1.Scope
This report will define the high level design and technology decisions of the Online Carpooling System.
This sdd defines and describes the use of each view, the architectural constraints of the system, the functional requirements with a significant impact on the architecture, use-case realization, concurrency aspects, the layers and subsystems of the application, performance issues and constraints.

2. References
[14] Software Engineering Standards Committee of the IEEE Computer Society, “IEEE Recommended Practice for Software Design Descriptions”, IEEE Std 1016-1998.

3.Definitions

Car-Pooling: Carpooling (also known as ride-sharing, lift-sharing), is shared use of a car, in particular for commuting to work, often by people who each have a car but travel together to save costs and in the interest of other socio-environmental benefits. [1]

4. Considerations for producing an SDD
4.1 Software life cycle

4.2 SDD within the life cycle
In the design part of our waterfall model life cycle we define our sdd. After determining the requirements and specifications as the cycle goes through design part we make a prototype of our software design. Before implementation it is vital to design the software to be more controlled on coding part. As the cycle shows if there is a problem in maintanence about the design part we can go back and fix it.

4.3 Purpose of an SDD
The purpose of this sdd is to define and describe the use of each view, the architectural constraints of the system, the functional requirements with a significant impact on the

    The first step is to identify the major software components of the system being developed. Software systems are divided into four major functions. Data storage in an Information System stores the data or file. Data Access Logic is managing needed to retrieve the data. Application Logic is the processes or activities that are executed. The final function is the Presentation Logic function which is the presentation of the information and the user interface. Knowledge of the functions is vital in the design process and the data flow diagrams (DFD).…

    The system development life cycle (SDLC) starts when a project is planned for the implementation of an information system. Executives of the organization make a decision for a new system or replacing or upgrading an old system and the project begins. According to Curry, McGregor, and Tracy (2007), “For a development project to be successful, the people involved in the project must have a detailed plan to follow.” The entire process in which the building, deploying, using, and updating an information system is known as the SDLC.…

    The Unified Modeling language (UML) was released by the Object Management Group (OMG) in the effort to provide a standardized design language to build and develop computer applications. The purpose of the design language is to allow IT professionals to distribute system structure and design plans in a comprehensible graphical manner, similar to blueprints of a building. Modeling is an important part of software projects, large and small. With modeling, the software development team are better able to work with the end-user in providing a visual program design. Surveys reveal that the development of large software applications have many impediments and have a large probability of failure. Modeling provides a greater opportunity for success in the development of software applications. (Introduction to OMG's Unified Modeling Language)…
