A few days ago, a few former colleagues came to my house to play, during which we discussed the current popular software architecture. Most of these colleagues now turn to software architect engineers and some want to grow into software architect engi
much easier to manage and maintain.5. LSP (Liskov Substitution Principle) Replacement principle
Subtypes must be able to replace their base types. If you inherit the parent class, but the subclass's method is completely different from the parent class, the subclass cannot replace the parent class, which violates the LSP principle
Personal SummaryA delegate is one of several alternatives to inheritance. A delegate or aggregation is a good way to fix a non-compliant LSP inheritance

unexpected situation, in order to better solve these conditions, we need certain norms and guidelines to work to assist, so the software architecture has its existence of necessity.What sort of software architecture does it have?Decision-making Composition FactionComposition Faction:The
performance is inversely proportional to the set of all waiting times for the entire system, any operation that increases the wait time faster than the load will become a problem. Despite all this, I would like to point out that if you find it difficult to meet performance and scalability goals, it's important to wonder if you've chosen the right architecture. Still, look at the big picture and make sure someone is taking the architect's responsibili

It is not easy to develop software that is satisfactory to users. Software architects must fully grasp the possible conflicts between various requirements and weigh requirements, different requirements are met in different categories. This article starts from understanding the complexity of the requirement types and demonstrates how to design the architecture
How to better software architecture design, this is a software engineering field of an eternal key topic. Over the past few decades, the International Software engineering community has made great strides in software architecture

"User Guide" should include
A few days ago, a few former colleagues came to my home to play, during which we discussed the current popular software architecture. Most of these colleagues are currently working with software architect engineers, and some want to grow into software architecture engineers.
1.1 Agent-Oriented Software Architecture
The basic idea of Agent-Oriented is to start from the human, things, and the environment in the real world, and think that the attributes of things, especially the dynamic characteristics, are largely influenced by the people and environment closely related to them, emphasize the interaction between understanding, thinking, and objective things and their environments
The last time I had the honor to introduce the software architecture design "Seven kinds of weapons", for this "Seven kinds of weapons" is a long process of cultivation, in addition to the need for continuous learning theory, principles, but also constantly in the software architecture design work to practice, and such
Several phases of software architecture development
1. Basic research phase (May 1985 ~ 1994)From 1960s to the middle of 1980s, software system designers were used to describing the system structure using graphic lines without uniform format and semantics. Of course, this is a very intuitive and understandable subconscious way to express the design system. Altho

Architecture design is similar to a workflow, it is dynamic, this is not like the architectural design, it can be completely determined at the beginning, the architecture is accompanied by the whole project process, there are two specific operations to ensure the correct completion of the architecture de
