Use the CData JDBC Driver for FTP in MicroStrategy

Connect to FTP data in MicroStrategy Developer using the CData JDBC Driver for FTP.

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData JDBC Driver for FTP, you gain database-like access to live FTP data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for FTP in MicroStrategy Developer and create a Warehouse Catalog for the FTP data.

The CData JDBC Driver offers unmatched performance for interacting with live FTP data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to FTP, the driver pushes supported SQL operations, like filters and aggregations, directly to FTP and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze FTP data using native MicroStrategy data types.

Connect to FTP in MicroStrategy Developer

You can connect to FTP in MicroStrategy Developer by adding a database instance based on the CData JDBC Driver for FTP.* Before you begin, you will need to install the JDBC Driver for FTP on the machine hosting the MicroStrategy Intelligence Server that your instance of MicroStrategy Developer is connected to.

  1. Open MicroStrategy Developer and select a Project Source.
  2. Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
  3. Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
  4. In the database connection wizard, name the connection and create a new Database Login name, setting the user and password for FTP.
  5. On the Advanced tab for the connection wizard, set the additional connection string parameters as follows.
    • Add the JDBC keyword to the connection string.
    • Set MSTR_JDBC_JAR_FOLDER to the path of the directory containing the JAR file for the JDBC driver. (C:\Program Files\CData JDBC Driver for FTP\lib\ on Windows.)
    • Set DRIVER to cdata.jdbc.ftp.FTPDriver, the driver class.
    • Set URL to the JDBC URL for the FTP driver, which contains the necessary connection properties.

      To connect to FTP or SFTP servers, specify at least RemoteHost and FileProtocol. Specify the port with RemotePort.

      Set User and Password to perform Basic authentication. Set SSHAuthMode to use SSH authentication. See the Getting Started section of the data provider help documentation for more information on authenticating via SSH.

      Set SSLMode and SSLServerCert to secure connections with SSL.

      The data provider lists the tables based on the available folders in your FTP server. Set the following connection properties to control the relational view of the file system:

      • RemotePath: Set this to the current working directory.
      • TableDepth: Set this to control the depth of folders to list as views.
      • FileRetrievalDepth: Set this to retrieve and list files recursively from the root table.

      Stored Procedures are available to download files, upload files, and send protocol commands. See the Data Model chapter of the FTP data provider documentation for more information.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the FTP JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.ftp.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

    Typical additional connection string properties follow:

    JDBC;MSTR_JDBC_JAR_FOLDER=PATH\TO\JAR\;DRIVER=cdata.jdbc.ftp.FTPDriver;URL={jdbc:ftp:RemoteHost=MyFTPServer;};
  6. Ensure that you have not selected an ODBC data source (this will trigger MicroStrategy to use the additional connection string parameters to build the database instance) and click OK.
  7. Click OK to close the database instance wizard.
  8. In the Project Source, right-click the project and open the Project configuration.
  9. Navigate to Database Instances, select the newly created database instance, and click OK.
  10. Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.

With the database instance configured, you will now be able to connect to FTP data from the Warehouse Catalog and Data Import.

Connect to FTP Data from the Warehouse Catalog

Once you have created a database instance based on the JDBC Driver for FTP, you can connect to data from the Warehouse Catalog.

  1. Select your project and click Schema -> Warehouse Catalog.
  2. In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
    • To retrieve the list of tables, use the following query: SELECT * FROM SYS_TABLES
    • To retrieve the list of columns for selected tables, use the following query: SELECT DISTINCT CatalogName NAME_SPACE, TableName TAB_NAME, ColumnName COL_NAME, DataTypeName DATA_TYPE, Length DATA_LEN, NumericPrecision DATA_PREC, NumericScale DATA_SCALE FROM SYS_TABLECOLUMNS WHERE TableName IN (#TABLE_LIST#) ORDER BY 1,2,3
  3. Select tables to be used in the project.

Using the CData JDBC Driver for FTP in MicroStrategy, you can easily create robust visualizations and reports on FTP data. Read our other articles on connecting to FTP in MictroStrategy Web and connecting to FTP in MicroStrategy Desktop for more information.


Note: Connecting using a JDBC Driver requires a 3- or 4-Tier Architecture.
