CData API Server とADO.NET Provider for JSON (もしくは200+ の他のADO.NET Providers) を使って、SAP Lumira にJSON services をフィードして、ビジュアライズを実現できます。コネクターによりリアルタイムデータ連携が可能になり、リフレッシュ操作で最新のデータを取得可能になります。
Follow the steps below to begin producing secure JSON OData services:
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
After you deploy the API Server and the ADO.NET Provider for JSON, provide authentication values and other connection properties needed to connect to JSON by clicking Settings -> Connection and adding a new connection in the API Server administration console.
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.
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.
When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.
You can then choose the JSON entities you want to allow the API Server access to by clicking Settings -> Resources.
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.
Follow the steps below to retrieve JSON services into SAP Lumira. You can execute an SQL query or use the UI.
https://your-server:8032/api.rsc
Select entities in the tree or enter an SQL query. This article imports JSON people entities.
When you click Connect, SAP Lumira will generate the corresponding OData request and load the results into memory. You can then use any of the data processing tools available in SAP Lumira, such as filters, aggregates, and summary functions.
After you have imported the data, you can create data visualizations in the Visualize room. Follow the steps below to create a basic chart.
In the Measures and Dimensions pane, drag measures and dimensions onto the x-axis and y-axis fields in the Visualization Tools pane. SAP Lumira automatically detects dimensions and measures from the metadata service of the API Server.
By default, the SUM function is applied to all measures. Click the gear icon next to a measure to change the default summary.
