ICT - 1 Laboratory - 3 Created by ROGELIO ICDANG BATONGMALAKI JR BSE - 3 Application Software 4 Categories of Application Software is a program or group of programs designed for end users. Example: ER Diagrams (Entity Relationship Diagrams).ģ) Physical design: Defined as a) How users add information to the system and how the system represents information back to the user. You can group software maintenance into four overarching categories: Preventive maintenance. Some of these are JumpStart, MindPlay, Moodle, and Kid Pix. Various kinds of tutorial software are included in this category. Systems Modelling Language (SysML): Used for systems engineering.ġ) Architectural design: To describes the views, models, behaviour, and structure of the system.Ģ) Logical design: To represent the data flow, inputs and outputs of the system. This application software, also termed as academic software, is specifically designed to facilitate learning of a particular subject.

Business Process Modelling Notation (BPMN): Used for Process Modelling language.ĭ. Flowchart : A schematic or stepwise representation of an algorithm.Ĭ. Unified Modelling Language (UML): To describe software both structurally and behaviourally with graphical notation.ī. Some of the examples of graphical modelling languages areĪ. The designs can be defined in graphical or textual modelling languages. A designer uses the modelling languages to express the information and knowledge in a structure of system that is defined by a consistent set of rules and definitions.
