Oracle Data Integrator ETL からEpicor ERP データ連携

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

Epicor ERP 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 Epicor ERP 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Epicor ERP 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Epicor ERP 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Epicor ERP API に直接連携できます。

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

      To successfully connect to your ERP instance, you must specify the following connection properties:

      • Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
      • ERPInstance: the name of your ERP instance.
      • User: the username of your account.
      • Password: the password of your account.
      • Service: the service you want to retrieve data from. For example, BaqSvc.

      In addition, you may also set the optional connection properties:

      • ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
      • ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
      • Company: Required if you set the ApiVersion to v2.

      ビルトイン接続文字列デザイナー

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

      java -jar cdata.jdbc.epicorerp.jar

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

      Below is a typical connection string:

      jdbc:epicorerp:Service=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;InitiateOAuth=GETANDREFRESH
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter EpicorERP.
    • Schema (Work Schema):Enter EpicorERP.
  5. In the opened model click Reverse Engineer to retrieve the metadata for Epicor ERP tables.

Epicor ERP Data を編集して保存

After reverse engineering you can now work with Epicor ERP data in ODI. To edit and save Epicor ERP 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 Epicor ERP.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 Epicor ERP: CREATE TABLE ODI_DEMO.TRG_CUSTOMERS (COMPANY NUMBER(20,0),CustNum 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 Epicor ERP 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 Epicor ERP data into Oracle.
