mdm database architecture and design

[Architecture design] 3-layer infrastructure three-layer architecture As long as you are a software practitioner, whether or not you are from a bachelor's degree, I believe there will be no stranger to the three-tier architecture. In a three-tier architecture, program code

Petshop is an example. Microsoft uses it to demonstrate. NET Enterprise system development capabilities. There are many. NET and J2EE competitions in the industry, and a lot of data comes from Microsoft's petshop and Sun's PetStore. Such a debate will inevitably have a strong commercial color. For our developers, there is no need to pay too much attention. However, with the continuous update of the petshop version, the entire design has gradually beco

structure, as shown in Figure three: Figure Three: Architecture of PetShop 2.0 We can see from the diagram that there is no obvious data access layer design. While this design improves the performance of data access, it also leads to confusion in the responsibilities of the business logic layer and data access. Once the requested

this article will help us understand the database architecture.1. Data splitting Solution When the database is large, read/write operations, especially write operations, are too frequent, and it is difficult for a server to support them, we need to consider splitting the database. The so-called

, isn't that right? Yes, but the sub-types under the product type are explicitly used in the definition of order, which means that there are two separate business scopes, and the normal understanding must be designed according to the table module pattern. Second: If it is designed according to the table module mode, because the naming of this object is obviously this pattern, but read the code to find the responsibility is still a little unclear, in the Order.addorder (OrderField OrderField) met

RESTful is the design idea used in both the front-end and back-end interfaces.The website is the software, we also often say webapp, this kind of Internet software uses "the client/server" mode, builds on the distributed system.Web site development, can also fully adopt the model of software development , but the traditional software and networks are different areas, because: software development is mainly for the single-machine environment, and the n

Whether It's physical or virtual, there ' s likely to be a story wall or Kanban board visualising the work yet to be started , in progress and done. Visualising your software development process is a fantastic it to introduce transparency because anybody can see, at a

"Schema Source Address"In the natural world, congenital defective organisms are always susceptible to bacterial virus intrusion, and robust mobs are more resistant to bacterial viruses, computer systems are the same, if there is a congenital architecture design security flaws, then in the face of cyber attacks, it is more likely to be invaded or destroyed, even because of the

OverviewThis translation was first published in a public number under Infoq: "Talk about architecture", thinking that I was nearly two years old in the garden, so I was resurrected. Hahaha, this is a translation of the architecture, will introduce a number of tools, as well as frameworks, to the architecture of interested students a knowledge expansion.In recent

The following are the main chapters of this article: 1. What is called "JavaScript large program"? 2. Look at the current program

Read the catalogue: 1. Background information 2. Simple Introduction table module mode, transaction script mode 3. Correct code for table module mode, transaction script mode 4. Summary 1. Background informationTo properly design the system architecture, you must be able to correctly understand the intent of each architectural pattern, not the beard and eyebrows cluth. Now there is

architecture needs to be upgraded and "evolved."Cloud Database Schema DirectionCloud database architecture is the key point of its ability to carry out the "cloud" of application architectures, and with the development of technology and business, the architecture of cloud

questions about the database, the Data Query layer is called. Presentation Layer: it is the UI part of the system and is responsible for user interaction with the entire system. In this layer, the ideal state should not include the business logic of the system. The logic code in the presentation layer is only related to the interface elements. In petshop, ASP. NET is used for design. Therefore, many Web co

, silently, constantly evolving the structure of the front and back. Leaving business to talk about architecture is purely bullying, and the development of each platform's backend architecture is a mirror of its business development. Are you hungry? Web site at the beginning of the time is probably just an idea: an industry model, the rapid production of it. "Fast" is the first place, and it doesn't take mu
