Lecture 1: Forward Engineering: ERD to Relational Model: (Remember these rules, Chapter 6 of LIU)
Each entity set is converted into a table with its attributes as the columns of the table
Depending on the mapping cardinality, you modify the tables to make them related
If the relationship is 1:m or m:1, you put the primary key of the table for one-side entity set into the table for the many-side entity set
If the relationship is m:m, you build a junction table which has the primary keys of both entity sets as columns
If the relationship is 1:1, you can put the primary key of one entity set into the table for another entity set... more >>

(641 Week 1 Outline) Concept of Database:
Database is a set of records well organized using a particular logical data model
Records: A records is an array of observed characteristics (or attributes) on one object (entity)
Well Organized: 1) related records are connected; 2) no unnecessary redundancy
Logical Data Models: Hierarchical, Network, Relational
Database Development Process
Data Modeling: Entity, Attribute, relationships
Database Implementation: DBMS
CASE Tool: Oracle Data Modeler
Terminology Confusion: logical model = conceptual model, relational model = logical model
How to draw entities, create attributes, and refine relationships using Oracle Data Modeler
Data Modeling: Identify Objects, Attributes, and Relationships
Identify Objects: (1) objects can be tangible such as a customer or intangible such as an account or meeting; (2) objects must be observable at an instant in time; (3) objects must have multiple attributes (or dimensions) to be observed... more >>
