Use the CData JDBC Driver for Lohaco to create a virtual data source for Lohaco data in the Denodo Virtual DataPort Administrator.

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for Lohaco, Denodo users can work with live Lohaco data alongside other enterprise data sources. This article walks through creating a virtual data source for Lohaco in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Lohaco data. When you issue complex SQL queries to Lohaco, the driver pushes supported SQL operations, like filters and aggregations, directly to Lohaco and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Lohaco data using native data types.

Create a Lohaco Virtual Port

To connect to live Lohaco data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

  1. Download the CData JDBC Driver for Lohaco installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Lohaco\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-lohaco-19).
  3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
  4. Right-click "admin" and select New -> Data source -> JDBC.
  5. Configure the JDBC Connection:
    • Name: your choice, e.g.: lohaco
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-lohaco-19
    • Driver class: cdata.jdbc.lohaco.LohacoDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,


      Information on creating the Database URI follows:

      Built-In Connection String Designer

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

      java -jar cdata.jdbc.lohaco.jar

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

      Lohaco に接続する場合は、 SellerId、SSLClientCert、およびSSLClientCertType が必要です。

      Lohaco へのアクセスの設定

      SellerId、SSLClientCert、およびSSLClientCertType を取得するには、以下の手順に従ってください。

      • 「API 認証について」を参照して公開鍵と秘密鍵を生成します。
      • Lohaco ストアクリエイターにログインして、[設定]メニューの[証明書設定]に移動します。
      • [証明書を登録]をクリックして[公開鍵]、[許可IPアドレス]、[有効期限]を入力します。

      Lohaco アカウントの認証


      • SellerId:接続先のLohaco Store ID を設定。
      • SSLClientCert:プライベートキーのファイルパスを設定。
      • SSLClientCertType:値"PEMKEY_FILE" を設定。
  6. Click the "Test connection" button to confirm the configuration and click Save.

View Lohaco Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of Lohaco data for use in the Denodo Platform.

  1. Click the "Create base view" button in the newly created VirtualPort (admin.Lohaco).
  2. Expand the object tree and select the objects (tables) you wish to import.
  3. Click the "Create selected" button to create views of the Lohaco data.
    Optional: Click "Create associations from foreign keys" to define relationships between the objects.
  4. With the view(s) created, navigate to a table (cdata_lohaco_items) in the Server Explorer and double-click the selected table.
  5. In the new tab, click "Execution panel" to open a query panel.
  6. Customize the query in the "Execute" tab or use the default:
    SELECT * FROM cdata_lohaco_items CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
  7. Click Execute to view the data.

With the base view created, you can now work with live Lohaco data like you would any other data source in Denodo Platform, for example, querying Lohaco in the Denodo Data Catalog.
