    Hi,

    a bit more information about your setup and your requirements and objectives would be helpful to give you a decent answer. More generally speaking, I'd like you to direct you to the video tutorials on our website. They explain the basic concepts of RapidMiner, and there is also a series specially tailored to text mining.
    To get the data from a database into RapidMiner, you need to configure a database connection under the tools menu (Manage Database connection), and then you can use the Read Database operator to actually import data.

    If you have any problems, please let us know about the exact step where you can't progress.

    Best regards,
    Marius

    Hi Prashu,

    did you already watch the video tutorials on http://rapid-i.com/content/view/189/212/lang,en/ ?

    You said you already have a process, please post it as described in my signature, and describe what you expect it to do.

    And finally, it may be a good idea to post some lines of your tables as an example, such that we can better understand with which kind of data we are dealing.

    Best regards,
    Marius
