Java Project for Beginners

Introduction of Projects

Business process outsourcing (BPO) is a subset of outsourcing that involves the contracting of the operations and responsibilities of specific business functions (or processes) to a third-party service provider. Originally, this was associated with manufacturing firms, such as Coca Cola that outsourced large segments of its supply chain. In the contemporary context, it is primarily used to refer to the outsourcing of business processing services to an outside firm, replacing in-house services with labor from an outside firm.

BPO is typically categorized into back office outsourcing – which includes internal business functions such as human resources or finance and accounting, and front office outsourcing – which includes customer-related services such as contact center services.
BPO that is contracted outside a company’s country is called offshore outsourcing. BPO that is contracted to a company’s neighboring (or nearby) country is called nearshore outsourcing

System Design Diagram

There are two types of system diagram and that is:

  • Static Diagram

  • Dynamic Diagram

Static Diagram

Java projects CLASS DIAGRAM

Class diagram is used to model the structure of a software.

Contents:

Class, interfaces , collaborations, relationships, note, grouping things, annotation things.

Structural things: classes
Annotation things: Note
Relationships: Association, Generalisation, Realisation, Dependency

OBJECT DIAGRAM

Object diagram models the instance of classes from the class diagram. Object diagrams represent the static part of the system. Contents: objects, links, annotation things, grouping things

COMPONENT DIAGRAM

Component Diagram models the Physical aspects of a system. A component diagram represents the static part of a system.
Contents:
Component, interface, relationships, and it also contains Grouping things, annotations things.

DYNAMIC DIAGRAMS

1. USECASE DIAGRAM

Usecase diagram is used for modeling dynamic aspects of a system.
It specifies what the system does.
Contents:
Usecase, actors, relationships, annotation things, grouping things, constraints, tagged values.
Actors: bpo org, client.
Relationships: unidirectional association

2) INTERACTION DIAGRAM

An interaction diagram is used to design the dynamic aspects of the system.
Contents: objects, links, messages

Sequence diagram:

Sequence diagram is one of the two interaction diagrams. It emphasizes on time ordering of messages

Collaboration diagram:

Collaboration diagram gives structural organization of objects

3) ACTIVITY DIAGRAM

The activity diagram is similar to the flow chart. It represents the flow of execution from one activity to another activity.
Contents:
Start, end, action, branching, fork, join, transition, swimlane.

4) STATECHART DIAGRAM

A statechart diagram is a state machine focussing on the flow of control from one state to another state.
Contents:
initial state, final state, state , transition.

SYSTEM IMPLEMENTATION:

Modules:

Creating credentials:

If the user wants to hire (or) work then he has an account, so he must do registration. So the user has to register their account in the given form, so the user can make hire (or) work will be happening in the bpo.

Upload (or) posting the project

If the user wants to post the project into the bpo, they must select hire when they are login , So the user can post their project and the give whole project details to the bpo.Because who want work on project ,they design like that.

Browsing the projects

If the user wants to work on projects, they should select the project ,they select projects by browsing process.The user must create the project whatever project details provided by bpo.After completion of designing the project they send to bpo.

Feedback

Here feedback only gives the user who is selected hire, after delivering the project by bpo. They give feedback on how the work is.

Conclusion:

Overall, outsourcing seems to be an important trend. There are some cons to outsourcing, but I believe that it has helped us grow and compete in a healthy way, especially over in India. Outsourcing has increased globalization, and everyone gains when it comes to expanding into more markets. It also helps create jobs and compete given a competitive advantage. If it helps cut costs to outsource jobs to a country where the wages are cheaper, then that will help any company grow and eventually create more jobs. Indians seem to view the United States as what they want to become. Becoming more westernized is very
important to them.
