DBArtisan でJDBC 経由でJSON Services をデータ連携利用

DBArtisan のウィザードを使用して、JSON のJDBC データソースを作成します。

CData JDBC Driver for JSON は、データベースとしてJSON services に連携できるようにすることで、JSON services をDBArtisan などのデータベース管理ツールにシームレスに連携します。ここでは、DBArtisan でJSON のJDBC ソースを作成する方法を説明します。データを直観的に標準SQL で実行できます。

JSON Services をDBArtisan Projects に連携

Follow the steps below to register JSON services as a database instance in your project:

  1. In DBArtisan, click Data Source -> Register Datasource.
  2. Select Generic JDBC.
  3. Click Manage.
  4. In the resulting dialog, click New.Enter a name for the driver and click Add.In the resulting dialog, navigate to the driver JAR.The driver JAR is located in the lib subfolder of the installation directory.
  5. In the Connection URL box, enter credentials and other required connection properties in the JDBC URL.

    See the Getting Started chapter in the data provider documentation to authenticate to your data source: The data provider models JSON APIs as bidirectional database tables and JSON files as read-only views (local files, files stored on popular cloud services, and FTP servers). The major authentication schemes are supported, including HTTP Basic, Digest, NTLM, OAuth, and FTP. See the Getting Started chapter in the data provider documentation for authentication guides.

    After setting the URI and providing any authentication values, set DataModel to more closely match the data representation to the structure of your data.

    The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

    • Document (default): Model a top-level, document view of your JSON data. The data provider returns nested elements as aggregates of data.
    • FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
    • Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

    See the Modeling JSON Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

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

    java -jar cdata.jdbc.json.jar

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

    Below is a typical connection string:

    jdbc:json:URI=C:\people.json;DataModel=Relational;
  6. Finish the wizard to connect to JSON services. JSON entities are displayed in the Datasource Explorer.

You can now work with JSON services as you work with any other database. See the driver help documentation for more information on the queries supported by the JSON API.
