In emstudio, the concept and content of static modeling come from the UML standard. Therefore, the design capability of static modeling provided by emstudio can fully meet developers' design requirements. However, compared with the UML standard, static modeling in emstudio has two different characteristics:
1.The concepts of classes and entities are consistent.
Overview
In this ever-changing era of object-oriented application development, it is increasingly difficult to develop and manage high-quality applications within a reasonable period of time. In order to face this challenge, a general object model Language (UML) that every company can use is developed ). UML is a blueprint for the information technology industry and a method to describe the system structure in detail. Using this blueprint, we are increasingly easy to establish and maintain syst

Modeling
Modeling(Modeling)It refers to the establishment of an abstract method of objective things to characterize things and gain an understanding of the things themselves. At the same time, this understanding is conceptual and these logical concepts are organized, an easy-to-understand expression

I have been doing research on foreground detection recently. At the beginning, I mainly made some engineering applications. I have made a lot of effort to solve engineering problems, I have also read many recent articles at home and abroad. I have always wanted to make a conclusion, dragging on, but after all, I wrote this extremely unsuccessful summary.

Introduction: The first two blog posts (Database DesignStep by step (5)-understand user requirements and database designIn step by step (6) -- extract business rules), we analyze database requirements, focusing on two topics: 1. understanding user requirements; 2. Extracting business rules. After the requirement analysis is complete, we will enter the conceptual data modeling stage. This article uses the "Basic Object link model component" and "Advanc

StereotypesPatternthe UML provides a language for Structural things, behavioral things, grouping things, and notational things. These four basic kinds of things address the overwhelming majority of the systems you " ll need to model. However, sometimes you ll want to introduce new things that speak the vocabulary of your domain and look like primitive buildi ng blocks. UML as a structural thing ﹑ Behavioral Things ﹑ group things and annotate things provides a language. These four basic

Prior to understanding the requirements of the introduction of engineering and the capture of requirements, respectively, the difficulties in capturing requirements.

in a controlled manner to convey your intentions.Modeling is all about communication. The UML already gives all the tools are need to visualize, specify, construct, and document the artifacts of a wide RA Nge of software-intensive Systems. However, you might find circumstances in which'll want to bend or extend the UML. This happens-human languages all the time's why new dictionaries get published every year), because no static language can ever is sufficient to cover Everythin G You'll want to
