One way to think about it is that a software system is something a single software development team is building, owns, has responsibility for, and can see the internal implementation details of. Unfortunately the term "software system" is the hardest of the C4 model abstractions to define,Īnd this isn't helped by the fact that each organisation will also have their own terminology for describing the same thing, typically using terms such as "application", "product", "service", etc. This includes the software system you are modelling, and the other software systems upon which your software system depends (or vice versa). actors, roles, personas, etc).Ī software system is the highest level of abstraction and describes something that delivers value to its users, whether they are human or not. Which in turn are implemented by one or more code elements (classes, interfaces, objects, functions, etc).Īnd people may use the software systems that we build.Ī person represents one of the human users of your software system (e.g. The presenter can download other Sequence Diagrams or Gantt Charts from the Gallery.In order to create these maps of your code, we first need a common set of abstractions to create a ubiquitous language that we can use to describe the static structure of a software system.Ī software system is made up of one or more containers (applications and data stores),Įach of which contains one or more components, Any modification, even to size, will not affect its graphic resolution so the design remains visually appealing. Text can be inserted and colors can be modified, depending on the user’s preferences. The diagrams permit the user to analyze schedules and implement contingency plans. The Sequence Diagrams for PowerPoint can be employed in project planning for small or large companies. ![]() The timelines are colored in either red or green, depending on whether they represent the actual or estimated times. The timelines are located below the headers, with one timeline placed below another. It is created with five rectangular headers, with text placeholders, found near the top of the slide. This is ideal when the action itself, is more significant than whether it took a long time to apply. This type emphasizes the lengths of each sequence, giving more importance to their implementation. The second type substitutes the line arrows with banner arrows. With these slides, the presenter can bring more focus to the events themselves, rather than the length of time. The first variant uses thin line arrows, in ray form. The PowerPoint template has two principal variations of the sequence diagram. These two types allow the users to compare the times and forecast the lengths of the succeeding events. The first is an estimated timeline, while the second is an actual timeline. There are usually two types of timelines in the diagram. In sequence diagrams, however, several timelines – one for each activity – are shown simultaneously across the same period. ![]() Sequence diagrams use horizontal bars and segments in the same way as a timeline. Sequence diagrams are a kind of interaction diagrams, also known as Gantt charts. ![]() The presentation design contains a sequence diagram for software development and project planning. Organize business plans with the Sequence Diagrams for PowerPoint.
