This chapter focuses on the database life-cycle step that is of particular interest when designing relational databases: transformation of the conceptual data model to candidate tables and their definition in SQL. There is a natural evolution from the entity-relationship (ER) and unified modeling ...
The three levels of data modeling, conceptual data model, logical data model, and physical data model, were discussed in prior sections. Here we compare these three types of data models. The table below compares the different features: Feature...
Conceptual database design is the highest level of abstraction in the database design process. At this stage, designers focus on understanding the problem domain and defining the overall structure of the database without getting into technical implementation details. The primary goal is t...
We propose a general framework for modeling trajectory patterns during the conceptual design of a database. The proposed framework is a result of several works including different data mining case studies and experiments performed by the authors on trajectory data modeling and trajectory data mining. ...
Data Modeling is a process of formulating data in an information system in a particular structure so that it can help in easy reporting in future. It helps in analyzing data that will further help in meeting business requirements.
