IntroductionAs developers creating data-driven Web applications, we 've all written more than our fair share of SQL statements. if I had a nickel for every SELECT statement or UPDATE statement I 've written in my six years as a Web developer, I 'd be a rich man. despite the familiarity with SQL that extends Web developers have, one of the lesser known SQL tools is the CASE statement. the CASE statement is a

Uml-unified Model Language Unified Modeling Language, also known as standard modeling language. is a language used to visualize modeling software-intensive systems.There are three main models in UML system development:Functional Model: Display the function of the system from the user's point of view, including use case diagram.Object model: Using the concepts of object, attribute, operation and correlation to show the structure and foundation of the s

Commonalities: the common information is extracted from the existing use cases. As a separate use case, different methods are used to reuse this public use case, to reduce the workload of model maintenance.1. Include) Inclusion relationship: Use inclusion cases to encapsulate a group of similar actions (behavior fragments) that span multiple use cases, so that multiple base use cases can be reused. Use

Turn from: http://blog.csdn.net/icu/archive/2006/03/07/617638.aspx preface Now that RUP is at its zenith, demand analysis is the first step and can be seen as a prerequisite for advanced system analysts, so if you use object-oriented analysis techniques to describe the requirements. In a demand analysis process, there are project descriptions, risk analysis, use case diagrams, and descriptions, which are part of the project recommendations. One of the

A lot of people in the analysis of demand, the use of the East pull gourd West pull Scoop way, listed a lot of demand points, but when you read, you still do not know what to do!! ----written in front.Use cases, English names using case, English and Chinese are very good understanding, because everyone is so used, we will not pursue the name of the problem, as long as we know "use cases are used to describe the requirements of the process", that is: d

Switch case is a qualified data in js, which is much simpler than if else. Next I will introduce my understanding of js switch case. In the if Condition Statement, only one logical condition can exist. if multiple conditions exist, you can use nested if statements to solve the problem. However, this method increases the complexity of the program, reduce program readability. The switch flow control statement

The automated regression test case evaluation criteria try to define different dimensions to evaluate the advantages and disadvantages of automated cases, which serves as the basis for subsequent evaluation and discussion of the test framework, test technology, and test case writing mode. So what is a good automated regression test case? In short, it is a

What is use case The writing of case description documents is a reflection of the deep understanding of user requirements by system analysts. It is an important basis for later time sequence diagrams and actual development. It can also be used as a basis for project estimation, as well as to measure the efficiency of developers Based on UC complexity and development cycle. Therefore, the writing standard o
