Tao 3.3 - Database / Tables - Where Items, Tests etc. are saved

edited November 2019 in Developers


I have just started using Tao 3.3.

Windows 10
WAMP Server + MySQL

I have created Items, Tests etc. But do not identify in which table it is stored. Please tell me how this is saved in the database and its corresponding table names.

I am waiting for the reply.

Regards & Thanks,


  • Data is split between the database and generis. The database schema can be found here

    The content for the Items themselves is stored in XML format within the data directory.

    As per this URL I do not find the table 'extensions' in my database, but other tables 'models' and 'statements' are available along with other 9 tables, altogether there are total 11 tables.

    I do not understand what type of data is stored in these tables.

    I found the below folders.

    Do you mean these folders with xml files inside it? I found the names of items, tests etc. are available in these files.

    1. Where are other information such as Test-takers, Groups, Deliveries, Results are stored?
    2. Is there any information available about database? Nothing is available in user guide

    I am waiting for the reply and help.

  • Please take a look at:

    Armed with this knowledge take a look at the "statements" table, which is an implementation of RDF in a SQL database. Here you can find item and test metadata and references to the filesystem.

    The results are stored in 2 dedicated tables: results_storage and variables_storage

  • Hi Joel.

    Many thanks for the reply and referencing the resources. I do not aware about this. Now it has stated clearing to me.

    Is there anything stored in files physically?

    Can you tell me how do I use Tao's library in my own PHP code?

    I am waiting for the reply. Please help.

    Regards & Thanks,

  • As mentioned there is data stored physically in files under your data location

  • In my installation folder, I find the below folders.


    Here I find the information I saved using Tao admin for items and test. But where do I get the result information.

    Please help amy. Thanks in advane.
