Provides an overview of the guide.
Pentaho Data Integration (PDI) is a flexible tool that allows you to collect data from disparate sources such as databases, files, and applications, and turn the data into a unified format that is accessible and relevant to end users. PDI provides the Extraction, Transformation, and Loading (ETL) engine that facilitates the process of capturing the right data, cleansing the data, and storing the data using a uniform and consistent format.
PDI provides support for slowly changing dimensions, and surrogate key for data warehousing, allows data migration between databases and application, is flexible enough to load giant datasets, and can take full advantage of cloud, clustered, and massively parallel processing environments. You can cleanse your data using transformation steps that range from very simple to very complex. Finally, you can leverage ETL as the data source for Pentaho Reporting.
Common Uses of Pentaho Data Integration Include:
- Data migration between different databases and applications
- Loading huge data sets into databases taking full advantage of cloud, clustered and massively parallel processing environments
- Data Cleansing with steps ranging from very simple to very complex transformations
- Data Integration including the ability to leverage real-time ETL as a data source for Pentaho Reporting
- Data warehouse population with built-in support for slowly changing dimensions and surrogate key creation (as described above)
