mdm database architecture and design

Android app architecture design 01, androidapp1: This article has been excerpted, 12345 -Consistency of requirements, designs, and codes during development-the entire program has a uniform style, such as a dialog box style, button style, tone, and other UI elements-the specific and unified structure of the entire program, for example, when different modules access the network, their calling met

-tier architecture and MVC relationships:They're two unrelated things, classic three-layer architecture is a layered thinking, the development model is divided into these three layers , each person according to their own expertise, the development of different modules, such as front-end engineers, then the special research presentation layer can, how to make the page more beautiful,How to attract others, an

good development? The active record pattern is the closest mode to DDD, which takes a row from a table in the database as its own object field, and then wraps the data fields and business logic in an instance object around the business logic that expands on those fields. The active record mode differs from the table module pattern in that the table module pattern is an object that corresponds to a table in a

specific circumstances of the problem. These three examples are typical. In the second example, you may need to strictly divide it into three layers and add another mediating layer. Example 3 is not required. If you only want to view data, you only need several server pages to place all the logic. I usually separate the presentation layer from the domain layer/infrastructure layer. Unless the Domain Layer/infrastructure layer is very simple, and I can use tools to easily bind these layers. T

Some time ago after reading the "Internet Age of Software Revolution: SaaS Architecture Design," The book, feeling quite deep. Although many enterprises in 2000 to engage in ASP (Application service Provider, application services provider), but rarely see someone can write a book to share some of the knowledge, this book although write later, but also in the software industry has done a meaningful thing. In

assembles the parameters to be provided by the list. Necessary features What kind of data does list need to manipulate? How does list hold data? It is held by reference or by means of deep copy. Do we use polymorphism for data operations? Optional features Do you need a variable record length?-> If the data type to be long is int short or long Do you need tracing? Does it mean that we want to track the process and print the process information? To

Design of large-scale high-performance ASP. NET System Architecture The large-scale dynamic application system platform is mainly designed for the underlying system architecture built for high-traffic and high-concurrency websites. The operation of large Websites requires a reliable, secure, scalable, and easy-to-maintain application system platform to ensure

ProgramIs the overall organizational structure clear? Does it contain a good architectural perspective? Are major constructor blocks clearly defined (including the responsibility scope of each constructor block and interfaces of other constructor blocks )? Is it clear that all the functions listed in "requirements" are included (there are not too many construction blocks for each function )? Have you described and demonstrated the key classes? Have you described and demonstrated the data

model? Now let's look at LMAX as an actual example of my thoughts. In this design, theoretically, you do not need to require a single thread to access the model, because the domain model does not depend on any external state, it only depends on the memory space in which it is located. a major benefit of a single thread is that it can prevent concurrent conflicts. In fact, we fully support multithreading or cluster methods, but the status of objects i

I need, or refer to the design ideas, rather than the entire framework. Most of the frameworks I see are not focused on creating efficient extensibility and modularity. Q: Don't developers need frameworks or architectures? A: The site does need to have architecture, everyone needs a framework, the framework is a way to solve the problem. But you don't need a generic framework, with a front-end controller

problems that need to be further improved. In subsequent articles, we will discuss the following issues in the MySQL cluster in turn : Problems facing the top-level system: in MySQL a master multiple from the cluster, there is a service node. So when the upper business system is doing database operations (whether it is a write operation or a read operation), do you need to know these specific service nodes explicitly and connect them? It is

specifically introduced zookeeper, this topic does not explain the basic operation of zookeeper), if you have other functions in the actual work/ Technical requirements, you can also design the "Service State coordination module". In the process of business system integration, the role of ESB middleware is to make atomic service calls, transform data, invoke principle service calls, and re-convert between various business systems. Finally, the resu

a complete e-commerce system, divided into front-end trading system and background operating system, front and back of the common library is a traditional enterprise in the design of e-commerce projects a common practice. But this has caused a lot of trouble on the line. At the peak of the foreground trading system, the database itself is already under a lot of pressure, if the background job system produce

it is called through an interface, it can be configured to specify an implementation that points to WCF, so it also encompasses all the features of the WCF framework. After completing the development of the Web API layer, the integration based on the Web API layer is my next stage of work.We further analyze the implementation details of the hybrid framework, the traditional WinForm Access database and the way WCF services are accessed through a confi

The system architecture design of SAP is undoubtedly worth learning. The following are some information I collected from the network and can also be used as a reference for architecture design. 1. Implementation, development and maintenance process management are meticulous, with clear roles. Even in the project devel
