Visual Modeling Software ApplicationsNote: Some functions may not be provided in the publicly published Visual Studio. NET Beta 2.For customers who build complex distributed applications, one of their challenges is whether the application architecture and requirements can be successfully communicated to a wide range of group members. This challenge becomes more challenging when you consider loosely joined X

3d printing technology is an advanced manufacturing technology which is gradually emerging in the the 1990s. 3D Printing--three-dimensional Printing, abbreviated as 3DP. Also known as three-dimensional printing or stereoscopic printing, was first developed by MIT in 1993. 3D printing technology is based on the computer three-dimensional design model, through the software layered discrete and numerical control molding system, the use of laser beam, h
After writing my first reading note, I read the one-week requirement engineering-software modeling and analysis, and felt that something had to be written down before it could turn out to be.Demand engineering has three main tasks: first, the requirements engineering must demonstrate that the software system will be applied to the environment of extreme objective
Demand analysis is a requirement engineering activity which is used to solve the need of obtaining information and developing the software system solution which needs to be established. Demand analysis occupies an important position in demand engineering. In the process of demand analysis, we need to constantly collate, analyze, pay attention to every detail, determine the boundaries of the system. Set up a good model, if you encounter new problems, t

Link: A) one-way Association: As far as chasing mm is concerned, many people seldom find her, but she is not uncommon. B) two-way Association: for husband and wife, a man can only have one wife, while a woman can only have one husband. C) Self-Association: Typically, in the menu, the sub-menu and the parent menu encapsulate the same data, but the menu class must have its own refe

# It is necessary to become a project manager. If you want to be quick but don't want to pay, it is better to worship Buddha. # This series of articles is written to people who want to become project managers but are willing to work hard. When we develop software, many people know that we need to model the target software to meet the development requirements. It is also a requirement to become a project ma

Recently read the "Demand Engineering-software modeling and Analysis" This book, this time I read the fifth part of the "demand management and engineering management", divided into three chapters, demand management, demand engineering process management, demand engineering project management.Requirement management includes maintenance requirement baseline, requirement tracking, control change, and requireme

Select Database System The persistence database layer can be a relational database or an object-relational database or an object database. From relational database technology to object database technology is an evolutionary process, object database technology is the intermediate stage of this evolution process, although the futur
external storage, and their lifecycle ends when the interaction completes. To make the interaction between classes simple and clear, the interface control class is only related to interface classes, use case control classes, interface control classes should not be related, interface classes rely on interface control classes, and interface control classes rely on use case control classes. The actions and properties of the interface control class can be defined when you design the sequence diagra
This paper mainly introduces the design process of use case model, first design use case model from system layer, then refine each use case of system layer recognition, design more detailed use case model. The use-case model is the starting point of the development process and drives the modeling process. The following is a case study of the use case model of office automation (OA) to explain the design process of the case model. The use case model in

UML is generally used in case-driven, architecture-centric, iterative, and incremental development. UML uses the following five views to describe the architecture of the software system: User Model View-use case diagram to describe system functions from the outside Structure Model View-class charts and object graphs, describing classes, objects, relationships between them, and other static structures to support the functional requirements of th
This semester we also learned the principles of compiling knowledge, summed up, a total of several steps:1. Lexical Analysis: The task is to convert the source program into an internal format;2. Grammar Analysis: The task is to determine whether the source program structure conforms to the language syntax;3. Semantic Analysis: The task is to ensure the semantic correctness of the source program;4. Intermediate code Generation: Converts the source program into an equivalent intermediate language
-oriented, the design process should be repeated with the user to discuss, fully understand the user's requirements, the use case map to the user interface, according to the needs of the user to the appropriate combination of use cases. There are two kinds of relationships between interface classes: One is the composition relationship and the other is the dependency relationship. A specific window is composed of many components, the window and the component is formed between the relationship, on
