Before you Begin
This 5-minute tutorial shows you how to apply Oracle Analytics repair recommendations to US ZIP code data in your data source.
Background
During data profiling, Oracle Analytics can detect corrupted ZIP codes in a data source and recommend repairing the ZIP codes during data preparation. Some states and postal regions have ZIP codes that start with zeros such as Connecticut, Massachusetts, Maine, Puerto Rico, Virgin Islands, and the Army Post Office Europe. When these ZIP codes are entered as numbers rather than as text, the leading zeros are frequently stripped resulting in corrupted data. Oracle Analytics profiles a sample of the data in the source to determine if there are known patterns to provide recommendations for transforming and enriching the dataset. To repair the ZIP codes, Oracle Analytics reinstates the missing leading zeros, changes the ZIP code column from a number data type to text, and changes the column from treat as measure to treat as attribute.
