Bibliographic Information
Describes documents
What is a document (revisited)?
Choice of descriptive elements and content of those elements typically governed by a set of rules:
AACR II
Elements coded in standard ways for transmission.
MARC
Goals of Descriptive Cataloging
1. To enable a person to find a document of which
the author, or
the title, or
the subject is known
2. To show what a library has
by a given author
on a given subject (and related subjects)
in a given kind (or form) of literature.
3. To assist in the choice of a document
as to its edition (bibliographically)
as to its character (literary or topical)

Files and Databases
File: A collection of records or documents dealing with one organization, person, area or subject. (Rowley)
Manual (paper) files
Computer files
Database: A collection of similar records with relationships between the records. (Rowley)
bibliographic, statistical, business data, images, etc.
Database
A Database is a collection of stored operational data used by the application systems of some particular enterprise. (C.J. Date)
Paper "Databases"
Still contain a large portion of the world’s knowledge
File-Based Data Processing Systems
Early batch processing of (primarily) business data
Database Management Systems (DBMS)
Database Data Models
Hierarchical Model
Similar to data structures in programming languages.
Database Data Models
Network Model
Provides for single entries of data and navigational "links" through chains of data.
Database Data Models
Relational Model
Provides a conceptually simple model for data as relations (typically considered "tables") with all data visible.
Database Data Models
Object Oriented Data Model
Encapsulates data and operations as "Objects"
Database Design Process
Database Design Process
Conceptual Requirements
Systems Analysis Process
Examine all of the information sources used in existing applications
Identify the characteristics of each data element
numeric
text
date/time
etc.
Examine the tasks carried out using the information
Examine results or reports created using the information
Database Design Process
Conceptual Model
Merge the collective needs of all applications
Determine what Entities are being used

What are the Attributes of those entities?
Properties or characteristics of the entity
What attributes uniquely identify the entity
What are the Relationships between entities
- How the entities interact with each other?
Database Design Process

How is each entity and relationship represented in the Data Model of the DBMS
Hierarchic?
Network?
Relational?
Object-Oriented?
