Apache Derby Connector for SSASApache Derby Connector enables you to connect to Apache Derby, a lightweight, open-source relational database management system (RDBMS). In this article you will learn how to quickly and efficiently integrate Apache Derby data in SSAS without coding. We will use high-performance Apache Derby Connector to easily connect to Apache Derby and then access the data inside SSAS. Let's follow the steps below to see how we can accomplish that! Apache Derby Connector for SSAS is based on ZappySys JDBC Bridge Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few. |

Prerequisites
Before we begin, make sure you meet the following prerequisite:
-
Java 8 Runtime Environment (JRE) installed. It is recommended to use these distributions:
Download Apache Derby JDBC driver
To connect to Apache Derby in SSAS, you will have to download JDBC driver for it, which we will use in later steps. Let's perform these little steps right away:
- Visit Apache Derby website.
-
Follow the instructions there, download the JDBC drivers, and save them locally.
It is recommended to use JDBC driver compiled for Java 8, if possible.
- Done! That was easy, wasn't it? Let's proceed to the next step.
Create Data Source in ZappySys Data Gateway based on JDBC Bridge Driver
-
Download and install ODBC PowerPack.
-
Search for gateway in start menu and Open ZappySys Data Gateway:
-
Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
-
Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys JDBC Bridge Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

Now, we need to configure the JDBC connection in the new ODBC data source. Simply enter the Connection string, credentials, configure other settings, and then click Test Connection button to test the connection:
ApacheDerbyDSNjdbc:derby://hostname:1527/mydatabaseorg.apache.derby.jdbc.ClientDriverD:\Apache\derby\lib\derbyclient.jaradmin**************[]For Client/server Environment, use these values when setting parameters:
-
Connection string :jdbc:derby://hostname:1527/mydatabase
-
Driver class :org.apache.derby.jdbc.ClientDriver
-
JDBC driver file(s) :D:\Apache\derby\lib\derbyclient.jar
-
User name :admin
-
User password :**************
-
Connection parameters :[]
For Embedded Environment, use these values when setting parameters:
-
Connection string :jdbc:derby:c:\apache\derby\databases\mydatabase
-
Driver class :org.apache.derby.jdbc.EmbeddedDriver
-
JDBC driver file(s) :D:\Apache\derby\lib\derby.jar
-
-
You should see a message saying that connection test is successful:
Otherwise, if you are getting an error, check out our Community for troubleshooting tips.
-
We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:
ApacheDerbyDSNSELECT * FROM "APP"."ORDERS"
SELECT * FROM "APP"."ORDERS"
You can also click on the <Select Table> dropdown and select a table from the list.The ZappySys JDBC Bridge Driver acts as a transparent intermediary, passing SQL queries directly to the Trino JDBC driver, which then handles the query execution. This means the Bridge Driver simply relays the SQL query without altering it.
Some JDBC drivers don't support
INSERT/UPDATE/DELETE
statements, so you may get an error saying "action is not supported" or a similar one. Please, be aware, this is not the limitation of ZappySys JDBC Bridge Driver, but is a limitation of the specific JDBC driver you are using. -
Click OK to finish creating the data source.
Read Apache Derby data in SSAS cube
With the data source created in the Data Gateway (previous step), we're now ready to read Apache Derby data in an SSAS cube. Before we dive in, open Visual Studio and create a new Analysis Services project. Then, you're all set!
Create data source based on ZappySys Data Gateway
Let's start by creating a data source for a cube, based on the Data Gateway's data source we created earlier. So, what are we waiting for? Let's do it!
-
Create a new data source:
-
Once a window opens,
select Create a data source based on an existing or new connection option and
click New...:
-
Here things become a little complicated, but do not despair, it's only for a little while.
Just perform these little steps:
- Select Native OLE DB\SQL Server Native Client 11.0 as provider.
- Enter your Server name (or IP address) and Port, separated by a comma.
- Select SQL Server Authentication option for authentication.
- Input User name which has admin permissions in the ZappySys Data Gateway.
- In Database name field enter the same data source name you use in the ZappySys Data Gateway.
- Hopefully, our hard work is done, when we Test Connection.
ApacheDerbyDSNApacheDerbyDSNIf SQL Server Native Client 11.0 is not listed as Native OLE DB provider, try using these:- Microsoft OLE DB Driver for SQL Server
- Microsoft OLE DB Provider for SQL Server
-
Indeed, life is easy again:
Add data source view
We have data source in place, it's now time to add a data source view. Let's not waste a single second and get on to it!
-
Start by right-clicking on Data Source Views and then choosing New Data Source View...:
-
Select the previously created data source and click Next:
- Ignore the Name Matching window and click Next.
-
Add the tables you will use in your SSAS cube:
For cube dimensions, consider creating a Virtual Table in the Data Gateway's data source. Use the
DISTINCT
keyword in theSELECT
statement to get unique values from the facts table, like this:SELECT DISTINCT Country FROM Customers
For demonstration purposes we are using sample tables which may not be available in Apache Derby. -
Review your data source view and click Finish:
-
Add the missing table relationships and you're done!
Create cube
We have a data source view ready to be used by our cube. Let's create one!
-
Start by right-clicking on Cubes and selecting New Cube... menu item:
-
Select tables you will use for the measures:
-
And then select the measures themselves:
-
Don't stop and select the dimensions too:
-
Move along and click Finish before the final steps:
-
Review your cube before processing it:
-
It's time for the grand finale! Hit Process... to create the cube:
-
A splendid success!
Execute MDX query
The cube is created and processed. It's time to reap what we sow! Just execute an MDX query and get Apache Derby data in your SSAS cube:

Conclusion
In this article we showed you how to connect to Apache Derby in SSAS and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys JDBC Bridge Driver allows you to connect not only to Apache Derby, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).
We encourage you to download Apache Derby Connector for SSAS and see how easy it is to use it for yourself or your team.
