General objective of this case study is to analysis Data Modeling by Surveying Project. Data modeling in software engineering would be the process of making a data model with an information system by applying formal data modeling methods. Other objectives of this case study are: Understand and perform the techniques for entity discovery and Define each entity with respect to the business and complete an entity matrix. here also focus on to perform the necessary data modeling techniques to organize and document the data requirements for the proposed system. Finally construct the Context, Key-Based, and fully attributed data models.
