Overview:
Students will learn to structure tables properly, use the principles of data normalization and table relationships, enable data-entry accuracy, use queries effectively, and enhance form and report designs to present data effectively.
Prerequisites:
Paradox 9: Introduction or equivalent knowledge.
Target Student:
Students enrolling in this course should have a basic level of understanding of and experience using the Paradox 9 interface, and has used it to design tables, simple queries, forms, and reports.
What's next:
Paradox 9: Introduction is the first course in this series
Performance-Based Objectives:
Lesson objectives help students
become comfortable with the course, and also provide a means to
evaluate learning. Upon successful completion of this course,
students will be able to:
- Work with keyed tables by structuring them
properly and by creating secondary indexes.
- Organize
tables in a database by following data-normalization
rules.
- Classify
tables by determining the types of relationships they
have, and create relationships between tables by linking
and establishing referential integrity.
- Increase
the accuracy of data entry by specifying validity checks
and creating lookup tables.
- Manipulate
data in tables by using queries to search for special
characters, update multiple records, and link tables.
- Create
custom forms that use memo fields, calculated fields, and
combo boxes.
- Create
custom tabular reports by changing a style sheet,
defining a table frame object, adding enhancements to
improve the report appearance, and using page layout and
print settings.
Delivery Method:
Instructor led, group-paced, classroom-delivery learning model with structured hands-on activities.
Hardware/Software Requirements:
To run this course, you will need:
- A 486 or faster processor
with a minimum of 16 MB of RAM. (We recommend a Pentium

space to install Paradox and the default graphics and
utilities components, including the Borland Database
Engine 5.01 utility.
- Either a local CD-ROM
drive or access to a networked CD-ROM drive for
installation purposes.
- A 3.5" 1.44 MB
floppy-disk drive.
- A VGA or higher resolution
monitor.

IntelliMouse, or compatible pointing device.
- An installed printer
driver. (Printers are not required; however, each PC must
have an installed printer driver to use Print Preview.)
- Microsoft Windows 95,
Windows 98, or Windows NT 4.0.
- A custom installation of
Corel WordPerfect Office 2000 Professional—see the
following section, Class Requirements, for additional
instructions. This course was developed by using Paradox
installed from Corel WordPerfect Office 2000
Professional.
See your reference manual for
hardware considerations that apply to your specific hardware
setup.
