Study Notes
Software Engineering Process
- The implementation stage is where an executable software system is developed.
Software Development Approaches
- An example of a possible approach to implementing a medical records system is buying off-the-shelf systems.
Design and Implementation Activities
- Software design and implementation activities are invariably inter-leaved with testing and validation activities.
Design Process
- When developing an application using off-the-shelf systems, the design process becomes concerned with how to integrate and customize the off-the-shelf systems.
COTS Definition
- COTS stands for Commercial Off-The-Shelf systems in the context of software systems.
- COTS refers to pre-existing software systems that can be purchased and tailored to meet specific needs.
Software Design
- Software design is the process of transforming the requirements into a detailed and complete specification of the software system.
Implementation
- Implementation is the stage in the software engineering process where the designed software system is constructed.
Off-The-Shelf Systems
- Buying off-the-shelf systems can be cheaper and faster than developing a system from scratch, as it reduces development time and costs.
