The methods for modeling SQL Server four data warehouses are mainly grouped into the following four categories. The first class is the three-paradigm modeling of relational databases, and we usually use the three-normal modeling method to build various operational database systems. The second type is the three-paradigm Data warehouse model advocated by Inmon, w

After reading this article, you may feel a little bit about NOSQL data structures. My feeling is that the relational database wants to do a good job of consistency, integrity, indexing, crud, NoSQL doing only one thing, but sacrificing a lot

As a matter of fact, I never wanted to write or recall the nearly one-year life of mathematical modeling. It was so difficult that I made many first decisions, I still feel a little scared. If I want to participate in another mathematical modeling, I think I will firmly answer"N0". The Association for Science and Technology of the Software Institute reorganized several sub-societies, including mathematica

Using the [iconix] method to practice blog design 2 [case modeling] In the previous article, we learned about and implemented Domain Modeling. In other words, we had a good start, at least the developersThe software to be developed has a preliminary understanding and a glossary can be used for communication.This chapter will further elaborate on the use of the iconix Method for practical case

1. Application background1.1 Resolved issues1) IT systems for large enterprises will be tested in their test environment beforehand for each application upgrade. How to ensure the validity of the test? How can the results of the test be inferred from the performance of the production environment?2) as resource usage grows, resources such as CPU, memory, hard disk, I/O, and so on interact with each other and have potential associations. How do you gain insight into its relevance to guide your bus

our familiar domain, it is often found that in another adjacent field, there are many problems, ideas, ideas and knowledge are interlinked, as if the initiative opened a door, to explore the new "adjacent possible" provided the conditions. In fact, there are a lot of small creative ideas in this book that I was inspired to read in the non-test theory books. For example, the 5 main chapters of this book "Kym" "TCO" [8] "Modeling (

Domain-driven design methods start with modeling. They mainly include information modeling, behavior modeling, and UI modeling; Information modeling is the beginning of a domain-driven design. Information Modeling partitions info

Object-Oriented Analysis and Design have suddenly emerged, software Enterprises are transitioning from process-oriented to object-oriented. On the other hand, rose embodies the advanced design ideas of Unified Software Modeling (UML), and can express various design ideas in a concise and effective manner through a unified set of graphical symbols. Of course, the commonly used UML modeling tool Rose is well

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 rational, booch, Rumbaugh, and Jacob bson.
