Evernote JDBC Driver

Evernote のNotebooks、Notes、Searches、Tags にデータ連携するJava アプリケーションを簡単に構築。



Use the CData JDBC Driver for Evernote to create a virtual data source for Evernote 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 Evernote, Denodo users can work with live Evernote data alongside other enterprise data sources. This article walks through creating a virtual data source for Evernote in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Evernote data. When you issue complex SQL queries to Evernote, the driver pushes supported SQL operations, like filters and aggregations, directly to Evernote 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 Evernote data using native data types.

Create an Evernote Virtual Port

To connect to live Evernote 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 Evernote 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 Evernote\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-evernote-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.: evernote
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-evernote-19
    • Driver class: cdata.jdbc.evernote.EvernoteDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

      jdbc:evernote:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH

      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 Evernote JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.evernote.jar

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

      Evernote はOAuth 認証標準を利用しています。埋め込みクレデンシャルを使用すると、接続プロパティを設定せずに接続できます。あるいは、アプリを作成してOAuthClientId、OAuthClientSecret、およびCallbackURL 接続プロパティを取得することもできます。認証方法については、ヘルプドキュメントの「OAuth 認証の使用」を参照してください。

  6. Click the "Test connection" button to confirm the configuration and click Save.

View Evernote Data in the VirtualPort Administrator Tool

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

  1. Click the "Create base view" button in the newly created VirtualPort (admin.Evernote).
  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 Evernote 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_evernote_notes) 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_evernote_notes 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 Evernote data like you would any other data source in Denodo Platform, for example, querying Evernote in the Denodo Data Catalog.
