Oracle Data Integrator ETL からFedEx データ連携

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

FedEx 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 FedEx 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FedEx 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FedEx 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FedEx API に直接連携できます。

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

      There are five pieces of information needed in order to authenticate its actions with the FedEx service. This information is below.

      • Server: This controls the URL where the requests should be sent. Common testing options for this are: "https://gatewaybeta.fedex.com:443/xml", "https://wsbeta.fedex.com:443/xml", "https://gatewaybeta.fedex.com:443/web-service", and "https://wsbeta.fedex.com:443/web-service"
      • DeveloperKey: This is the identifier part of the authentication key for the sender's identity. This value will be provided to you by FedEx after registration.
      • Password: This is the secret part of the authentication key for the sender's identity. This value will be provided to you by FedEx after registration.
      • AccountNumber: This valid 9-digit FedEx account number is used for logging into the FedEx server.
      • MeterNumber: This value is used for submitting requests to FedEx. This value will be provided to you by FedEx after registration.
      • PrintLabelLocation: This property is required if one intends to use the GenerateLabels or GenerateReturnLabels stored procedures. This should be set to the folder location where generated labels should be stored.

      The Cache Database

      Many of the useful tasks available from FedEx require a lot of data. To ensure this data is easy to input and recall later, utilizes a cache database to make these requests. You must set the cache connection properties:

      • CacheProvider: The specific database you are using to cache with. For example, org.sqlite.JDBC.
      • CacheConnection: The connection string to be passed to the cache provider. For example, jdbc:sqlite:C:\users\username\documents\fedexcache.db

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

      java -jar cdata.jdbc.fedex.jar

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

      Below is a typical connection string:

      jdbc:fedex:Server='https://gatewaybeta.fedex.com:443/xml';DeveloperKey='alsdkfjpqoewiru';Password='zxczxqqtyiuowkdlkn';AccountNumber='110371337';MeterNumber='240134349'; PrintLabelLocation='C:\users\username\documents\mylabels';CacheProvider='org.sqlite.JDBC';CacheConnection='jdbc:sqlite:C:\users\username\documents\fedexcache.db';
  4. On the Physical Schema screen, enter the following information:
    • Schema (Schema):Enter FedEx.
    • Schema (Work Schema):Enter FedEx.
  5. In the opened model click Reverse Engineer to retrieve the metadata for FedEx tables.

FedEx Data を編集して保存

After reverse engineering you can now work with FedEx data in ODI. To edit and save FedEx 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 FedEx.You will load Senders 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 Senders table in FedEx: CREATE TABLE ODI_DEMO.TRG_SENDERS (PHONE 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_SENDERS 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_SENDERS table from the Sales Administration model onto the mapping.
  7. Drag the Senders table from the FedEx 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 SENDERS_AP in TARGET_GROUP.
  10. In the SENDERS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

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