UDA Glossary Terms

ADO.NET Provider -- A Software Application that provides a data access channel between an ADO.NET compliant applications and a backend database management system, using the native protocols of the target DBMS or Driver vendor.
Agent -- A Software Application. May be a Bridge Agent or a Database Agent.
Bridge Agent -- A Software Application. Provides connections to a DBMS-agnostic Data Access Mechanism (e.g., ODBC, JDBC). Enterprise Edition only.
Broker Operating System -- The Operating System on which the Enterprise Edition Request Broker, Database Agents, and/or Bridge Agents will run; where the Enterprise Edition product (license) will be deployed.
Broker Operating System Type -- The Types (Workstation or Server) of Operating System on which the Enterpris Edition product (license) may be deployed.
Data Access Protocol Scope -- Specific data access protocol(s) (ODBC, JDBC, ADO.NET, OLE DB, and/or XMLA) supported by data access driver (Express or Lite Edition) and/or license (Enterprise Edition).
Database Agent -- A Software Application. Provides connections to a specific DBMS (e.g., Oracle 11g, Microsoft SQL Server, MySQL 5.x). Enterprise Edition only.
Database Engine -- Specific version(s) of a Database Management System (DBMS) supported by an ODBC driver, JDBC driver, ADO.NET provider, OLE DB provider, XMLA provider, or License File.
DBMS Family -- Database Management System (DBMS) Family.
Generic Client -- A Software Application. An ADO.NET Provider, JDBC Driver, or ODBC Driver which connects a client application using such Data Access Mechanism to a Request Broker and associated Agents. Enterprise Edition only.
JDBC Driver -- A Software Application. A Software Application that provides a data access channel between a JDBC compliant applications and a backend database management system, using the native protocols of the target DBMS or Driver vendor.
Maximum Concurrent Client Machines — The maximum number of client hosts (physical or virtual, metered by IP address) which may simultaneously open ODBC, JDBC, ADO.NET, OLE DB, and/or XMLA database sessions through a Request Broker and/or Database or Bridge Agent under the given license. Only applicable to Enterprise Edition.
Maximum Database Sessions -- Maximum concurrent database sessions which may be opened under the given license. Opening a new session increments the count; closing an active session decrements the count. For Express or Lite Edition Drivers, this is per licensed host. For Enterprise Edition, this pool is shared by all client connections going through a given Request Broker.
Maximum Logical Processors -- The maximum number of Logical Processors which the operating system reports as present in the machine (physical or virtual) on which the product (license) is deployed, i.e., the Express Edition Driver Host, Lite Edition Driver Host, or Enterprise Edition Request Broker Host.
ODBC Driver -- A Software Application. A Software Application that provides a data access channel between an ODBC compliant applications and a backend database management system, using the native protocols of the target DBMS or Driver vendor.
OLE DB Provider -- A Software Application. A Software Application that provides a data access channel between an OLE DB compliant applications and a backend database management system, using the native protocols of the target DBMS or Driver vendor.
Request Broker or simply Broker -- A Software Application. Receives connection requests from Generic Clients, and apportions these to Agents according to Rules defined by its administrator. Enterprise Edition only.
XMLA Provider -- A Software Application. A Software Application that provides a data access channel between an XMLA compliant applications and a backend database management system, using the HTTP protocol.

Virtuoso Glossary Terms

Client Application Connectivity Protocol Restrictions -- Client application connectivity protocol restriction which specifies the criteria of how a license allows an application to connect to a server.
Client Application Restrictions -- Client application restriction which specifies the criteria of how a license allows an application to connect to a server.
Client Connection Restrictions -- Client connection restriction which specifies the criteria of how a license allows a client to connect to a server.
"Cluster" Module -- Enables Virtuoso Shared-Nothing Cluster functionality. Not required for Virtuoso Replication Clusters .
Clustering -- Indicates whether the additional "Cluster" Module is enabled for the Software Application License.
Column Store -- Indicates whether the additional "Column Store" Module is enabled for the Software Application License.
"Column Store" Module -- Enables Column Store functionality.
Connections -- Client interface portals, formerly known as Database Server Threads . A configurable number are dedicated to handling HTTP-based client requests; the remainder are available for any other data access mechanism (ODBC, JDBC, OLE DB, ADO.NET, XMLA, etc.).
CPU Affinity -- A programming mechanism by which an Application binds to one or more CPU Cores (Logical and/or Physical), irrespective of total available.
CPUs -- The maximum number of Logical Processors which the Software Application will utilize. On Windows and Linux (and soon on Solaris, AIX, and HP-UX), this is managed by CPU Affinity, so the license may be used on machines which report any number of processors, but the software will only utilize the number specified by the license.
- Note: Mac OS X does not support CPU Affinity, so your license must enable utilization of at least as many Logical Processors as are reported present in your Mac.
Database Server Threads -- See Connections .
Operating System -- The Operating Systems for which the Software Application License may be scoped.
Virtuoso Cluster -- A collection of Virtuoso Server Instances configured to operate together, either as a Virtuoso Replication Cluster or a Virtuoso Shared-Nothing Cluster . A Virtuoso Cluster may be housed on a single machine, or distributed over multiple machines, which may themselves be geographically dispersed.
Virtuoso Cluster Node (VCN) -- A Virtuoso Server Quorum that's a member of a Virtuoso Shared-Nothing Cluster . Requires that the "Cluster" Module be licensed.
Virtuoso Host Cluster (VHC) -- A collection of machines, each hosting one or more Virtuoso Server Instances that are members of a Virtuoso Cluster .
Virtuoso Host Cluster Node (VHCN) -- A machine hosting one or more Virtuoso Server Instances that are members of a Virtuoso Cluster .
Virtuoso Replication Cluster -- A collection of Virtuoso Server Instances and/or Virtuoso Shared-Nothing Clusters , each working individually, which are configured into any supported replication topology (e.g., star, chain, bidirectional). Requires that the "Cluster" Module be licensed if the Virtuoso Replication Cluster is comprised in part or in whole of Virtuoso Shared-Nothing Clusters .
Virtuoso Server Instance (VSI) -- One instantiation of the Virtuoso Server executable, minimally comprising an INI file, a DB file, and a TRX file.
Virtuoso Server Quorum (VSQ) -- A collection of one or more mutually-mirroring Virtuoso Server Instances configured to operate as and appear to the world as one Instance, typically comprising a Virtuoso Cluster Node , as part of a Virtuoso Shared-Nothing Cluster . Requires that the "Cluster" Module be licensed.
Virtuoso Shared-Nothing Cluster -- A collection of Virtuoso Cluster Nodes , working in parallel, controlled by a single "Master" Node. Optimal performance typically requires network, if not physical, proximity. Requires that the "Cluster" Module be licensed.
