Introduction

Sigma has hundreds of pre-built integrations to data sources providing enterprise-grade security to protect your data. It can provide both off the shelf and develop custom interfaces in line with your organisation’s needs, to enable data transfer to and from data sources. The Sigma Import Agent (SIA) is just one of a number of options that can be provided for importing data.

...

• Configuring Import Agents within Sigma to represent each SIA instance.
• Installing the SIA at each Site and capturing the appropriate Import Agent during the Installation process.
• Configuring schedules within Sigma to import HF data from external systems and linking them to the appropriate Import Agent.
• Configuring channels within Sigma to receive HF data.

How Does the Sigma Import Agent Work?

...

Both the Periodic and Non Periodic Importers use the ExtendedLog table in the TAC MSSQL database to source data for channels. The Continuum Importers support multiple agents, the agent name needs to be included in the DataLoad Id to identify which database should be used.  The system processes all channels where the Data Load ID 1 starts with "tac://". A Continuum Compliant dataload ID will look as follows:

The system then runs the following SQL to get the data for the channel:
