to design the HBase primary key in the HBase authoritative guide. There is no methodology like programming design patterns that can be followed at the model architecture level. When comparing different NoSQL databases, various metrics, such as extensibility, performance, and consistency, are often used in addition to features. Since these indicators are often used in the original sense of NoSQL, they are d

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

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.

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
