A DBS-based service is a generic name for a CygNet service that is structurally a database-type service, but is primarily classified by its operational service type (for example, administrative, current value, database, measurement, or real-time) in CygNet Software and in this document. DBS-based services include all of the database services, and several of the administrative and real-time services.
All of the database-type services are collectively known as "DBS-based services" in CygNet Software. Some of these services are considered both structurally and operationally to be Database Services. This includes the Device Definition Service (DDS), Facility Service (FAC), Group Service (GRP), Master Scheduling Service (MSS), Point Service (PNT), Table Reference Service (TRS), and an optional Generic Database Service (DBS).
Several other CygNet services are also database-type services according to their structural service type, but are primarily classified by their operational service type. This includes the Access Control Service (ACS), Audit Service (AUD), BLOB Storage Services (APPS and BSS), Event Logging Services (ELS and ELSALM), General Notification Service (GNS), and the Note Service (NOTE). These additional services are operationally considered Administrative Services (ACS, AUD, APPS, BSS) and Real-Time Services (ELS, ELSALM, GNS, NOTE, VHS).
The following table lists all the CygNet DBS-based services, and their operational type.

All DBS-based services use the same database engine, and have very similar configuration parameters and security administration.
Each type of DBS has a unique database schema. This is defined in the Data Dictionary Language (.ddl) file. The .ddl file also defines the indexes for the service. The indexes are useful for searching the database. Also see Adding a New Index to a CygNet DBS-Based Service.
Note: You can view the contents of the .ddl file, but do not edit the file.
All DBS-based services use the same data storage technology. See Data Storage for DBS-Based Services for more information.
Most DBS-based services use the same procedure to search the database record. See Searching for a Record in the CygNet Explorer section for more information.
