 Relational Database Fundamentals

4.  Database maintains information about various types of objects
(inventory), events (transactions), people (employees), and
places (warehouses)
 Hierarchical base model information organized into a tree-like
structure that allows repeating information using parent/child
relationship
 Network database model is a flexible way of representing
objects and their relationships.
 Relational database model is a type of database that stores
information in the form of logically related two-dimensional
tables.
 Entities and Attributes

 Process of analyzing data to extract information not
offered by the raw data alone

 Data-mining tools
 Use a variety of techniques to find patterned and
relationships in large volumes of information
 Infer rules from them that predict future behavior and
guide decision making
