Oracle Data Integrator ETL からStreak データ連携

この記事では、Oracle Data Integratorを使用してStreak data をデータウェアハウスに転送する方法を説明します。

Streak への接続にJDBC 標準を使用して既存のスキルを活用します。 CData JDBC Driver for Streak は、Oracle Data Integrator(ODI)などのETL ツールへの統合によって、リアルタイムのStreak data をデータウェアハウス、ビジネスインテリジェンス、およびビッグデータテクノロジに連携します。

JDBC 接続を使用すると、ODI 内の他のデータベースと同じようにStreak を使用できます。RDBMS やフラットファイルを使用する代わりに、ドライバーを使用してリアルタイムでStreak API に直接連携できます。

ここでは、JDBC を利用したStreak - Oracle のETL 連携を行います。Streak エンティティのデータモデルをリバースエンジニアリングした後、マッピングを作成してだdata loading strategy を選択します。ドライバーはSQL-92 をサポートしているため、この最後の手順は組み込みSQL からSQL Loading を選択することで簡単に行えます。

ドライバーをインストール

To install the driver, copy the driver JAR and .lic file, located in the installation folder, into the ODI userlib directory:

On Unix: ~/.odi/oracledi/userlib On Windows: %APPDATA%\Roaming\odi\oracledi\userlib

Restart ODI to complete the installation.

モデルのリバースエンジニアリング

Reverse engineering the model retrieves metadata about the driver's relational view of Streak data.After reverse engineering, you can query real-time Streak data and create mappings based on Streak tables.

  1. In ODI, connect to your repository and click New -> Model and Topology Objects.
  2. On the Model screen of the resulting dialog, enter the following information:
    • Name:Enter Streak.
    • Technology:Select Generic SQL.
    • Logical Schema:Enter Streak.
    • Context:Select Global.
  3. On the Data Server screen of the resulting dialog, enter the following information:
    • Name:Enter Streak.
    • Driver List:Select Oracle JDBC Driver.
    • Driver:Enter cdata.jdbc.streak.StreakDriver
    • URL:Enter the JDBC URL containing the connection string.

      Use the following steps to generate a new API key for authenticating to Streak.

      1. Navigate to Gmail
      2. Click on the Streak dropdown to the right of the search bar
      3. Select the Integrations button. This will open a window where you can view existing integrations and create new API keys.
      4. Under the Streak API section of integrations, click the button to Create New Key.

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

      java -jar cdata.jdbc.streak.jar

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

      Below is a typical connection string:

      jdbc:streak:ApiKey=8c84j9b4j54762ce809ej6a782d776j3;
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter Streak.
    • Schema (Work Schema):Enter Streak.
  5. In the opened model click Reverse Engineer to retrieve the metadata for Streak tables.

Streak Data を編集して保存

After reverse engineering you can now work with Streak data in ODI. To view Streak data, expand the Models accordion in the Designer navigator, right-click a table, and click View data.

ETL プロジェクトを作成

Follow the steps below to create an ETL from Streak.You will load Users entities into the sample data warehouse included in the ODI Getting Started VM.

  1. Open SQL Developer and connect to your Oracle database.Right-click the node for your database in the Connections pane and click new SQL Worksheet.

    Alternatively you can use SQLPlus.From a command prompt enter the following:

    sqlplus / as sysdba
  2. Enter the following query to create a new target table in the sample data warehouse, which is in the ODI_DEMO schema.The following query defines a few columns that match the Users table in Streak: CREATE TABLE ODI_DEMO.TRG_USERS (EMAIL NUMBER(20,0),UserKey VARCHAR2(255));
  3. In ODI expand the Models accordion in the Designer navigator and double-click the Sales Administration node in the ODI_DEMO folder.The model is opened in the Model Editor.
  4. Click Reverse Engineer.The TRG_USERS table is added to the model.
  5. Right-click the Mappings node in your project and click New Mapping.Enter a name for the mapping and clear the Create Empty Dataset option.The Mapping Editor is displayed.
  6. Drag the TRG_USERS table from the Sales Administration model onto the mapping.
  7. Drag the Users table from the Streak model onto the mapping.
  8. Click the source connector point and drag to the target connector point.The Attribute Matching dialog is displayed.For this example, use the default options.The target expressions are then displayed in the properties for the target columns.
  9. Open the Physical tab of the Mapping Editor and click USERS_AP in TARGET_GROUP.
  10. In the USERS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

You can then run the mapping to load Streak data into Oracle.
