Hey,

 

i have problem. I'm pretty new with HP Vertica and i just tried to create the VMart sample database. After a few hours i finally managed it with the --skip-fs-checks operator.

 

Now I'm trying to create a database schema from an existing sheet.

I already converted the xlsx file into a csv file.

 

My question is now:

Do I have to set up the existing excel schema by myself or is this an automatic vertica task?

Does vertica recognize the database schema and the values?

 

Further more, I have a lot of excel sheets which i have to analyze. All of them have different schemas.

Is this possible in any way with vertica without copying the values by myself into vertica?

 

Thank you in advance and

Kind regards

    Have you looked at using Flex tables and the CSV parser:

     

    https://my.vertica.com/docs/7.2.x/HTML/index.htm#Authoring/FlexTables/FCSVPARSERreference.htm

     

    With flex tables you do not need to define the schema ahead of time. It is based on the data loaded.

     

    See the flex table handbook for more details:

    Thank you very much for your answer.

    Now i had time to try the flex tables.

    I used the fcsv parser to import data into my table. The data is pretty unstructured but i managed to import it.

     

    Now i wanted to ask if its possible to analyze the content (Business Intelligence)

    I want to know if there are similarities in those different csv files.

    Is this possible? If yes, how?

     

    Thank you in advance.

     

    Greetings

    Yes you can analyse , HP Vertica is Big data analytics database.

    if you need graphs or kind of dashboard you can integrate BI tool with HP vertica.
