Oracle Data Integrator ETL からBigCommerce データ連携

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

BigCommerce への読み書きにJDBC 標準を使用して既存のスキルを活用します。 CData JDBC Driver for BigCommerce 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BigCommerce 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BigCommerce 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BigCommerce API に直接連携できます。

ここでは、JDBC を利用したBigCommerce - Oracle のETL 連携を行います。BigCommerce 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 BigCommerce data.After reverse engineering, you can query real-time BigCommerce data and create mappings based on BigCommerce 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 BigCommerce.
    • Technology:Select Generic SQL.
    • Logical Schema:Enter BigCommerce.
    • Context:Select Global.
  3. On the Data Server screen of the resulting dialog, enter the following information:
    • Name:Enter BigCommerce.
    • Driver List:Select Oracle JDBC Driver.
    • Driver:Enter cdata.jdbc.bigcommerce.BigCommerceDriver
    • URL:Enter the JDBC URL containing the connection string.

      BigCommerce authentication is based on the standard OAuth flow. To authenticate, you must initially create an app via the Big Commerce developer platform where you can obtain an OAuthClientId, OAuthClientSecret, and CallbackURL. These three parameters will be set as connection properties to your driver.

      Additionally, in order to connect to your BigCommerce Store, you will need your StoreId. To find your Store Id please follow these steps:

      1. Log in to your BigCommerce account.
      2. From the Home Page, select Advanced Settings > API Accounts.
      3. Click Create API Account.
      4. A text box named API Path will appear on your screen.
      5. Inside you can see a URL of the following structure: https://api.bigcommerce.com/stores/{Store Id}/v3.
      6. As demonstrated above, your Store Id will be between the 'stores/' and '/v3' path paramters.
      7. Once you have retrieved your Store Id you can either click Cancel or proceed in creating an API Account in case you do not have one already.

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

      java -jar cdata.jdbc.bigcommerce.jar

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

      Below is a typical connection string:

      jdbc:bigcommerce:OAuthClientId=YourClientId; OAuthClientSecret=YourClientSecret; StoreId='YourStoreID'; CallbackURL='http://localhost:33333'InitiateOAuth=GETANDREFRESH
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter BigCommerce.
    • Schema (Work Schema):Enter BigCommerce.
  5. In the opened model click Reverse Engineer to retrieve the metadata for BigCommerce tables.

BigCommerce Data を編集して保存

After reverse engineering you can now work with BigCommerce data in ODI. To edit and save BigCommerce data, expand the Models accordion in the Designer navigator, right-click a table, and click Data.Click Refresh to pick up any changes to the data.Click Save Changes when you are finished making changes.

ETL プロジェクトを作成

Follow the steps below to create an ETL from BigCommerce.You will load Customers 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 Customers table in BigCommerce: CREATE TABLE ODI_DEMO.TRG_CUSTOMERS (LASTNAME NUMBER(20,0),FirstName 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_CUSTOMERS 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_CUSTOMERS table from the Sales Administration model onto the mapping.
  7. Drag the Customers table from the BigCommerce 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 CUSTOMERS_AP in TARGET_GROUP.
  10. In the CUSTOMERS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

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