Data profiling with DataLever™

Data profiling helps you quickly understand the key properties of your database or data feeds. This in turn helps you plan and make decisions about the kind of data cleanup or further exploration that may be needed. Data profiling should be the first step in any data project, but especially for new or foreign data sources. DataLever has a full set of tools and predefined macros to measure and describe your data.

DataLever's profiling macros can quickly give you information about each column in a table or file, including:

• Null count and percent null
• Unique count and percent unique
• Minimum and maximum values
• Minimum and maximum lengths
• Top/Bottom N values by frequency
• Ranking levels and count intervals
• . . . and more!

In addition to the pre-defined profiling macros, you can tailor your own profiling processes to produce exactly the information you want.
