Use Cases and CRUD ~ Learn Information System

Introduction Use Case Diagram Technique

A use case represents an activity performed by the system, which is usually a response based on the request of a user. Two (2) The recommended technique for identifying use cases is the goal user technique and also event decomposition technique. Additional techniques can also be used CRUD technique, which is often used to validate the use cases and enrich the existing list.

Use Cases and CRUD

Another important technique that can be used to validate and evaluate use cases are CRUD technique. "CRUD" is an acronym for Create, Read or Report, Update, and Delete, which is usually associated with database management. Analyst will begin by looking at the type of data to be stored in the system, which is typically modeled with data entities or domain classes. To validate and evaluate use cases, analysts will look at each type of data and verify that the use cases shall consist of create the data read or report on the Data, update the data, and delete (or archive) the data.

Steps to validate and evaluate the CRUD use cases using the technique is as follows:
1. Identify all data entities or domain classes involved in the development of new systems.
2. For each type of data (data entities or domain class), verify that a use case has been identified can do creates, updates, reads (or reports), and deletes (or archives) data.
3. If there is the addition of a new use case, identify who the stakeholders involved and their evaluation.
4. Ensure that clear about who is responsible for the conduct of the use cases.
