At the beginning, the author explains why modeling is required. Next, he describes four key structural analysis model tools, which are well-known.DFD(Dataflow digoal),ERD (entity relationship digoal),STD(State Transition Divisor),SC (structure chart) The following is a simple description. 1. DFD (dataflow digoal) DFD diagram is used to describe the data processing process. Includes: d

When the mysqld process is started, specify the five common tools to be compared using the -- log-slow-queries [= file_name] Option.

Mysqlslowlog is a log tool used to record SQL statements that have been executed for a long time (beyond long_query_time seconds) to enable slow log.

product development process. In this article, we'll show you how to use Visual studio®team System development Edition or VisualStudio Team Suite to identify performance bottlenecks in your application. You will be introduced to the Visual Studio parser by walkthrough a sample performance Survey. Note that although we are using C # in this article to write code examples, most of the examples here are equally valid for native C + + and Visual Basic® code.

SQL analysisSQL analysis (SQL Analyze) is a tool that integrates the performance analysis of specific SQL statements in Enterprise Manager. The SQL statement that completes the same task, writes according to the different syntax, can obtain the different execution performance. Oracle SQL Analytics Tools provide intuitive visibility into the performance of SQL st

【Abstract] This article discusses the main features of this project and my work through an integrated circuit design-related software project, the specific methods and tools used in the project requirement analysis and the reasons for selection are discussed. Due to the special nature of the professional field of the project, the problems encountered in the demand analy
