Developing Entity Relationship Diagrams

When you need to visually represent the structure of relational database, Entity relationship diagram (ERD) is a type of diagram for that case. Most entity-relationship diagrams can be built with objects from Flowchart solution or ERD Solution which contains inbuilt templates. Follow these steps to create your own custom ERD diagram. Don't be frightened if it looks complex, ConceptDraw DIAGRAM makes it easy to create an ERD, and hundreds of other diagrams, in minutes.

Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams

ER-model is a data model which lets describe the conceptual schemes in a specific subject area. It can help to highlight the key entities and specify relationships that can be established between these entities. During the database design, it is realized the transformation of ER model into certain database scheme based on the chosen data model (relational, object, network, etc.). There are used two notations for ERDs: Crow's Foot and Chen's. Crow's Foot notation proposed by Gordon Everest represents the entity by rectangle containing its name (name must be unique within this model), and relation - by the line which links two entities involved in relationship. The relationship's plurality is graphically indicated by a "plug" on the end of the link, the optionality - by a circle. Entity-Relationship Diagrams based on Crow's Foot notation can be easily drawn using the ConceptDraw DIAGRAM. Extended with Entity-Relationship Diagram (ERD) solution, it is the best ERD diagrams software with powerful tools and ready design elements for Crow's Foot and Chen notations.

Data structure diagram with ConceptDraw DIAGRAM

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw DIAGRAM.

Databases Access Objects Model with ConceptDraw DIAGRAM

ConceptDraw Basic gives the opportunity of interaction with any ODBC-compatible databases. For this the Database Access Objects Model is provided. All calls to the database are made by certain methods of objects of this model.

Martin ERD Diagram

The vector stencils library Crow's Foot Notation from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Crow's foot notation such as relationship symbols and entity symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.

Swim Lane Diagrams

Swim Lane Diagrams are the kind of process flow diagrams and effective tool for documenting the business processes required for any business company for its productive work, for easy defining the weak points, reasons of defects, or delays during the process. Swim Lane Diagram is based on the IDEF3 standard and was developed primarily for using in projecting. Its name derives from the use of horizontal or vertical lanes. The blocks that denote the parts of the processes are arranged within definite lanes according to the belonging to responsible worker. So the process of any complexity is visually divided into the parts and represented with indication the responsibility for execution of each part. This significantly facilitates the comprehension of its work. Use the ConceptDraw DIAGRAM software and predesigned vector objects from the Swim Lanes library of Business Process Mapping Solution included to ConceptDraw Solution Park to easy develop Swim Lanes Flowcharts and Diagrams, for modeling and documenting the business processes in a simple and visual graphic form.
