DBArtisan でJSON Services に連携

DBArtisan のウィザードを使って、JSON services をデータソースとして連携利用。

CData ODBC Driver for JSON は、DBArtisan などのデータベースツールとJSON services を連携し、RDB のような感覚でJSON データを扱えます。 本記事では、DBArtisan 上でJSON データソースを作成する方法とクエリの実行方法を説明します。

DBArtisan Project にJSON Services を連携する

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

You can then 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 ODBC.
  3. Enter a name for the data source and select the DSN.
  4. 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.
