Four level pyramid model
A four level pyramid model of different types of Information Systems based on the different levels of hierarchy in an organization.
The first level represents transaction processing systems for workers.
The second level represents management information systems for middle managers.
The third level represents decision support systems for senior menegers.
The fourth level represents executive information systems for executives.
This triangle chart example is included in the Pyramid Diagrams solution from Marketing area of ConceptDraw Solution Park.

The ER diagram is constructed from the specific ERD graphic elements. There are used 2 types of ERD notations: Chen and Crow's Foot.
A complete set of work flow shapes, notation & symbols for ERD, entity relationship stencils, included in Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software, makes drawing diagrams based on ERD notation as smooth as possible.

There are many ways to track the system in a critical situation. To model a system behavior, uml notation is widely used. Usually, an UML diagram consists of elements such as actor and a case.
This diagram represents the structure of UML notations. Unified Modeling Language (UML) is used in software engineering to depict graphically the software modeling process. UM Language uses graphic notations for developing models of object-oriented systems. These notations displays requirements, sub-systems, logical and physical elements, etc. We created this diagram using ConceptDraw DIAGRAM reinforced with Rapid UML solution. It can be helpful for students on software engineering, when learning UML.

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways.
The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.

UML state machine's goal is to overcome the main limitations of traditional finite-state machines while retaining their main benefits.
ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML State Machine library.

Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering applications.
ConceptDraw DIAGRAM diagramming and vector drawing software was extended with SysML Solution from the Software Development Area of ConceptDraw Solution Park specially to help systems engineers design various model systems with SysML.
A model of a system is defined as a set of hierarchical diagrams representing the asynchronous process of data transformation from the moment it is input to the system to the moment it is output to the user. To demonstrate how a process transforms the initial data, you should design a data flow diagram using a DFD Library included in ConceptDraw DIAGRAM Solution Park. Start your diagramming experience now!
You can use this library of symbols related to data flow diagrams (DFD) to design data-oriented or process-oriented models along with data process diagrams. This vector objects library It is a part of ConceptDraw solution designed for data flow diagramming, along with corresponding samples and templates. A data flow diagram is a 2D flowchart that depicts the sequence of particular activities and operations operations and activities which is accompanied by the dynamic flow of some data.

ConceptDraw DIAGRAM is a Mac OS X and Windows software. Numerous vector stencils, samples and templates created by designers are included in the basic package. This is classic flowchart maker which exactly follows the industry standards using flowchart symbols geathered during a ten years into solution park.
