Answer (1 of 2): Advantages for a Logical Data Model Easy to understandLogical data models are easy to understand by most users; this basically means that most people can identify what information goes where within the database; this is because all the attributes, entities and relationships are listed clearly, that is why it is easier … pixel to represent locations on the earth. Advantages and Disadvantages of E-R Data Model. process. There are several advantages and disadvantages for using either the vector or raster data model to store spatial data. Comparison between raster data structure and vector data structure. It handles more relationship types, such as M:N and multiparent. Disadvantages. Disadvantage: A small change in the data can cause a large change in the structure of the decision tree causing instability. Raster and vector data both are the spatial data type. There is no data definition or data manipulation language in the DBMS. Following are advantages of an E-R Model: • Straightforward relation representation: Having designed an E-R diagram for a database application, the relational representation of the database model becomes relatively straightforward. There are two types of object based data Models – Entity Relationship Model and Object oriented data … 6. ), as a result – low reliability and effectiveness of budgets. 2. Structure of Mathematical Models 3. An object can store all the relationships it has with other objects, including many-to-many relationships, and objects can be formed into complex objects that the traditional data models cannot cope with easily.
