framework. (From Lin xing)Here is a small example of system performance and reliability problems caused by architecture design problems caused by incorrect customer requirements in the past few years: the requirements of this system are relatively simple, scan and store all history file cards of a business in a city so that you can search by name. In the demand phase, the customer said there were about 0.2

purpose of the flow queue data is to determine the data in the table where the data will be keptis insert,update and delete, and each operation generates the corresponding log information. In MySQL, if theThe storage engine that holds the transaction, the amount of this log generation is doubled. And if we go through some mature third-party queue software toThe performance of this queue data processing function will be multiplied.3. Super-Large text dataFor MySQL versions prior to 5.0.3, the VA

Implementation Details of software modules to reduce the impact of future changes. In fact, the first supported programming concept for separation of focus is procedural programming. In procedural programming, separation of focus depends on functions and processes. However, the concept of separation of focus is not limited to programming languages. It goes beyond the pure programming field and applies to many aspects of software architecture. In Serv

, components in a software system are logical components first. How these logical components are put on the hardware, and how they contribute to the scalability, reliability, robustness, flexibility, and performance of the entire system are very important information. Second, the decisions that need to be made for software design will inevitably include the logical structure, physical structure, and how they affect all the non-functional features of t

multiple structures. Common Software structures include: module structure, logic or concept structure, process or coordination structure, physical structure, usage structure, call structure, data flow, control flow, and class structure.Ii. factors to be considered in Architecture Design:The module architecture design can be considered in terms of the program run

low-cost, scalable solutions to database-side applications with large read-stress ratios. Because as long as the pressure of master and Slave is not too great (especially the Slave pressure), the delay of asynchronous replication is generally very small. Especially since the Slave end of the replication mode changed to two thread processing, but also reduced the Slave end of the delay problem. The benefit is that the real-time requirements of the dat

be updated independently Updating a service does not require changing other services If you have a bunch of small services that you can't update independently, that's not a micro-service, because these services are not loosely coupled. One reason is that some companies will split the application, but not split the database, all applications still access the same database, you need to split the

The original idea is to teach you how to use AgileEAS step by step. NET base library for application development-articles related to the series of directories to gradually explain Based on AgileEAS. NET platform for application development, but in the case of the process, we have to talk about AgileEAS. in terms of Architecture Design for application development on the NET platform, I will separate some art

Design of computer CPU architecture RISC eventually defeated Cisc, creating the mainstream of today's PC. Software architecture design is the same, in the case of accomplishing the same thing, strive for simplicity. This evening I had a long talk with the chief scientist and the boss of the former company until 2

the dedicated employeelogic directory. There are many advantages, and the most relevant thing is the project task allocation, after the design is complete, some logic can be abstracted out and the interface can be allocated to someone for implementation; This section mainly introduces the background. Next we will perform a high degree of analysis, design, and configuration on the business logic of [employe
