澳洲会计学论文代写:SSADM

SSADM是一个特定的实现,建立在不同的学校工作的结构化analysisA和开发方法,如彼得Checkland是软系统方法论,拉里·康斯坦丁是一个结构化的设计,爱德华Yourdon是Yourdon结构化方法,迈克尔·杰克逊是杰克逊结构化编程,和Tom DeMarco是结构化分析。

面向对象数据库做出的承诺减少维护、代码可重用性,现实世界建模和提高可靠性和灵活性。然而,这些只是承诺,在现实世界中一些用户发现面向对象的好处不是他们最初相信一样引人注目。例如,isA代码可重用性?有些人会说他们可以重用的面向对象的代码创建一个系统,但很多人说没有更多的代码可重用性面向对象系统比传统的系统。一个代码可重用性是一个主观的东西,在很大程度上依赖于该系统是如何定义的。面向对象的方法确实给能够减少一些主要与系统相关的费用,如编程代码的维护和开发。这里有一些面向对象的方法的好处。

SSADM is one particular implementation and builds on the work of different schools of structured analysis and development methods, such as Peter Checkland’s Soft Systems Methodology, Larry Constantine’s Structured Design, Edward Yourdon’s Yourdon Structured Method, Michael A. Jackson’s Jackson Structured Programming, and Tom DeMarco’s Structured Analysis.

Object-oriented databases make the promise of reduced maintenance, code reusability, real world modeling, and improved reliability and flexibility.  However, these are just promises and in the real world some users find that the object-oriented benefits are not as compelling as they originally believed.  For example, what is  code reusability?  Some will say that they can reuse much of the object-oriented code that is created for a system, but many say there is no more code reusability in object-oriented systems than in traditional systems.  Code reusability is a subjective thing, and depends heavily on how the system is defined.  The object-oriented approach does give the ability to reduce some of the major expenses associated with systems, such as maintenance and development of programming code.  Here are some of the benefits of the object-oriented approach.
