DiffixValueGenerator
The ValueGenerator is a tool to generate synthetic data values from a database column using Diffix as offered by Aircloak.
ValueGenerator queries the column through Diffix and stores certain column attributes. Subsequently, individual values may be requested that are syntactically similar to the original data. If the data is numeric, then values within a given range may be requested. If there are relatively few distinct values in the column, then the synthetic values are identical to those in the column. This tool does not preserve the statistical attributes of the original data.
