of the system architecture, but is not used by other importantThe function covered by case. 2. consider all aspects of the software architecture from various perspectives. The architecture design of the software must take into account all aspects. Based on the domain model, key requirements, and system constraints est

Toward ASP. NET architecture design-Chapter 2: Design Test code (previous) TDD is used as an example for two reasons: 1. TDD indeed presents the design ideas; 2. compared with DDD, TDD is easier to use and the learning curve is not that steep. I would like to reiterate that this series does not describe TDD, but uses

object of the operation of the instance.Fine granularity: Represents an instance-level, where an instance of a specific object (the instance of objects) needs to be considered, and, of course, fine-grained is considered a particular instance after the coarse-grained object class is considered. 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

description, parameters, details, all written to a static page, without the application of logical processing, no need to access the database. You do not have to deploy dynamic servers and database servers. Network bandwidth for the lease of the second kill activity Because the second kill new network bandwidth, must and the operator re-purchase or lease bandwidth. In order to reduce the pressure on the se

" indicates a set of services located between two layers for communication. To put it bluntly, more and more people think that "services" are not just code that can process requests. One of the main reasons for this situation is the increasing popularity of service-oriented and service-oriented architecture SOA. Service-oriented is a business design method consisting of a series of interconnected services.

data of an Access Control Server. The figure shows the entire access control system solution: an ACS server, a reader, and a database used to store data ). In addition, the ACS Server communicates with the card reader through RS485, while the ACS server uses TCP/IP to communicate with the database. Logical architecture The logic

, you can consider the PM mode. in WPF, this mode is also called mvvm. Summary In fact, the presentation layer is no less important than the business layer and data access layer. The presentation layer without intermediate core behaviors is useless even if it is dazzling. However, without the combination of the presentation layer, even a powerful middle layer cannot meet user needs. Related blogs: . Net enterprise-level application architecture

abstracted into the controller (Controller), models (model), view three modules, to achieve the business logic layer, the database access layer and the user interface layer in the separation between each other while still maintaining a loose coupling relationship, Increased flexibility and scalability. Our common C/s architecture, b/S architecture, N-tier

Introduction:We have discussed four process models for agile architecture design. In this chapter, we will summarize these four process models, the relationships between the four persons and the Agile Methodology characteristics embodied in the model are discussed. Through the description in this chapter, you can have a better understanding of the previous content. Focus of the four models I classify fo

, in fact, the introduction and implementation of this application event is not very reasonable. It needs to aggregate the root event to record the events that have occurred when a domain event occurs, then, when the warehousing completes Object Persistence transaction commit, these domain events are converted into application events and then sent to the event bus. There are two problems: first, it violates the "single responsibility Principal" principle of object-oriented

Part 1 of this series first checks the project time and progress, and then when we enter the architecture, design, data modeling, and prototyping, we are already refining the process in the next phase.
