Unified Modelling Language (UML) is a well-defined, easy to express, powerful and universally applicable modelling language. Its scope is not limited to supporting object-oriented analysis and design, but also supports the whole process of software development, starting with requirements analysis.The structure of UML: The structure of UML consists of the basic building blocks, the rules that govern how these building blocks are put together (the architecture) and a number of mechanisms that apply to the whole of UML.

that distinguishes object-oriented methods from other methods. Encapsulation: The unit of encapsulation in an object-oriented system is the object, and information can only be exchanged between objects through interfaces. Messages: Messages are the means of communication between objects, where one object requests a service by sending a message to another object. Polymorphism: Polymorphism means that the same operation can be interpreted differently when applied to different objects, and produce different execution results

Classes: A class is a collection of objects with the same properties and the same operations. Each class generally has instances; a class without instances is an abstract class. Inheritance: Inheritance is a mechanism by which different classes in a hierarchical association of a class share properties and operations. For two classes A and B, if class A is a subclass of class B, then class B is a generalisation of class A.

quality model has been adopted by China's national standards GB/T16260 - 2002 Information Technology Software Product Evaluation Quality Characteristics and Guidelines for Their Use. 2.8 Software Process Improvement Software Process Capability Maturity Model (CapabilityMaturityModel, CMM) and Capability MaturityModelIntegration ( CapabilityMaturityModelIntegration, CMMI)

models has two representations, namely, phased and continuous. 2.9 Object-Oriented Approach mainly examines the basic concepts of object-oriented, data hiding, UML and building blocks. 1) Basic concepts Object-oriented approach includes object-oriented analysis, object-oriented design, and object-oriented programming. Object: An object is a set of attributes and a wrapper for dedicated operations on this set of attributes. An object can typically consist of three parts

personnel, strategies, systems and procedures. 1. Function of proposed new system - objective 2. Analysis of existing system (business process) 1. Methods of risk identification: inquiry method (mind scenery method, interview method and Delphi method)

The first thing you need to do is to get a good idea of what you're doing.
