Database Applications and Privacy Implications

You are just a number to a computer.

A database is like an address book.

Databases

Make it easier to store large quantities of information

Make it easier to retrieve information quickly and flexibly

Databases

Make it easy to organize and reorganize information

Make it easy to print and distribution information in a variety of ways

Database Anatomy

Database program: a software tool for organizing the storage and retrieval of information

Database: a collection of information stored in an organized form in a computer

Table: a collection of related information

Database Anatomy

Record: the information relating to one person, product, or event

Field: each discrete piece of information in a record

FieldRecord

Table

Database Anatomy

The type of information a field can hold is determined by its data type: Alphanumeric strings Integers Floating-point decimals Currency Date/time Logical (true/false) Limited data types (such as state or country)

Using Databases

Browsing Querying Sorting Reporting Mail Merge

Relational Databases

A relational database allows tables to be related to each other.

Changes in one table are automatically reflected in other tables.

Relational databases are organized by key fields which unlock relevant information when it is needed elsewhere.

Batch vs. Real-Time Processing

Batch processing: transactions accumulate throughout the day and are input into the computer in large batches

Real-time processing: allows instant access to information and instant updates

Client/Server Software

Two-way communications occur between applications running on the client PC and the server PC.

Users can take advantage of the client PC’s convenience while still having access to data stored on large server systems.

Client/Server Software

Data Mining

The discovery and extraction of hidden predictive information from large databases

Locates trends and patterns in data that would have been overlooked by normal database queries

Computers and Privacy

Computers control access to personal and identifying information.

More than 15,000 specialized marketing databases contain 2,000,000,000 names and contain personal characteristics like age, income, and religion.

Computers and Privacy

Cookies Identity theft / “phishing” schemes Workplace monitoring technology Surveillance satellites (Google Earth) Global positioning systems in cell phones Surveillance cameras
