two layers are separated from the presentation layer. The presentation layer consists of pages where the site user has permission to view or change data.ASP. NET provides a v

In many new enterprise system designs implemented using SQLServer, system designers need to make key decisions on the positioning of data structures and management application logic. SQLServer has its own programming language (Transact-SQL, TSQL). developers can use it to manage data access, code transaction logic, and transaction control. Use TSQL, In many new enterprise system designs implemented using SQ

From the perspective of gctexamination, the logic knowledge and Examination Form are limited and focused. Even though there are more than a dozen courses in the software designer examination, as long as you know how to strengthen understanding and use of important knowledge points and examination forms, the examination is easier to find a pass. However, whether it is a software designer or gcttest, if it is purely for the test, it will lose the meanin

The Business Logic layer (Business Logic Layer) is undoubtedly the part of the system architecture that embodies the core value. Its focus is mainly on the development of business rules, the implementation of business processes and other business requirements related to the system design, that is, it is related to the domain of the system to deal with the logic,

Introduction: Using the Rules engine can reduce the maintenance and scalability costs of applications by reducing the complexity of components that implement complex business logic. This updated article shows how to use the open source Drools rule engine to make Java™ applications more adaptable to change. The Drools project introduces a new local rule expression language and an Eclipse plug-in that makes Drools easier to use than ever before. Most o

ORACLE application optimization: Please avoid SQL processing in a large number of cyclic logic, oracle Optimization I encountered a case a while ago: a colleague said that a previously running package was suddenly much slower than before and the execution time was very long, in the evening, the job calls this package and does not run data for several hours. So I located an SQL statement in a stored procedure in the package during the tracking and opti

SQL execution time within the cursor takes 2 seconds, previously only 30 cycles, then the SQL needs to be 2*30=60 seconds, if the number of cycles suddenly increases to 8,000 times, 2*8000=16000 seconds, this is a few hours of time. As you can imagine, this performance suddenly drops to an intolerable level! So how to optimize it? Reduce the number of cycles, of course. After a careful look at this SQL, figuring out the business logic of the man who

This article mainly introduces how to use the business logic of CodeIgniter controller, and analyzes the related concepts and specific usage of the business logic in the form of instances, for more information about the business logic of CodeIgniter controller, see the following example. We will share this with you for your reference. The details are as follows:
