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

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

MicroStrategy Developer からCSV への連携を確立

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

      The DataSource property must be set to a valid local folder name.

      Also, specify the IncludeFiles property to work with text files having extensions that differ from .csv, .tab, or .txt. Specify multiple file extensions in a comma-separated list. You can also set Extended Properties compatible with the Microsoft Jet OLE DB 4.0 driver. Alternatively, you can provide the format of text files in a Schema.ini file.

      Set UseRowNumbers to true if you are deleting or updating in CSV. This will create a new column with the name RowNumber which will be used as key for that table.

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

      java -jar cdata.jdbc.csv.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.csv.CSVDriver;URL={jdbc:csv:DataSource=MyCSVFilesFolder;};
  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 CSV data from the Warehouse Catalog and Data Import.

ウェアハウスカタログからCSV Data に接続

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


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