Systems development methods for databases, enterprise modeling, and workflow management

To develop a conventional CORBA(Common Object Request Broker Architecture)-based distributed object systenl, flrst the systems requirements must be analyzed in requirements analysis step and systems overall interface and details must be specifled and built using lOL(lnterface Defmition Language) in design step. However, there are not too many models available that can be used as a benchmark in specifYing the requirements and details of the CDO(CORBA-based distributed object) system. Conversion to lOL from requirements analysis step or prelinlinary design stage is a difficult task and an effective method for veriflcation oflDL is not currently available. In the light of unique features of distributed object system, lOL errors that occur in the beginning of software development become the main causes of errors for the systenl as a whole. This paper suggests SACC (Software Architecture-based CORBA Component) model as a solution to the problems mentioned above in specifYing details and VerifYing CDO system. SACC model uses SCI (SACC Converted lOL) algorithms to be converted to lOL. SACC model utilizes software architecture approach. SACC modeling method uses CTL (Computational Tree Logic) to verifY CORBA system that is specifled by SACC model. In conclusion, SACC modeling method is proven effective in specifYing details and VerifYing the CDO system. Furthermore, it helps progranmlers to effectively convert to lOL, which is highly reliable.

Framework Oriented Software Development and its Challenges

The Object Oriented software development methodologies that are currently in use assume that all software components are to be developed from scratch. Software solutions providers and software consulting houses have always had a strong business interest in utilizing made to a pattern (standard) software products instead of developing software solutions from scratch. Rapid (and low risk) customization of their products has been their ultimate goal.

Resource Object Data Manager: Structured Approach to Systems and Network Management

Operational management of business computer systems and computer networks was not long ago performed by an operator or a team of operators who interacted with consoles displaying status messages. in such a set-up each system component independently resolved its own set of notices, identifying conditions needing attention.

Implementation of Project Management Systems Through Prototyping

This paper considers implementation of project management systems through the use of prototyping.

Planning Implementation Steps for Co-Operative Processing Systems

Co-operative Processing (COP) is a method of processing in which communication is an integral part of the mechanism of executing an application. COP processing model permits the application to be broken into pieces, to be executed on diverse hardware platforms, in order to derive the benefits of each. In this paper we discuss primary planning factors required to successfully implement COP applications.
