Steps In Building the Data Model
{"Image DocumentName": "Steps In Building the Data Model", "Image ImageDescription": "While ER model lists and defines the constructs required to build a data model, there is no standard process for doing so. Typically, the entities and relationships are modeled first, followed by key attributes, and then the model is finished by adding non-key attributes. The sequence used for this course are: Identification of data objects and relationships. Drafting the initial ER diagram with entities and relationships. Refining the ER diagram. Add key attributes to the diagram. Adding non-key attributes. Validating the model through normalization. Adding integrity rules to the Model.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
