MicroStrategy でCData JDBC Driver for SFTP を使ってみた

CData JDBC Driver for SFTP を使用して、MicroStrategy Developer からSFTP data にデータ連携。

MicroStrategyは、データ駆動型のイノベーションを可能にする分析およびモビリティプラットフォームです。MicroStrategy をCData JDBC Driver for SFTP と組み合わせると、MicroStrategy からリアルタイムSFTP data へのRDB のようなアクセスが可能になり、レポートと分析での利用が可能です。ここでは、MicroStrategy Developer でSFTP のデータベースインスタンスを作成し、SFTP data のウェアハウスカタログを作成します。

CData JDBC ドライバーは、ドライバーに組み込まれた最適化されたデータ処理により、MicroStrategy からリアルタイムSFTP data と接続で高いパフォーマンスを提供します。MicroStrategy からSFTP に複雑なSQL クエリを発行すると、ドライバはフィルタや集計などのサポートされているSQL 操作を直接SFTP にプッシュし、埋め込みSQL エンジンを使用してサポートされていない操作(SQL関数やJOIN 操作)を処理します。ビルトインダイナミックメタデータクエリでは、ネイティブのMicroStrategy データ型を使用してSFTP data を視覚化して分析することができます。

MicroStrategy Developer からSFTP への連携を確立

You can connect to SFTP in MicroStrategy Developer by adding a database instance based on the CData JDBC Driver for SFTP.* Before you begin, you will need to install the JDBC Driver for SFTP 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 SFTP.
  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 SFTP\lib\ on Windows.)
    • Set DRIVER to cdata.jdbc.sftp.SFTPDriver, the driver class.
    • Set URL to the JDBC URL for the SFTP driver, which contains the necessary connection properties.

      SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.

      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 subfolders to report as views.
      • FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
      Stored Procedures are available to download files, upload files, and send protocol commands. See gdatamodel for more on using SQL to interact with the server.

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

      java -jar cdata.jdbc.sftp.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.sftp.SFTPDriver;URL={jdbc:sftp: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 SFTP data from the Warehouse Catalog and Data Import.

ウェアハウスカタログからSFTP Data に接続

Once you have created a database instance based on the JDBC Driver for SFTP, 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 SFTP in MicroStrategy, you can easily create robust visualizations and reports on SFTP data.Read our other articles on connecting to SFTP in MictroStrategy Web and connecting to SFTP in MicroStrategy Desktop for more information.


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