ParkingFinder.com is a type of e-business exchange that does business entirely on the Internet. The system connects parking space landlords and space tenants all over the world in an online market and manages the entire booking process and payments.

For a person to offer parking spaces (landlord), he/she must register with ParkingFinder.com. The person must provide a current physical address and telephone number as well as a current e-mail address. The system will then maintain an open account for this person. Access to the system as a landlord is through a secure, authenticated portal. 

A landlord can list parking spaces on the system through a special Internet form. Information required includes all of the pertinent information about the parking space, the asking price, and documents showing that the landlord has the right to rent the space. A landlord may list as many spaces as desired. Parking spaces listed by a landlord need to be verified that the landlord owns them, before they can be visible to the public. The system maintains an index of all parking spaces in the system so that tenants can use the search engine to search for parking spaces. The search engine allows searches of parking spaces by location. At the end of each month, a check is mailed to each landlord for the spaces that have been rented.

People wanting to rent parking spaces (potential tenants) come to the site and search for the space they want. When they decide to book, they must open an account with a credit card to pay for the parking space. They need to select the space they want to book, the time slot for the renting period and the vehicle license plate number. The system maintains all of this information on secure servers. The tenants can, if they want, enter their review and ratings of the parking space. The same functionality can be accessed through mobile app, which can be downloaded and installed from Apple Store and Google Play Store.

Dillon DQ1

The objective of systems analysis is to thoroughly understand the organization’s informational needs or requirements and to document those requirements in a set of specifications. Systems design is the bridge process that takes us from requirements to solution. The objective of system design is to define, organize, and structure the components of the final solution system (Satzinger et. al 2012).

  User-interface design is concerned with designing the interface that allows users to interact with the system. It includes designing screens, menus, buttons, and other visual elements that users see and interact with. System-interface design, on the other hand, is concerned with the interfaces between the system and other systems or components. It includes designing the protocols, formats, and messages used for communication.

Several diagrams developed during the analysis phase can be used for user-interface and system-interface design. Use case diagrams can be used for both. Use case diagrams show the interactions between the user and the system, which can be used to design the user interface. Use cases can also show the interactions between the system and other systems, which can be used to design the system interface.

  Sequence diagrams can also be used for both user-interface and system-interface design. Sequence diagrams show the interactions between objects or components, which can be used to design the flow of control in the user interface and the messages exchanged in the system interface.

  Finally, class diagrams can be used for system-interface design. Class diagrams show the classes and relationships between them, which can be used to design the data structures and objects used in the system interface.

  Overall, while user-interface design is focused on designing the visual elements that users interact with, system-interface design is focused on designing the interfaces between the system and other systems or components. The use case, sequence, and class diagrams developed during the analysis phase can be used to aid in both types of design.

Both the design types are sort of similar but at the same time, there are distinct variations between them. The architectural design on one hand is a type of rough and brief blueprint for a new system or an existing system. This type of design simply gives what the project is expected to present and what kind of taskings and functions this system is capable of demonstrating. This design doesn’t go in very deep into the details but gives an idea of the initial structure and outline of the system. It also gives a

Principles of Project Management:

The Need for Project Management

  • Standish Group CHAOS Report shows too many IT project fail (only 32% completely successful)
  • Reasons for failure
  • Undefined project management practices
  • Poor IT management and poor IT procedures
  • Inadequate executive support for the project
  • Inexperienced project managers
  • Unclear business needs and project objectives
  • Inadequate user involvement

    The System Development Life Cycle (SDLC)

    • There are two general approaches to the SDLC
    • Predictive Approach
    • Waterfall model
    • Assumes the project can be planned in advance and that the information system can be developed according to the plan
    • Requirements are well understood and/or low technical risk
    • Adaptive Approach to the SDLC
    • Iterative model (as see in this text)
    • Assumes the project must be more flexible and adapt to changing needs as the project progresses
    • Requirements and needs are uncertain and/or high technical risk

    Traditional Predictive SDLC

    • Earlier approach based on engineering
    • Typically have sequential Phases
    • Phases are related groups of development activities, such as planning, analysis, design, implementation, and deployment
    • Waterfall model
    • SDLC that assumes phases can be completed sequentially with no overlap or iteration
    • Once one phase is completed, you fall over the waterfall to the next phase, no going back
