This house of quality sample illustrates interrelationship matrix.
It was designed on the base of the figure 3-4 in Lecture "How QFD helps in product quality improvement?" from the website of National Programme on Technology Enhanced
Learning (NPTEL), India. [nptel.ac.in/ courses/ 110101010/ downloads/ mod3/ Module%20 III-Lec1.pdf]

"The next step in building a house of quality is to compare the VOC with technical characteristics and determine their interrelationships. In this context, engineering knowledge about the product and historic evidence/ data can provide useful information. Common practice is to use symbols to represent the nature of relationship between customer requirements and technical descriptors. Symbols used are:
- A solid circle represents a strong relationship (scored as +9).
- A single circle represents a medium relationship. (scored as +3).
- A triangle represents a weak relationship (scored as +1).
- The box is left blank if there is no relationship between VOC and technical characteristics.
Figure 3-4 provides the interrelationship matrix with type of relationships. Any cell that is empty implies no or insignificant relationship." [nptel.ac.in/ courses/ 110101010/ modules/ module3/ lec1/ 1.6.html]
The HOQ example "House of Quality - interrelationship matrix" was designed using ConceptDraw PRO software extended with House of Quality solution from Quality area of ConceptDraw PRO Solution Park.

Entity Relationship Software

Entity Relationship Diagram (ERD) is a leading data modeling tool that is used to illustrate the logical structure of database, helps to organize and represent your project's data in terms of entities, attributes and relationships. To describe the database structure usually is used the ERD Chen's or Crow's Foot notation. Chen's notation supposes the representation of entities by rectangles with the entities names inside, relationships by diamonds and attributes by ovals connected with a line to exactly one entity. In Crow's Foot notation the boxes are used to depict the entities and their attributes, the lines between them - to depict relationships. ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) Solution is convenient and useful for designing the ER Diagrams, and supports the use of Chen's or Crow’s Foot notation according to your needs and desires. The ERD diagrams produced with ConceptDraw DIAGRAM Entity Relationship Diagram software can be successfully used in whitepapers, presentations, posters, datasheets, technical materials, etc.

Entity Relationship Diagram Examples

Entity Relationship Diagram Examples
Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution.

Entity-Relationship Diagram (ERD) with ConceptDraw DIAGRAM

Entity-Relationship Diagram (ERD) is applied for detailed description of structures and high-level (conceptual) design databases using the Chen's and Crow's Foot notations. An ERD represents a diagram constructed mainly of rectangular blocks (for entities, data) linked with relationships. The links between the blocks are used to describe relations between the entities. There are three types of relationships: one-to-one, one-to-many, and many-to-many. Use the specialized ERD software - ConceptDraw DIAGRAM to create the Entity-Relationship Diagrams (ERDs) of any degree of complexity with Chen's and Crow's Foot notations. Draw them easily applying the powerful built-in tools and libraries of predesigned ERD vector objects from Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park. You can also start with one of ready template or sample included to this solution. Designing the ERDs in ConceptDraw DIAGRAM you can easy move the objects within a diagram with saving the relationships between them.
