Definition: An ETL process data to load into the database from a flat file A. Extract B. Transform C. Load 1. PGLoader - Load .csv file 2. Benetl 1.8 - Load .txt or .csv or .xls file 3. Talend Open Studio => http://www.talend.com/index.php 4. Pentaho Kettle => http://kettle.pentaho.com/ 5. Visual Importer => Data can be imported from flat files,Excel.MS Access,Oracle.Mysql.Interbase,PostgreSQL,oleDB,ODBC and DBF files. 6. CloverETL => http://en.wikipedia.org/wiki/CloverETL Both [3 &4] of these ETL solutions have a lot of the same types of features: - Both are Java based and run on Linux and Windows (Talend is Eclipse-based) - Visual designers for creating the transformations - Connectivity for a myriad of databases, including all the big DBs, text formats, etc. - Supports distributing jobs across multiple servers if you are doing serious lifting - Excellent error handling and error notification systems - Active and helpful forums (Kettle is older and seems to have a larger community however) - Free and open source - They are complex enough to handle a lot of tasks, but not so much as to kill you - There are versions of both (GeoKettle and Spatial Data Integrator) that are tailored for GIS Thanks & Regards Raghu Ram
