Setting up a distant database - 7.1

Talend Real-time Big Data Platform Studio User Guide

Talend Real-Time Big Data Platform
Talend Studio
Design and Development

Talend DQ Portal is deprecated from Talend 7.1 onwards. You can connect the data quality data mart to your own reporting tool.

By default, your Talend Studio stores reports and analyses in an embedded HSQL database. Usually, you will want to set up a distant database accessible by other users and thus share the results of the analyses and further exploit them via Talend DQ Portal .

From the Profiling perspective Talend Studio, you can set up a distant database. This database will be the by-default distant database that stores all reports and analysis results unless you decide to store individual reports in a database different from this one. For further information, see Setting up a database for an individual report.

For further information about Talend DQ Portal, see the Talend DQ Portal User and Administrator Guide. For further information on installing Talend DQ Portal, see the Talend Installation and Upgrade Guide .

Before you begin

You have selected the Profiling perspective of Talend Studio.


  1. In the menu bar, select Window > Preferences to display the Preferences window.
  2. Start typing Reporting in the filter field and then select Reporting from the list to open the Reporting page.
  3. In the DB Type list, select the name of the database you want to define.
    By default, your studio stores reports and analysis results in an embedded HSQL database. You cannot share reports and analysis results when stored in the HSQL database.
  4. Define the connection parameters in the individual connection fields or directly in the Url field.
    When you modify any parameter in the Url field, it is modified automatically in the individual fields and vice versa.
    In the DB Name, you must use the same database name that is defined when installing Talend DQ Portal. For further information, see the Talend Installation and Upgrade Guide .
    For MySQL:
    In the DB Name field, you can either:
    • enter a database name (catalog) that does not exist in your database. The studio will create a new catalog and generate all the required tables to store your analyses and reports, or,
    • use the by-default database name (talend_dq). In this database, you can have access to all analyses and results of generated reports.
    MySQL database names with a dot "." are allowed.
    When using the IPV6 address format for a local MySQL, configure the database connection using the logical hostname, localhost, and map this in the hosts file to the IPV6 local address, [::1]. Otherwise the startup of the Portal fails.
    For Oracle:
    • Fill the SID, the Service Name or the OCI Service Namefield with the name of an existing database.

    • Fill the Schema field with an Oracle schema to which the specified user in the User field has access, or leave it blank. If you leave this field blank, your reports will be written to the default schema of the defined user.

    For PostgreSQL or Microsoft SQL Server, fill in the connection information to the database. You can use only the default schemas of PostgreSQL or Microsoft SQL Server when you create the datamart on them.
    PostgreSQL and Microsoft SQL Server database names with a dot "." or an hyphen "-" are allowed.
    For Microsoft SQL Server, If you want to connect through Windows authentication, leave the User and Password fields empty. For more information about setting up a connection to a Microsoft SQL Server database, see What you need to know about some databases.
    Warning: To enable writing reports to the defined database, make sure that the specified user has enough system privileges. For further information, see the Talend Installation and Upgrade Guide.
  5. Enter your login information to the database in the corresponding fields.
  6. If needed, click Export as context and follow the steps in the wizard to export the datamart connection and the path of the report folder and logo as a context.
    You can click Revert Context to switch the connection back to its initial state.
  7. Either:
    • Click Apply to report editors... to open a list from which you can select the reports which results you want to store in the defined datamart or context connection. For further information, see Migrating the database for a group of reports.
    • Click Apply to store the results of all analyses and reports in the defined database.
  8. Click OK to validate the changes and close the Preferences window.
    When the version of the distant database created from the Profiling perspective of Talend Studio is older than that of the Talend Studio, a pop-up message is displayed to ask you if you want a database upgrade. For more information, see Migrating the distant database.
