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

There is a trading business with multiple business logic, to give a simple example of a payment transaction that may have cash, shopping coupons, discount cards and the like to pay at the same time. The normal logic is that each payment type is a transaction, which requires multiple transactions to be opened at the same time, and if there are other combinations later, the transaction will be more. In thi

Will the logic be written to the model using the php framework? Or is the model only used to add, delete, and modify data? Where do you write the logic in a simple mvc framework? Controller? Or do you have a logic layer? Will the logic be written to the model using the php framework? Or is the model only used to add,

Introduction The data access layer, described in the first section of this tutorial, is a clear distinction between presentation logic and data access logic, as in the case of Layer, the following referred to as DAL. However, even if the DAL separates the details of data access from the presentation layer, it cannot handle any business rules. For example, we may not want the "category number" or "vendor nu

In the snapping scene, make sure two points:1. Inventory will not be reduced/less sold2. Speed of execution on 1 basisI tested two scenarios,Programme I. MySQL Open transactionI simply designed the inventory table as followsCREATE TABLE ' La_store ' ( int(notNULL ,int( 255notNULL, PRIMARYKEY (' id ')) ENGINE =DEFAULT CHARSET=utf8mb4;Assuming 100,000 items in stock (val=100000)PHP Logic CodePHP$stime=Microtime(true);$count=100000;//Number of test

two recommendations:-When using constants, it is best to use constants of the corresponding type. For example, if Table.col is a varchar type, then a query of where Table.col = 10 will not be able to use the index, and an error will occur when it encounters a value in Col that cannot be converted to a number.-unless the implicit conversion of the corresponding value is very intuitive, it is preferred to specify explicit explicit conversions with cast ()/convert ().In the above content, the unde

Stored Procedures | Encapsulation SQL Server 2005 can write stored procedures in. NET languages, so in small and medium applications, it becomes a good choice to use the stored procedure encapsulation application logic. The advantages of using stored procedures to encapsulate application logic are as follows: 1, Dba+developer Division of labor Clear. Code modularity between. Reduce database operator and
