Study Notes
WAS Functional Modeling Methods
- Web Application Systems (WAS) are complex with a large number of functions.
- System requirement analysis is essential for design, development, and testing.
- WASFM (Web Application System Functional Model) is a formal model for describing WAS functions.
Common Function Modeling Methods
- UML (Unified Modeling Language) is a standard modeling language used in object-oriented technology.
- IDEF0 (Integrated Definition for Function Modeling) is a function modeling method.
- GTST (Goal-tree Success-Tree) is a functional modeling method.
- GTST divides the system into small goals, creating a goal tree and success tree to represent system functions.
- GTST is suitable for simple systems, but for complex systems, the model becomes too large and difficult to understand.
WASFM Model Definitions
- WASFM defines three types of functions:
- Catalog function: Navigational links to arrange system contents.
- Page function: Functional links that correspond to a specific web page.
- Button function: Operative buttons corresponding to specific operations.
- WAS functions are represented as a set of catalog, page, and button functions.
WASFM Components
- FR (Functional Requirements): A set of catalog, page, and button functions
- CF (Catalog Function): A combination of function name, level, and parent function (PAF)
- PF (Page Function): A combination of function name, URL, PAF, and page contents (PC)
- BF (Button Function): A combination of function name, operation name (ON), parent function page (PF), operation logic (OL), and corresponding list area (CL)
- AD (Area Description): An area within a page, with an ID, position, area type (AT), and area content (AC).
- SAC (Static Area Content): A static area within a page, with a content description (CD).
- NAC (Navigation Area Content): A navigation area within a page, with a navigation description (ND) and relationship (NR).
- QAC (Query Area Content): A query area within a page, with query field description (FD), fields relationships (FR), query type (QT), and corresponding list area (CL).
- FD (Field Description): A field within a page, with field name (FN), control type (CT), empty status, value, default, and field limit (FL).
- LAC (List Area Content): A list area within a page, with columns (Col), column sequence (CSeq), rows (Row), row sequence (RSeq), sorting options (Sort), page number (PN), refresh settings (Refresh), and refresh frequency (RF).
- FAC (Form Area Content): A form area within a page, with field descriptions (FD).
- PAC (Page Area Content): A page area within a page, with a content description (CD).
WASFM Model Example
- The example uses DMIMS (University Information Management System) to demonstrate WASFM practical application.
- DMIMS has five top modules: System Management, Course Management, Reservation Management, Content Management, and Achievements Management.
Conclusion
- WASFM provides a formal way to describe web application functions with precision.
- Applying WASFM enables:
- Accurate understanding of system requirements.
- Clear development task definition.
- Detailed system comprehension for testing purposes.
- Potential for automated programming and testing.
