The Entity Relationship Diagram (ERD) depicts a conceptual data model that incorporates some of the important scientific information about the real world. It adopts a natural view that the real world consists of entities and relations (Chen‚ 1976). One objective of the ERD is to create a simple‚ easy to understand and conveniently presented data model consisting of entities‚ attributes‚ relationships and cardinalities. The model serves as tool for database design‚ where the model can facilitate communication

An Examination of the History‚ Development‚ and Uses of the Beck Depression Inventory Maya A. Butler Richmont Graduate University Dr. Aaron Beck is a psychiatrist widely known for developing the Beck Depression Inventory (BDI); a self-assessment instrument used to assess the severity of depression in adolescents and adults.

Component Diagram Notations The component diagram’s main purpose is to show the structural relationships between the components of a system. In addition‚ component diagrams are useful communication tools for various groups. In creating a component diagram‚ there are different notations that can be used to show the different relationship of each component within the system. The component diagram notation set now makes it one of the easiest UML diagrams to draw: * COMPONENT A component can

E-R Diagram Introduction:- In 1976 ‚Chen developed the Entity-Relationship Diagrams ‚a high-level data model that is useful in developing a conceptual design for database . An ER diagram is a diagram containing entities or “items”‚ relationships among them‚ and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community‚ it is considered a natural and easy-to-understand way of conceptualizing the structure of database.

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Week 1-Discussion 1-Circular Flow Diagram To first explain how the circular flow diagram relates to the current economic situation‚ one must realize that the two‚ three‚ and four sector models no longer apply to the United States any more. Only the five sector model currently applies. The five sector model of the circular flow of income is a more realistic representation of the economy and has a more definitive look as to what and how economics really is in the world. In the more simplistic two

Definition of the Inventory Theory Inventory theory (or more formally the mathematical theory of inventory and production) is the sub-specialty within operations research that is concerned with the design of production/inventory systems to minimize costs. It studies the decisions faced by firms and the military in connection with manufacturing‚ warehousing‚ supply chains‚ spare part allocation and so on; it provides the mathematical foundation for logistics. Inventories are materials stored
