Study Notes

Systems Design and Analysis I

  • This course is about systems design and analysis.
  • A system is defined as a combination of interacting elements organized to achieve one or more stated purposes. It can also be viewed as a product of acquisition or as the provided services.
  • Analysis involves studying a system to determine how its parts (functions, components, or objects) relate to each other and to other systems. It's an investigation phase to specify user information needs.
  • Design defines the architecture, system elements, interfaces, and other characteristics of a system or system element. It's a process of defining the software architecture and resulting in a description of how the components of the system will function.
  • System analysis is a systematic investigation to determine the information requirements and processes of a system and its relationships to other systems.
  • System design is the process of defining the hardware, software architecture, components, modules, interfaces, and data to satisfy specified requirements.
  • Information systems perform tasks via a wide range of applications-programs supporting specific tasks or business processes. Each functional area of a business uses many application programs.
  • The main functions of information systems include carrying out high-volume numerical computations, providing communication, storing vast amounts of data, analyzing vast amounts of data, and automating business processes.
  • Interorganizational information systems (IOSs) connect two or more organizations. They manage operations, with supply chain management being a well-known example.
  • Computer-based information systems (CBIS) incorporate hardware, software, databases, networks, procedures, and people. They are used to perform various intended system tasks.
  • Data are elementary descriptions of things, events, and activities.
  • Information is data organized for meaning and value to the recipient.
  • Knowledge is processed data and information conveying understanding and expertise for solving problems.
  • A business process is a continuous set of related activities producing products or services. Includes inputs, resources, and outputs.

Information System

  • An information system is a collection of related components that use computer technology to perform certain or all of its intended tasks.
  • The components include data, people, processes, information technology (IT) resources or equipment.
  • The study of information systems covers how organizations can use IT as tools to solve business problems and achieve competitive advantages.
  • It needs to address that not every problem is solved by technology and that business skills are crucial.
  • The role of information systems in an organization's structure is significant because of how it helps in knowledge sharing, organizational process redesign, and improvements with organizational culture.

Additional Information

  • The systems development life cycle (SDLC) involves several phases: planning, analysis, design, implementation, and maintenance.
  • Software development is a complex project, often exceeding budget and schedule estimations.
  • Project management skills are crucial to develop good software.
  • A priority matrix is a helpful technique for categorizing project constraints, enhancements, and acceptability.
  • Work breakdown structures (WBS) help assure that project managers identify all products and work elements and assure proper integration and control.
  • A work package is the lowest level of a Work Breakdown Structure (WBS) and identifies details of the work needed.
  • A responsibility matrix assigns tasks and responsibilities for each phase.
  • Process breakdown structures (PBS) focus on the steps for information systems.
  • Project communication plans specify who will get what information and when, how, and by what method. They're crucial for a successful project.
  • Forward pass calculations determine the earliest start and finish times for project activities.
  • Backward pass calculations determine the latest start and finish times for project activities. Identifying potential slack gives insights into time delays
  • A Gantt chart is a project scheduling tool that visualizes tasks, their dependencies, and the time allocated for completion.
  • Resources (people, equipment, and materials) are integral and must be accounted for in project plans
  • Understanding resource constraints such as time limits and resource availability is crucial when planning and controlling project schedules.
  • Data warehouses and data marts use historical data to support decision making. Information systems can make data more accessible that may otherwise be difficult to use.
  • Specific challenges of managing data include data storage issues and integrity issues (e.g., data security, quality, and integrity). Managing different formats and types of data is also a major concern.
  • Data governance approach to manage organizational data and master data management methods.
  • Queries in a database system are used to ask for information. Structured Query Language (SQL) is a common database query language
  • Various types of web servers are used to deliver and retrieve web pages
