Glossary
| ::= | In descriptions of the PQL language, this symbol is shorthand for "is equivalent to" or "can be made of." For example, the phrase assignment ::= path = expression | path = tree_literal means that an assignment can be made of a path, and the path can be an expression or a tree literal. |
| absolute path | The definition of a node by the branches to it, starting from the root of the tree. For example, the absolute path of an interface in the sample database is /network/device/interface. |
| Active Directory | A Microsoft directory service that uses standardized protocols to provide network services such as login authentication, Lightweight Directory Access Protocol LDAP, DNS-based naming, and organization of other network information including computers, user accounts, groups, etc. |
| anchor-point node | The node closest to the root in the clause of a PQL statement. |
| application | A program or plugin that extends GoToAssist's capabilities, such as the GoToAssist Alerts and GoToAssist Inventory. |

| API | The GoToAssist API enables applications to be incorporated directly into GoToAssist, dramatically extending its value. After you load an application, it uses information in the Search Index to add specific functionality. Some applications are developed here at GoToAssist (such as the Network Map), and others are created by independent third parties that are part of our growing community. |
| argument | A value that is passed to a function, such as X in child(X). In PQL, argument is synonymous with parameter. |

| CIDR | Classless Inter-Domain Routing, a notation syntax to indicate IP address ranges and routing packets, implemented in 1993 to slow the growth of routing tables and avoid the rapid exhaustion of IPv4 address across the Internet. CIDR notation specifies IP addresses and their associated routing prefixes, and is utilized by the GoToAssist Crawler to specify IP address ranges to monitor, such as 10.1.6.0/24 to indicate 10.1.6.0 through 10.1.6.255. |
| conditional tree assignment | An element of GoToAssist's PQL language that represents a tree_assignment by defining it with conditions, such as interface[name='eth0']. |
| conditional tree literal | An element of GoToAssist's PQL language that represents a tree_literal by defining it with conditions, such as interface[name='eth0']. A conditional_tree_literal is one or more conditional_tree_assignments. |

| MSI | Microsoft Installer, a software component used to install, maintain, and remove software programs on Windows systems. Commonly called MSI files because of their default file extensions, MSI features include rollback and versioning based on a consistent internal database for reliable operation. See also GPO. |
| parameter | A value that is passed to a function, such as X in child(X). In PQL, parameter is synonymous with argument. |
| path | The location of the anchor-point node in a tree, such as a, a/b, a/b/c, and so on. But not a/, because a trailing slash is meaningless in PQL. |

| restriction | The WHERE clause; the part of a PQL statement that further specifies the node defined in the FROM clause. |
| search index | The GoToAssist Search Index is the repository that stores the information that the GoToAssist Crawler gathers about your network and IT assets. You can query the complex IT information stored in the Search Index, and get results in rich table and chart formats, as well as the familiar simple text hit lists that other search engines provide. |
| select column | An expression of GoToAssist's PQL language that indicates which data to select. |
| select column list | An element of GoToAssist's PQL language that represents an expression that indicates which data to select, and returns zero or more columns of data. For example, if you use *, as in SELECT * FROM /network/device, then all trees and all sub-trees from the /network/device anchor-point are returned in the query results. |
| simple path | An element of GoToAssist's PQL language that represents one way to represent the anchor-point node. A simple_path is always an absolute path, starting with a slash to represent the root node, and using slashes to separate each subsequent node, if there are any. An example of a simple_path that limits the query to the contents of device nodes would be: /network/device. |

| TCP/IP | Transmission Control Protocol/Internet Protocol, also known as the Internet Protocol Suite, a set of protocol standards for communication on the Internet and between networks. Consisting of four abstraction layers – the Link Layer, the Internet Layer, the Transport Layer, and the Application Layer – TCP/IP defines the scope of protocols in each layer, which addresses problems relevant to that layer. |
| tree | Tree_diagram1 A data structure of nodes attached in parent-child relationships, that represent the hierarchical and relational structure of the data. Each node is attached to only one parent, but can have one or more child nodes directly beneath. The one exception is the root at the very top of the tree, which has no parent. Because the root is at the top, it is sometimes called an inverted tree structure. The connection between any two nodes is a branch. The nodes at the end of each branch are leaves or leaf nodes. Only leaf nodes contain values. The elements of a tree include tree_literal, conditional_tree_literal, tree_assignment, and conditional_tree_assignment. |
| tree_assignment | An element of GoToAssist's PQL language that represents an identifier as either an expression or a tree_literal. |
| tree_literal | An element of GoToAssist's PQL language that represents a tree by defining each branch. For example, a path such as /network/device is a tree_literal of three branches: root, network, and device. |
| tree-structured database | The part of the search index where data is stored in structured format, and can be probed by using queries in GoToAssist's PQL language. |
| unattended support | When you use the GoToAssist Remote Support application, unattended support is available for customers to allow you to access their PC when they are away from the computer. |

| VNC | Virtual Network Computing, a platform-independent graphical desktop sharing method that provides remote control and screen sharing using the RFB protocol. |
| VPN | Virtual Private Networking, a computer network that uses public networks such as the Internet to provide secure connections between computers or networks.

| web account | Your GoToAssist Web Account is the face of GoToAssist, where you can retrieve the information stored in the Search Index. You can get your IT information by typing in queries or using searches that are shared by others in the GoToAssist community, which returns the simple text hit lists that we're all familiar with. Keep your finger on the pulse of IT via the customizable GoToAssist Dashboard page by running queries that return rich data reports in table and chart formats. |
