Tool for Data Preparation, Preprocessing and Exploration for Data Mining and Data Analysis

Data Cleaning

Data cleaning facilities include character removal, text replacement, and date conversion.

Data Import/Export

DataPreparator can be used to import data from a database and export them to a file and vice versa. 

Data Integration

Two operators, Append and Merge, can be used to combine data from different data sources.

Data Reduction

Data reduction can be achieved using sampling and record selection.

Data Transformation

DataPreparator can be used to preprocess data for data mining. It transforms training data using a series of transformations and in the process creates a model which can be used to transform corresponding test/execution data.

DataPreparator provides many operators for transforming data. See Features.

Data Visualization

Data visualization can be performed using a variety of statistical plots.  See Features for details.
