performed on the frontend using Java script, and the legitimacy verification related to the business logic is performed on the business logic layer, you can use a centralized servlet to handle errors. "In Windows, we know that the boundaries of the layer-3 structure are different from those in Java.

processing. The legality verification related to the business logic is processed at the business logic layer. You can use a centralized servlet to handle errors. " In Windows, we know that the boundaries of the layer-3 structure are different from those in Java (this will be described in detail in the next article). We canIt is very convenient for the display layer to directly manipulate data. Therefore, the Architecture Vision descriptions in Window

Architecture : This part of the thinking focuses on "overhead" and "contention," so the goal of the architecture is to reduce overhead and avoid expropriation.Data Schema : The data distribution scheme is a difficult point, usually with the help of 6 strategies.3 Application principles: grasp the characteristics of the system, determine the distribution strategy (appropriate principle), different distribut

previously shared a point of view that the optimization of the "architecture design from the business is rogue" architecture should also be targeted at the business. The database layer The browser intercepts 80%, the site layer intercepts 99.9% and performs page caching, and the service layer implements a Write Reques

Multi-layer architecture design preface and architecture design preface. Multi-level architecture design Preface: because php native is designed to assist in the generation of HTML, code and HTML code are mixed and written togethe

and knowledge (I have never thought too well about the classification standards, so I said my own experience and knowledge), I divided data into two categories: landing data and not landing data. Landing data: persistent data, which is usually stored on a hard disk or another persistent storage device. For example: images, system logs, data displayed on the page, and data stored in the relational database, there must be a fixed carrier for la

process is unidirectional, as shown in.The general purpose of one-way hash encryption is the encryption of the user's password, so that the password is not reversible to the database, even if the database information leaks, the attacker can not know what the original password is.The common one-way hashing algorithm has MD5, SHA and so on.5.2 Symmetric encryptionThat is, both encryption and decryption use t

Web API application architecture design analysis (1), api Architecture Design Web API is an application interface framework that can build HTTP services to support a wider range of clients (including browsers, mobile phones, tablets, and other mobile devices). ASP. NET Web API is.. NET Framework. This article mainly in

accumulation and code reuse of the team, sometimes for experience, sometimes it is to work out reusable frameworks ). These can also be called goals. Therefore, when designing an architecture, you must first determine your purpose and consider things that are helpful to the purpose.Scott W. ambler mentioned in his article a story that he experienced personally. During the architecture

Introduction to android Architecture Design and android Architecture Design So far, android development has no accepted or unified development framework on the network or in the community. Many frameworks are based on method encapsulation. Today, I am talking about my understanding of android development over the past

easy to imagine, the biggest problem is how responsibilities are assigned. On the system architecture design of the biggest problem, in fact, is the allocation of responsibilities, allocation of reasonable, the implementation will be very flexible, the contrary will make the structure is very chaotic.The life cycle of software can be summarized into four basic processes, analysis,

, the intermediate calculation process cannot record the result directly, but the system rollup must be dispatched. (Transaction, crash-proof) the intermediate Task module considers the crash recovery of the transaction. 8. Computing systems and external management system can be further abstracted into computational units. 9. The coupling of dispatch system and business should use database isolation. 10. Configuration information should also be embodi

experience, a database-based system architecture, how many data tables will be there on how many pages of architecture design documents. For example, a medium database application system usually contains about one hundred data tables. Such a system
