Software Engineering Diagrams

In software engineering, you can use various diagramming notations to describe and understand the designed solution from different perspectives. The diagrams can be used as a design tool and later as a part of the documentation.

Software engineering is a set of engineering methods used in the software development of system applications. It defines principles for specification, design, development, testing, evaluation, and maintenance.

Diagrams for Software Development

Software Ideas Modeler allows you to utilize its toolset to bring engineering methods to your software development. You can use various diagram notations to describe the designed software. The UML notation is the most universal notation you can use to define various aspects of the modeled solution. Usually, you should start with the UML use case diagram that allows you to define the purpose of the system and identify the roles (actors) within it. You can describe the processes using UML activity diagrams. Then you can continue with UML component diagrams to identify the modules and components in the system and the dependencies between them. UML class diagram allows you to dig deeper and specify the individual entities. UML state machine diagrams provide additional details to the defined classes or other entities – they allow you to analyze various states of the objects and transitions between them as a reaction to supported actions. With UML sequence diagrams, you can trace the flow of messages between objects or types of objects. If you want to show which servers or devices are used for running the system, you can depict it using a UML deployment diagram.

A typical software system uses database systems for its data layer. You can use class diagrams to design the data model, or preferably entity-relationship diagrams (ERD).

Diagram for Software Architecture

The best diagram for high-level software architecture is Layer Diagram. It offers blocks for tiers, modules, and components. It allows you to define relationships and responsibilities. Also, UML diagrams such as a Component diagram and Deployment diagram can be convenient for this purpose.

Diagrams for Software Design

User interface blueprints and sketches are one of the crucial parts in software design. The time you devote to design is not a waste. It will come back to you in the form of an improved user experience.

If you want to design screens and pages in your application, the wireframing diagrams can be handy. You can use User Interface Diagram for desktop applications, Web Page Diagram for websites and web applications, Mobile App Diagram for your smartphone app designs. You can also model the flow between the various application views using Screen Flow Diagram.

What Is the Difference Between Simple Diagrams and Software Engineering Diagrams?

You can draw simple diagrams with any drawing editor. Diagrams in Software engineering include more meta-data. They define an internal model, that allows you to hyperlink and reuse the model elements. Software Ideas Modeler provides for all the elements the documentation definition and a set of custom tagged values. You can track various versions of your models. The advanced tools help you to define mappings between different parts of your models. Then the diagrams can offer views on various aspects of the solution and its model.
