Components of ER Diagram

Entity-Relationship model gives the possibility to visually describe a database using the components of ER Diagram, entity relationship stencils, relationship symbols, work flow shapes. ER-diagram lets represent the data or entities, attributes of these entities and relationships between them, using standardized Crow’s Foot notation icons or Chen’s notation icons. An entity is an object of the real world, it can exist independently and has the instances which differ in attribute values (properties). The attributes give an unambiguous (uniquely) identification for the instance and are called the primary key, this key can be composite and combine several attributes. ConceptDraw DIAGRAM is a professional software available with Entity-Relationship Diagram (ERD) solution from Software Development area that lets create ERDs for various database systems, using Crow’s Foot and Chen’s notations. It is invaluable tool for software engineers and developers, it supports ODBC-compatible databases (Oracle, MySQL, MS Access, MS SQL, InterBase, Firebird and others).

Example of DFD for Online Store (Data Flow Diagram)

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw DIAGRAM enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols.

Software and Database Design with ConceptDraw DIAGRAM

Unified Modeling Language (abbr. UML) is a modeling language used by software developers and software engineers for developing diagrams, expressive modeling, visualization, construction, specification, and documentation an information about software-intensive systems. There are used many types of UML diagrams, joined in main groups, each of them has its own functional abilities and applications: Behaviour diagrams illustrate the functionality of software systems, Structuring diagrams depict a structure of objects at the systems, Interaction diagrams show the flow of control and data among the things in a modeling system. UML has a lot of practical applications in varied areas, among them software development, hardware design, banking and financial services, telecommunication, science, research, enterprise information system, distributed Web-based services, user interfaces for web applications, medical electronics, patient healthcare systems, etc. ConceptDraw DIAGRAM extended with Rapid UML solution is a perfect tool for UML diagramming.
