Distributed system development al Affiliation Distributed system development processes Distributed system developmentprocesses are stages involved in the construction of the distributed system architecture. The distributed system development process begins with overall system partitioning, followed by network communication definition and then concluded with the implementation of its functions (Papadopoulos, 2009. This paper describes the features and components involved in the development processes for distributed system.

It will also propose the advantages and disadvantages of the same development processes for distributed systemsCommon Object Request Broker Architecture (CORBA)CORBA is an acronym for common object request broker architecture. CORBA is the standard software that supports distributed objects. It is a complex and a more difficult to learn software than any other communication infrastructure. COBRA offers a lot of functionality such as, programming language independency and the operating system.

On the other hand, CORBA possesses the binding power to arrange of standardized programming languages as a communication format (Papadopoulos, 2009). Among the advantages of CORBA process, is its level of maturity, CORBA developed by the Object Management Group and its standard is neither too lax nor too restrictive. CORBA does not endanger the interoperability of some products nor the portability and space for optimization. Therefore, it offers a real international tested and proven power, flexibility and performance.

CORBA offers a modularization facility to write objects in different programming languages that provide a service to users that do not require details of implementation of the object(s). CORBA also offers a facility that allows different clients to use the same interface thus working together transparently (Papadopoulos, 2009). CORBA’s disadvantages include its architecture complexity and specification which do not give a clear implementation details. It offers vertical features, which target some users and applications, but not all technology users thus insufficient (Papadopoulos, 2009).

Java 2 Enterprise Architecture (J2EE)Java2 Enterprise Architecture (J2EE) is a mainframe scale computing platform which made for large firms. It simplifies thin client tiered environment application development (Papadopoulos, 2009). It decreases the need for programming, and programmer education by enhancing the tier to perform many programming aspects automatically.Advantages of the Java 2 Enterprise Architecture (J2EE)The Java 2 Enterprise Architecture (J2EE) consists of a security model which protects data both in web-based application and also locally.

It is portable since it consists of a write once and Run anywhere technology. On the other hand, Java 2 Enterprise Architecture (J2EE) consists of full support for Enterprise JavaBeans (EJB) for program components delivery in an enterprise environment. It has enhanced security and deployment features, which supports the Extensible Markup Language. It also consists of application programming interface (API) which facilitates consistence for users without the need for graphical user interface (Papadopoulos, 2009).

Disadvantages of the Java 2 Enterprise Architecture (J2EE)The system does not guarantee reference implementation. The Java 2 Enterprise Architecture (J2EE) distinguished by compromise and consensus and it is not a perfect system.Conclusively, the Java 2 Enterprise Architecture (J2EE) facilitates a business to business framework for information interchange through extensible markup language (Papadopoulos, 2009).
