Entity Relationship Model

One of the most popular semantic data models is the "entity-relationship" model (often called ER-model). Most of the modern approaches to the database (mainly relational) design are based on the usage of different versions of ER- model. The model was proposed by Peter Chen in 1976. Domain modeling is based on the use of graphic charts, including a small number of heterogeneous components. The simplicity and the presentation clarity of the conceptual basis of these ER-model schemes led to its widespread deployment in the CASE-systems that support automatic design of relational databases.

The basic concepts of ER-models are the entity, the relation and attribute. An entity is a real or abstract object, information about which should be kept and be available. The entity in an ER-model diagram is represented by a rectangle containing the name of the entity. In this case, the name of the entity is not a particular instance of this entity, but a label for the whole entity. Although it would be more correct to use such terms as ‘an entity type’ and ‘an instance of the entity type’ to avoid verbosity, in cases where it does not lead to ambiguity, the term “entity” is used in the meaning of the entity type. For instance, let’s think of an entity named “airport”. In this case, “airport” is the entity type, and “Heathrow” or “Charles de Gaulle” are the instances of this entity.

A relation is a graphically depicted association between two entities. As well as the entity, a relation is a typical concept, all instances of the linked entity types are subject to the rules established by the connecting. Therefore, it is more correct to speak about the relationship type made between types of entities and about the instances of relationship types made between instances of the entity type. In common ER-model this association is always binary and can exist between two different entity types or can be recursive.

How To use House Electrical Plan Software

Electrical plan is a document that is developed during the first stage of the building design. This scheme is composed of conventional images or symbols of components that operate by means of electric energy. To simplify the creation of these schemes you can use house electrical plan software, which will not require a long additional training to understand how to use it. You only need to install the necessary software ant it’s libraries and you’ll have one less problem during the building projection. Any building contains a number of electrical systems, including switches, fixtures, outlets and other lightening equipment . All these should be depicted in a building electrical plans and included to general building documentation. This home electrical plan displays electrical and telecommunication devices placed to a home floor plan. On the plan, each electrical device is referenced with the proper symbol. Electrical symbols are used for universal recognition of the building plan by different persons who will be working on the construction. Not all possible electric symbols used on a certain plan, so the symbols used in the current home plan are included to a legend. The electrical home plan may be added as a separate document to a complete set of building plans.Electrical and Telecom Layout House Plan, electrical symbols

Entity Relationship Diagram Software Engineering

While designing a conceptual data model, you should use appropriate software. For instance, ConceptDraw PRO is a user-friendly ER diagram tool that has a lot of samples and templates to facilitate your work. A clear entity-relationship diagram helps to define the relations between system’s components. Software engineering is the section of a computer science engaged to design, realization, and support of complex software products. An ERD is a data modeling method that is widely applied in the software engineering practice. Commonly it is used for developing a structure of a a relational database. An entity relationship diagram is helpful for structuring and organizing databases that can be modeled using a relational structure. An entity relationship diagram is designed to depicts the interrelationships within the sets of entities which are accumulated in the database. Each entity represents a particular component of a data. Thus, ER diagrams depicts the logical structure of databases. ConceptDraw ER Diagrams solution provides software engineers with the professional tool for making entity-relationship diagrams.Entity Relationship Diagram Software Engineering

How To Create Restaurant Floor Plan in Minutes

As restaurant industry is growing rapidly nowadays, researches show that almost half of the adults have worked in a restaurant or a cafe. Moreover, many of them dream to start their own someday. Unfortunately, it takes a lot of time to write a business plan and to find a great location, although some know how to create a restaurant floor plan in minutes or how to plan budget effortlessly. Hiring employees can also cause a lot of headache, but this is crucial for further success, because every guest comes to restaurant for a good service and delicious food. It is also worth noting that restaurant concept is also important, because it defines target audience and influences the menu. This diagram represents the floor plan of an ongoing sports-theme establishment - restaurant, cafe, or other food service. A number of widescreen monitors installed along the perimeter provide visitors the opportunity to follow the course of a match from anywhere in the dining room of restaurant or cafe. The most of sports fans believe that food and alcohol is a big part of any sports show. That is why the dining room takes the most space - almost 60% of the total establishment space. Nearly all sports fans consume beverages while watching sports - beer, soda or water at least. Thus, the restaurant floor plan designers added a large lavatory there. Moreover, project developers considered unnecessary the gender division of such delicate place - perhaps they guess that only men are watching football, or believe that alcohol will eliminate the most of gender differences.Design  Restaurant Floor Plans
