• Filtering Data– One of the most important feature of any

database application is the filtering of data. The Crash Record System provides many ways of filtering data.

– Appendix A of the manual provides a detailed explanation of filtering data with many examples.

JB Technology Inc.

Crash Record System

The following slides will illustrate the five ways to filter the data.

Crash Record System

• Standard Filter– The most common way to filter data. Using

drop down lists, database fields can be selected with valid options with minimal user input.

JB Technology Inc.

Crash Record System

The above Standard Filter will display only Rear-End crashes.

Crash Record System

JB Technology Inc.

This Standard Filter will display Rear End crashes that occurred after 5:00 pm in the afternoon.

Crash Record System

• Quick Filter– Many times crash records are to be filtered by

either the report number,date of the crash, or the case number. The Quick Filter provides the means to accomplish a quick filter.

JB Technology Inc.

Crash Record System
