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 (
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 answers:
1. The database structure is not complex and there is no need to use
Since UML (Unified Modeling Language) is often used in development, especially in the OOAD stage of software development, it is particularly important to understand and use UML. Before starting with UML, let's review the main features of OOAD and OOP.
OOAD: The process of analyzing and designing software systems based on object-oriented methodology. It includes the OOA analysis phase and the Ood design phase. The analysis stage mainly solves the prob

The software engineering field has made unprecedented progress from 1995 to 1997, and its achievements exceed the total achievements in the software engineering field over the past 15 years. One of the most important and epoch-making achievements is the emergence of the Unified Modeling

Dimension Modeling Method
Dimension modeling organizes information into structs, which typically correspond to the query methods that analysts want to use for data warehouse data. How much food sales were in the northwest in the third quarter of 1999. Represents the use of three dimensions (product, geography, time) to specify the information to be summarized. Star mode is widely used, in order to do a lot
Preface
I wrote an article in the field of system modeling, which was written with an uneasy mood and did not dare to insult the thinker in this field, becauseGood working ideas/models in specific scenarios may fail badly in other scenarios. If there is a commonly used method/mode, the software will only provide support for this method/mode. Why bother?
Before talking about complicated time modeling cases,
confirmation, preferably with the user representative to confirm the signature.(2) "Review requirements Document" Activities, can not be omitted, the need for system analysis, designers to fully understand, analyze the requirements, confirm that the requirements analysis described clearly, and do not go beyond the scope.(3) "Create and publish a requirement baseline" activity, which solidifies the requirements and requires the creation of a demand tracking matrix.Next, we will focus on demand a

Note the text I mentioned above: "The uml2.0 draft Specification has been adopted ." Indeed, the specifications are still in the draft State, but the key is that the draft specifications have been adopted by OMG, which is an organization that uses them until the new standards are quite reliable.

First, we will refine the n in 1 to n. What is the magnitude of n? How many to dozens? Or how many to thousands? Or thousands?

For example, each Person has multiple addresses. In this case, we use the simplest embedded document for modeling.
