When designing databases, many people prefer to use the word document format to design database structures before creating physical databases; there is very little Database Design Using database modeling tools. If you ask people who are unwilling to use database modeling tools, I think they will give you the following

A lot of people in the database design, still prefer to use Word document format to design database structure, then the creation of physical database, and the real use of database modeling tools for database design is very few; If you interrogate people who don't want to use database modeling tools, I think they will u

express the relevance between businesses. At this stage, I suggest you refer to the 3nf modeling method to express the attributes of an object and the relationship between the object and the object. For example, at this stage, we can use modeling tools such as Erwin to create a 3nf-compliant relational data model. 4.

convenience of the perfect combination of Rational rose and the GUI in the Microsoft Visual Studio Series tools makes it a preferred modeling tool for most developers, and Rose is the first tool in the market to provide support for UML-based data modeling and web modeling.

Comparison of UML modeling tools Visio, Rational Rose, and powerdesignRose is a design tool born directly from the Development of UML. It was designed to support UML modeling. Rose did not support database modeling at the beginning, however, the database modeling function ha

software companies and development teams have started or have adopted rational Rose for the analysis, modeling and design of large-scale project development. From the perspective of use, Rational rose is easy to use, supporting complex systems with multiple components and multiple languages, and using bidirectional engineering technology to achieve iterative development; team management features support large, complex projects and development teams w

Since the formal release of UML in 1997, a large number of commercial UML modeling CASE tools have appeared. This provides us with a lot of options and requires us to select the correct UML modeling tool to better adapt to our business and software application development needs, do a lot of research to achieve the best ROI. In this article, we will compare the UM

Comparison Between Rational Rose and powerdesigner modeling tools I,Their originsAs the world's two most famous case tools, rationalRose and powerdesigner are well known. Rose was the fist product of rational, the world's largest CASE tool provider at that time. The UML modeling language isInvented by three giants of r

following order: First, compare the classic and common data Warehouse model, and analyze its advantages and disadvantages. The basic concepts and related theories of dimension modeling are introduced in detail. To get a better understanding of what dimension modeling is, I'm going to simulate an electric arcade that we all know well, and use the theory we've tal

Control: Controlling object, which is used to represent the business logic, the Division of labor coordination of the responsibility object, the use of control mode analysis design is much used.

I recently found a good book on Data Modeling in a bookstore-data modeler's workbench: tools and techniques for analysis and design ), author Steve Hoberman. After a rough review, I feel that this book is indeed worthy of the praise of the translators and foreign experts: "This book is full of techniques and Techniques

IntroductionThe evaluation of several modeling tools was highlighted in the previous blog, and SQL Power architect was selected as the final modeling tool, and the Oracle Data Modeler support Vertica was also studied during the evaluation process, although the eventual abandonment of Oracle

advantages of dimension modeling can be summarized as follows: A the dimension modeling is a predictable standard framework . Allows database systems and end-user query tools to generate powerful assumptions about the data, which work primarily on performance and performance. b The predictable framework of the star jo

XML columns in the table, whether they are stored in rows or stored in rows, and occupy space. Granularity of XML data The granularity of XML data stored in an XML column is critical for locking and updating attributes. SQL Server uses the same locking mechanism for XML and non-XML data. Therefore, row-level locking causes all XML instances in the correspondin
