entities are objects outside the system‚ with which the system communicates. External entities are sources and destinations of the system’s inputs and outputs. 1.b) ENTITY RELATIONSHIP DIAGRAM Entity–relationship model (ER model) in software engineering is an abstract way to describe a database. This article refers to the techniques proposed in Peter Chen’s 1976 paper.An ER model is an abstract way to describe a database. There are three basic elements in ER models: Entities are the "things"

Q1: what was the reason for the loss of the contract? 1- (DOE) failed to award the contract to Kombs Engineering for the simple reason they lacked faith in Komb’s project management systems because the failure to provide such a project management system by Kombs . 2- Kombs during the time it was contracted with the DOE for a period of five years and it never took time to develop a proper system of managing projects and they never released that the dynamics and tools involved in project management

well. Typical work activities of an automotive engineer consist of working on the development of land-based vehicles and their activities are either‚ design new products or revising existing ones‚ research and development‚ finding solutions to engineering problems‚ or production of new cars. Most graduates start with a formal training program that lasts about 12-24 months‚ which is a series of placements in different departments in the company. During this time the graduate gains a general knowledge

AmirAshkan Semyary By using the techniques of genetic engineering scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell. It is necessary to obtain a gene to modify genetic material. First a scientist isolates plasmid DNA from bacteria and DNA carrying a gene of interest from cells of another organism‚ such as an animal. A piece of DNA containing the gene is inserted into a plasmid‚ producing recombinant DNA
