MicroStrategy でCData JDBC Driver for SQL Analysis Services を使ってみた

CData JDBC Driver for SQL Analysis Services を使用して、MicroStrategy Developer からSQL Analysis Services 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 SQL Analysis Services と組み合わせると、MicroStrategy からリアルタイムSQL Analysis Services 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SQL Analysis Services のデータベースインスタンスを作成し、SQL Analysis Services 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SQL Analysis Services data と接続で高いパフォーマンスを提供します。MicroStrategy からSQL Analysis Services 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SQL Analysis Services 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SQL Analysis Services data を視覚化して分析することができます。

MicroStrategy Developer からSQL Analysis Services への連携を確立

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

      To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.

      To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

      • HTTP Authentication

        Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.

      • Windows (NTLM)

        Set the Windows User and Password and set AuthScheme to "NTLM".

      • Kerberos and Kerberos Delegation

        To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.

      • SSL/TLS:

        By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

      You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

      See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

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

      java -jar cdata.jdbc.ssas.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.ssas.SSASDriver;URL={jdbc:ssas:User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;};
  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 SQL Analysis Services data from the Warehouse Catalog and Data Import.

ウェアハウスカタログからSQL Analysis Services Data に接続

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


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