    <p>I know nothing about Pentaho and I just want to know whether it can do my job before I commit a lot of time to learn it. </p> <p>Can Pentaho be used as an XML ETL tool? Can it achieve arbitrary transformation? A typical transformation would be to collapse XML element "Company" and its child element "Employee" into the same "Employee" table, but this is just the simplest transformation and there are infinite other possibilities. For example, to import following XML into our database:</p> <pre><code> &lt;Root&gt; &lt;OrdersByCustomer&gt; &lt;CustomerInfo&gt; &lt;Customer&gt; &lt;CustomerID&gt;1234&lt;/CustomerID&gt; ... &lt;/Customer&gt; &lt;Address&gt;...&lt;/Address&gt; &lt;/CustomerInfo&gt; &lt;Orders&gt; &lt;Order&gt;...&lt;/Order&gt; &lt;Order&gt;...&lt;/Order&gt; &lt;Order&gt;...&lt;/Order&gt; &lt;/Orders&gt; &lt;/ OrdersByCustomer&gt; &lt;/Root&gt; </code></pre> <p>I need to pickup the CustomerID and insert it together with the data inside XML element "Order". </p> <p>Can Pantaho do such infinite and arbitrary transformation? Or do I have to cut my own code?</p> <p>If the answer to the above question is yes, then, two more questions:</p> <ol> <li><p>Is Pentaho symmetric and bidirectional? We not only need to import XML into our database, we also need to generate XML from data in our database. Can Pentaho do that?</p></li> <li><p>If the answer is again yes, I know Pentaho is a framework and there are books written about it. Do I need to learn the whole framework, or can I just install it, spend half a day to only learn the XML ETL part, and start using it?</p></li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
