MicroStrategy でCData JDBC Driver for Google Sheets を使ってみた

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

MicroStrategy Developer からGoogle Sheets への連携を確立

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

      You can connect to a spreadsheet by providing authentication to Google and then setting the Spreadsheet connection property to the name or feed link of the spreadsheet. If you want to view a list of information about the spreadsheets in your Google Drive, execute a query to the Spreadsheets view after you authenticate.

      ClientLogin (username/password authentication) has been officially deprecated since April 20, 2012 and is now no longer available. Instead, use the OAuth 2.0 authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

      OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

      See the Getting Started chapter in the help documentation to connect to Google Sheets from different types of accounts: Google accounts, Google Apps accounts, and accounts using two-step verification.

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

      java -jar cdata.jdbc.googlesheets.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.googlesheets.GoogleSheetsDriver;URL={jdbc:googlesheets:Spreadsheet=MySheet;};
  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 Google Sheets data from the Warehouse Catalog and Data Import.

ウェアハウスカタログからGoogle Sheets Data に接続

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


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