Connection details for query managers are defined using system elements, which allows defining them once and reusing them across different state and query elements.
Query managers connect to a specific system, translate Rierino query format to query statements in that system's domain specific language and return results in JSON form. Typically, a separate query manager is defined for each database.
It is possible to define any number and type of new query managers with specialized configurations, and typical managers deployed with Rierino are described in this section. A number of settings are shared across all query manager types:
