Database Concepts - Logical vs Physical DATA MODEL LOGICAL DATA MODEL: Represents business information and defines business rules PHYSICAL DATA MODEL: Reflects the physical implementation of the model in the database Note: There is not necessarily a one-to-one relationship between entities/tables and attributes/columns. Entity Group (set) of related Table data elements Attribute Individual data Column element
Database Concepts - Columns & Rows Columns Rows Row = Single line of related data elements with a unique key. (Key may be comprised of multiple columns). Standard typed format for a data attribute = AREA.FILE_KEY
Normalized Database: Each table contains related attributes for one entity. Attributes are not duplicated in any other table. Database Concepts - Normalized Database

Sequence: Sequential numeric values that uniquely identify a row of data within a table, and are often used as primary keys. Oracle provides a mechanism to keep tract of and assign these sequences. Referential Integrity: Requires that the relationships between the data be maintained so that inaccurate and unbalanced conditions do not occur. For instance, codes must be valid on supporting tables and when data is deleted, no orphaned data remains. Database Concepts - Sequences & Referential Integrity

Code Tables: Allows users to define multiple values for specific attributes that may be validated. In TLS, code tables typically contain a 3 character, alphanumeric code and a textual description. Descriptions are displayed in the applications as a result of joins to the code tables. Rule Tables: Used to limit the selection of codes within TLS by application, group code or other variable. Rule tables are set up to enforce application business rules. Relation Tables: Support a many-to-many relationship between tables. Relation tables typically carry just the sequential keys for the two tables being related. Database Concepts - Code, Rule, Relation Tables

“Flat” Files (RPT*_Tables): Denormalized tables populated via triggers used for reporting to enhance performance. Database Concepts - “Flat” Files

Table Joins: Tables are joined together by linking their primary keys, or other values. Joins establish the path from one table to another, or the link between the tables. The path for table joins may also create a hierarchy of joins. Some unique categories of joins that occur in the TLS model are: Joining tables via primary keys Joining tables via relation tables Joining tables to code tables Joining tables to remarks tables (one example of a hierarchy) Database Concepts - Table Joins

Triggers: Internal programs the system uses to populate denormalized tables. Triggers fire upon insert, update or delete. Stored Procedures: Programs that run in Oracle to perform tasks. Views: Read only versions of the database that support queries and reports regarding a broad category of data by joining multiple tables into a single more easily used table.
