Entity Relationship (ER) diagrams are drawn when designing a database system, After the systems specification, an ER diagram is drawn showing the conceptual design of the database, this diagram shows the type of information that is to be stored in the system and how these information associate with each other (e.g. one-to-one, one-to-many, etc).ER Diagrams are simple and easy to understand, thus, this diagram can be shown and explained to user representatives for confirmation and approval.use of er diagram

There are several different places in which an Er-Diagram can be found. Photobucket has pictures of Er-Diagrams that can be examples for a College Management System Project.

In software engineering, an Entity - Relationship model(ER model for short) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams or ER diagrams.learn more www.ngprakasam.hpage.com

It is the Rough Endoplasmic Reticulum that has ribosomes attached to it, hence the name "rough". The smooth endoplasmic reticulum does not contain any ribosomes.No.The smooth endoplasmic reticulum (ER) does not have any ribosomes attached to it. That is one of the major differences between the smooth ER and the rough ER which does have attached ribosomes.
