The Evolution of Data Models The quest for better data management has led to different models that attempt to resolve the file system’s critical shortcomings. Because each data model evolved from its predecessors‚ it is essential to examine the major data models in roughly chronological order. 1.1 The Hierarchical Model A Hierarchical Database Model is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships:

The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented‚ how the information-exchange requirements are implemented‚ and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly‚ as shown in Figure 31. For some purposes‚ an additional entity-relationship style diagram

In this background lesson‚ you are going to use a data modeling technique—specifically‚ EntityRelationship Diagrams (ERDs)—to model the business scenario from Lesson 2. The data model you create in this lesson will form the foundation of the database that you use throughout the remaining lessons. Before you sit down in front of the keyboard and start creating a database

The discussions of the different types of mistakes that are made in the design phase that led to a poor database design are also discussed. Mistakes include the lack of careful planning‚ proper normalization of data‚ poor naming conventions‚ lack of sufficient documentation and extensive testing. The ERD for the database will be revealed along with the choice of the program to manage the database and allow for versatility for various platforms‚ applications‚ and features. Huffman Trucking’s
