Many people wonder whether they should start filling the logframe from the top (starting with the goal), or from the bottom (starting with the activities). An entity relationship diagram (also referred to as ER diagram or ERD) is a type of diagram that is intended for graphical presentation of data within a database via various entities, their attributes, and relations between them. Creating a visual representation of a "net list" is often referred to as "graph layout". The main purpose network diagrams serve is to give insights about how the different components in a network work together. Conceptual ERD is the simplest model among all.Note: Conceptual ERD supports the use of generalization in modeling the ‘a kind of’ relationship between two entities, for instance, Triangle, is a kind of Shape. Other organisations may go back and forth between the goal and the activities trying to balance costs against results. Other benefits include the ability to use the model to create the ultimate database as well as consult it later as work with the application progresses. Create/Maintain. What is an ERD? In this section, we are going to draw a simple logical ERD that contains just two entities.

It is supposed to show the logic of how the activities will lead to the outputs, which in tern lead to the outcomes, and ultimately the goal. So while any data flow diagram maps out the flow of information for a process or system, the logical diagram provides the “what” and the physical provides the “how.” For example, if the goal is a “10% increase in the number of Grades 5-6 primary students continuing on to high school within 3 years” then the indicator is “percentage of Grades 5-6 primary students continuing on to high school.”. So just fill the table in whichever order makes the most sense to you. If you crate diagram for the first time you may get the following message: SSMS requires some system procedures and a table that are not created with the database.
