CAD's full name is "Management Software Computer Aided Design", which means "Management Software Computer Aided Design" in Chinese. It refers to the use of computer software to design management software on a graphical development interface and the process of designing management software. Structure, data structure, and finally the process of generating independent application management software through automatic data loading and analysis of computer software systems.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
CAD, the full name of Management Software Computer Aided Design (MS-CAD), refers to the use of computer software to design management software on a graphical development interface, through The process of designing the process structure and data structure of management software, and finally generating independent application management software through automatic data loading and analysis of the computer software system. Maximize the "flexible adjustment" capabilities of information systems.
CAD refers to the use of computers and graphics equipment to help designers carry out design work. In design, computers are usually used to perform a large number of calculations, analyzes and comparisons of different solutions to determine the optimal solution; various designs Information, whether numerical, textual or graphical, can be stored in the computer's memory or external storage and can be quickly retrieved;
Designers usually start a design with a sketch and turn the sketch into work The heavy work of drawings can be left to the computer; the design results automatically generated by the computer can quickly produce graphics, allowing designers to make timely judgments and modifications to the design; the computer can be used to edit, enlarge, reduce, pan, and edit graphics. Copying, rotating and other related graphics data processing work.
is a popular auxiliary drawing software system in China. It is widely used in civil construction, decoration, urban planning, garden design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry, chemical industry and many other fields. .
The representative product in the field of management software CAD is Yigo management software CAD (YMS-CAD) developed by Brocade Information.
It refers to using Yigo’s graphical design tool to help software designers and on-site implementation consultants design and manage software prototypes, automatically generate application systems, and ensure the robustness and efficiency of the application system.
Features:
Reuse of standard management models: organizational model, business model, data model, control model, optimization model.
Users can interact with the computer in a graphical way, and the WYSIWYG description prototype system forms the management script of the target system. The running system is automatically generated based on the management script. Generate corresponding operating systems according to the requirements of different operating environments (hardware devices, operating systems, databases, middleware, etc.).
Upgrade and maintenance of system business functions: User maintenance of the system is the maintenance of management scripts; upgrade of system business functions is the modification of management scripts.
Upgrade of system technology and operating environment: When users need to change the system operating environment, their original management scripts can be automatically parsed again to generate a system that adapts to the new operating environment. Upward compatible.
Architecture independence: hardware independence, operating system independence, database independence, middleware independence, and client independence. Covers various management information categories (ERP\CRM\SCM\HR\OA\EIP\EC, etc.) required by enterprises (manufacturing, circulation, service industries), governments and administrative institutions, and can be set according to users The management system goal is to establish an integrated organic ecological management information system. And the functions of the system can be adjusted and expanded at any time to form a growing ecological software system.
Breaking away from traditional software hard integration and hard upgrades: The segmentation and segmentation of software modules imposed on users by software manufacturers makes system maintenance, upgrades, and integration extremely difficult. Hard upgrade means that the customer needs to purchase a new software package from the software manufacturer for a certain business expansion, or ask the manufacturer to modify the system code. Hard integration refers to the integration of various modules from different manufacturers through a large number of secondary development interfaces.
Compared with traditional software development methods, the efficiency is improved several times or even dozens of times, which shortens the software implementation period. The robustness of the system is unmatched by traditional development methods.
Function:
Function library: management particles, reusable and subdivided management logic, including molecules, molecule sets, and optimization An algorithm for managing transactions, often referred to as a business component, is built into a function library.
Business Application Framework (YAF): system construction specifications, group organizational structure, industry business framework, and financial business mapping rules.
Best management model library: application of classic standards of the business modules involved, such as distribution management, group finance, group procurement and other businesses that can independently complete a certain management transaction Model.
Design tools: basic data management (dictionary), form business flow design, approval control flow design, management workflow design, interface design.
Extended information:
CAD software is a drawing software. It can draw complex engineering drawings instead of simple lines or icons. Its drawing function is very powerful. Therefore, if you draw mechanical drawings, architectural drawings, electrical drawings, etc., you generally choose CAD. CAD There are three types of drawings, plan view, axonometric view and three-dimensional view.
Uses of CAD software:
1. CAD software is used for engineering drawing: construction engineering, decoration design, environmental art design, hydropower engineering, civil construction, etc.
2. CAD software is used for industrial drawing: precision parts, molds, equipment, etc. ,
3. CAD software is used for clothing processing: mainly used for clothing pattern making.
4. CAD software is used in the electronics industry: mainly used in printed circuit board design.
5. CAD software is widely used in many fields such as civil construction, decoration, urban planning, garden design, electronic circuits, mechanical design, clothing, shoes and hats, aerospace, light industry and chemical industry.
According to different models, CAD systems are generally divided into two-dimensional CAD and three-dimensional CAD systems. Two-dimensional CAD systems generally regard product and engineering design drawings as a collection of geometric elements such as "points, lines, circles, arcs, text...".
Any design expressed in the system becomes a geometric figure, and the mathematical model it relies on is a geometric model. The system records the geometric characteristics of these graphics elements. Two-dimensional CAD systems generally consist of graphics input and editing, hardware interfaces, data interfaces and secondary development tools.
The core of the 3D CAD system is the 3D model of the product. The three-dimensional model is a three-dimensional model that represents the actual shape of the product in a computer. The model includes various information about points, lines, surfaces, and bodies of the product's geometric structure. The description of computer three-dimensional models has experienced development from wireframe models, surface models to solid models. The geometric information expressed is becoming more and more complete and accurate, and the scope of "design" can be solved in a wider range.
