2. Systems development life cycle - Wikipedia

   en.wikipedia.org/wiki/Systems_development_life_cycle

   A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

3. Software development process - Wikipedia

   en.wikipedia.org/wiki/Software_development_process

   In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .

4. Event-driven process chain - Wikipedia

   en.wikipedia.org/wiki/Event-driven_Process_Chain

   Example of a more complex EPC diagram (in German). An event-driven process chain (EPC) is a type of flow chart for business process modeling. EPC can be used to configure enterprise resource planning execution, and for business process improvement. It can be used to control an autonomous workflow instance in work sharing.

5. High-level design - Wikipedia

   en.wikipedia.org/wiki/High-level_design

   High-level design (HLD) explains the architecture that would be used to develop a system.The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.

6. Activity diagram - Wikipedia

   en.wikipedia.org/wiki/Activity_diagram

   Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.

7. Data model - Wikipedia

   en.wikipedia.org/wiki/Data_model

   Data-Flow Diagram example [19] A data-flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data-flow diagram can also be used for the visualization of data processing (structured design).

8. System context diagram - Wikipedia

   en.wikipedia.org/wiki/System_context_diagram

   Decision trees and data storage are represented in system flow diagrams. A context diagram can also list the classifications of the external entities as one of a set of simple categories [5] (Examples: [6]), which add clarity to the level of involvement of the entity with regards to the system. These categories include:

9. V-model (software development) - Wikipedia

   en.wikipedia.org/wiki/V-Model_(software_development)

   The V-Model reflects a project management view of software development and fits the needs of project managers, accountants and lawyers rather than software developers or users. Although it is easily understood by novices, that early understanding is useful only if the novice goes on to acquire a deeper understanding of the development process ...
