guarantee availability, allowing users uninterrupted access to the services provided by the software? How to collect the data generated by the software to provide a basis for the next phase of work? When we fully understand these two problems, we can design the corresponding architecture.The use of software
"Opening restaurants and making software"--a debate on architectureChandler:In fact, the software architecture is not the so-called right and wrong points, only is not suitable for the points, in fact, the essence of architecture is layering, but there are costs, layering must have the cost of communication (of course,
Design:
First, object-oriented language is a better structured language. Compared with non-object-oriented languages, it can better implement encapsulation, reduce coupling, and allow designers to think at an abstract level. These factors provide conditions for excellent architecture design.
Second, the object-oriented language allows designers to focus only on
stuff. This is also true for the software architecture. After online queries and books help, I figured out a rough outline.
The software industry is an industry that is keen on making 'terminologies. If it is returned for 15 years, it is estimated that few people will know what 'Software framework' is. In the 1980s s,

* Industry applications with this architecture may have more cabinets, which can affect the selection and conversion of performance metrics;
* Each link is basically the exchange of data messages in the manner of communication, the format is often more complex.
So the system is a test for the depth and breadth of the knowledge of the test engineer. For such a system, how to use the test strategy, how to analyze test requirements,
The multi-view method is not only the architecture archiving technology, but also the method of thinking that guides us in architecture design.
The more complex the system, the more you need to design the architecture from multiple aspects, in order to study and express the

The basic service is data scrvice. games or virtual worlds use it to store, read, and operate all persistent data.
The second stack-level service is 'Task service', which is used to schedule or execute tasks.
of division.
On the one hand, for communication consideration, if the architect does not adopt the view mode, it will be difficult to communicate with different personnel.
On the other hand, software architecture is a very complex thing. In architecture, many concepts and technologies are involved, and methods that are conducive to the

Recently, I have been paying attention to zhang3's research on new programming languages in Douban [1] and some related discussions. Here is a place that fits with my key domain model and modeling and architecture, that is, the

For example, in contract management, list, delete, need to distinguish whether the contract instance is created by the current user.5. Principles:The right logic fits the business logic. That is, the priv
important to use design models to connect the gaps between requirements and code. design models can capture errors and problematic assumptions long before development and testing.
