J2EE is mainly used for main-scale computing in commercial sector
Why do I need the Enterprise Edition of Java Platform? J2EE is mainly used for main-scale computing in commercial sector. If any company ventures into competition in business world, it builds a user-friendly e-commerce website using J2EE multitier architecture.
There are many application development processes being used however the most common is RUP (Rational Unified Process). RUP provides a disciplined approach to assigning tasks and responsibilities to different roles. Its main objective is to construct high-quality software within a deterministic time-span and budget.
There are eight simple steps that’ll help you building a kickass stuff of the available resources:
STEP 1 : Requirements Analysis
This is the first phase of the software development life cycle. Here we analyze the purpose for creating our software. We gather relevant information using surveys, feedbacks, and interviews and brainstorming sessions to classify the collected information into two categories viz functional requirements and supplementary requirements.
STEP 2 : Object oriented analysis
In this phase we use various state diagrams of UML to represent our ideas in an objective format, carefully eliminating the technical details which may change over a period of time.The first two steps are not J2EE specific; they are generic however these two mark the inception of other important steps about to follow.
STEP 3 : Architecture Specification
To lay down architecture for a project is like creating its blueprint keeping in mind all the parts and components. Architecture can be divided into two- enterprise and application architectures.
STEP 4 : Object Design
A detailed design effort should address classification of all classes including the necessary implementation attributes, their detailed interfaces and pseudo code description of the operations.
STEP 5 : Implementation
The components should be carefully and patiently implemented step-by-step so as not to trigger any unwanted complexity.
STEP 6 : Validation
The validation process occurs both in the development and production environments.
STEP 7 : Assembly and Deployment
STEP 8 : Operation and Maintenance
