Entity Relationship Diagram Software Engineering
Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases. Introduced by Peter Chen the ER modeling technique is now successfully used in software development, when creating conceptual data model of an information system.
There are used three basic elements for ERDs construction: entities, attributes, relationships. Chen's notation for ERD assumes the use of rectangles to represent entities and diamonds to represent relationships between first-class objects. Another popular notation for ER diagrams is Crow's foot notation.
Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.

Any factory needs a clear scheme of all the equipment used in the manufacture processes. So, if you want to place all your machines and equipment on one diagram, you need a good diagramming tool for that. For instance, you can find all the design elements you might need, such as lathes, milling machines or saws on ConceptDraw DIAGRAM Solution Park in Plant Layout Plans solution in appropriate libraries.
This drawing represents the Machines and Equipment library delivered by ConceptDraw Plant Layout Plans solution. This vector library is supplied along with other libraries related to industrial architecture planning and interior design.
Just planning the proper facilities in a proper right place, allows to manufacture a product in the most effective and economic way. Objects containing in these libraries will be helpful for architects and engineers dealing with industrial buildings design. They are intended to use for designing layouts of plants, warehouses, manufacturing workshop etc.

UML Class Diagrams is a type of static structure diagram that is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code. It describes the structure of a system by showing the: classes of a system, attributes, operations, and the relationships between them.
The Rapid UML Solution for ConceptDraw DIAGRAM includes the UML Class Diagram library that helps you to design the UML Class Diagram quick and easy. You can simply and quickly drop the ready-to-use objects from the library into your document to create the UML Class Diagram.

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.

Big and complex projects sometimes need some simplification of plans and schedules. That's why Program Evaluation and Review Technique was invented and first implemented in 1958. You can create PERT diagrams effortlessly with ConceptDraw DIAGRAM and share them with your colleagues.
Program Evaluation Review Technique (PERT) is a method that is used to assess and analyze projects. PERT is a valuable tool for the project management practice. PERT gives an assessment and analysis of the time needed to the project completion. A PERT chart is a visual tool that delivers a graphical view of a project timeline. It is used to display the sequences and dependences of project tasks necessary to complete a project. ConceptDraw DIAGRAM delivers the possibility to build a PERT along with other diagrams applied to assist management process by using its Seven Management and Planning Tools solution.
