HarperDB ODBC Driver

The HarperDB ODBC Driver is a powerful tool that allows you to connect with live data from HarperDB, directly from any applications that support ODBC connectivity.

Access HarperDB data like you would a relational database - read, write, and update HarperDB through a standard ODBC Driver interface.



Create data visualizations with HarperDB data in Power Map.

The CData ODBC Driver for HarperDB is easy to set up and use with self-service analytics solutions like Power BI: Microsoft Excel provides built-in support for the ODBC standard. This article shows how to load the current HarperDB data into Excel and start generating location-based insights on HarperDB data in Power Map.

Create an ODBC Data Source for HarperDB

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.

Set the Server, User, and Password connection properties to connect to HarperDB. Set UseSSL to secure connections with TLS/SSL.

When you configure the DSN, 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.

Import HarperDB Data into Excel

You can import data into Power Map either from an Excel spreadsheet or from Power Pivot. For a step-by-step guide to use either method to import HarperDB data, see the "Using the ODBC Driver" section in the help documentation.

Geocode HarperDB Data

After importing the HarperDB data into an Excel spreadsheet or into PowerPivot, you can drag and drop HarperDB entities in Power Map. To open Power Map, click any cell in the spreadsheet and click Insert -> Map.

In the Choose Geography menu, Power Map detects the columns that have geographic information. In the Geography and Map Level menu in the Layer Pane, you can select the columns you want to work with. Power Map then plots the data. A dot represents a record that has this value. When you have selected the geographic columns you want, click Next.

Select Measures and Categories

You can then simply select columns: Measures and categories are automatically detected. The available chart types are Stacked Column, Clustered Column, Bubble, Heat Map, and Region.
