32 cards. Read the term and the definition here. The deck at the top of this page is optional.

sys_db_object

The table that stores metadata for every table in the platform, including its parent table, label, and extension model. Each table record defines inheritance for dictionary fields.

GlideRecord

Server-side JavaScript API for querying and manipulating table records. Supports addQuery, addEncodedQuery, query, next, get, insert, update, and deleteRecord operations against any accessible table.

GlideAggregate

Extends GlideRecord to perform aggregate queries such as COUNT, SUM, AVG, MIN, and MAX, with groupBy support. Used to avoid loading large result sets into memory.

sys_id

A 32-character globally unique identifier that is the primary key of every record. Records are uniquely addressed by combining the table name with the sys_id value.

ACL evaluation

Access control lists check operation-level (read, write, create, delete) and field-level rules. A user must satisfy at least one matching ACL, and all conditions within that ACL must pass.

Update Set

A container that captures configuration changes such as business rules, UI policies, and workflows for transport between instances. It does not capture table data records.

Predictive Intelligence

Platform machine-learning framework offering classification, regression, and similarity solutions trained on table data to predict field values or surface similar records.

Now Assist

Suite of generative AI skills powered by large language models, invoked from flows, Virtual Agent, and workspace actions to summarize, draft, and recommend content.

UI policy

Client-side rule that makes fields mandatory, read-only, or visible based on form conditions. Runs in the browser and can be bypassed by direct API or import operations.

Data policy

Server-enforced rule that sets fields mandatory or read-only across the UI, imports, and API calls. Unlike UI policies, it cannot be bypassed by non-UI data entry.

Business rule timing

Before rules modify the current record prior to database write; after rules act post-write; async rules run queued; display rules run before form render and replace UI policies.

Client script types

onLoad runs when a form loads, onChange fires when a field changes, onSubmit runs before submit, and onCellEdit fires in list editing. All execute in the browser.

Transform map

Configuration that maps staging table columns to a target table during import. Includes field mappings plus onStart, onBefore, onAfter, and onComplete transform scripts.

Coalesce field

A transform map option that matches existing target records on a unique field. If a match exists the import updates the record instead of inserting a duplicate.

Flow Designer trigger

The event that starts a flow: record created or updated, a schedule, a form submission, or an inbound call. Triggers define the initial data available to actions.

Scoped application

An application with a private namespace and API surface. It cannot modify global artifacts without cross-scope privileges, which improves upgrade safety and isolation.

Instance clone

A process that copies data and configuration from a source instance to a target sub-production instance, preserving target-specific settings such as instance name and email configuration.

System property

An instance-wide configuration value stored in sys_properties and read via gs.getProperty. Values are cached and require a cache flush to reflect changes immediately.

Incident to problem flow

Incidents record disruptions; problems investigate root cause; changes implement the fix; knowledge articles document the resolution for future reuse. Each stage links to related records.

MID Server

A Java agent installed inside a customer network that executes Discovery, Service Mapping, and integration commands, then reports results back to the ServiceNow instance.

Service Mapping

ITOM capability that builds application service maps by tracing entry points and dependencies, populating the CMDB with application services and their underlying CIs.

Event Management

ITOM module that ingests alerts from monitoring tools, applies alert rules and correlation, and can automatically create incidents for significant events.

CSM case table

The customer service case table stores customer issues with links to account, contact, and product records. It extends platform case management with SLA and omni-channel support.

HR case

The hr_case table manages employee requests through centers of excellence, with hr_task subtasks, document templates, and journey designer for onboarding and lifecycle events.

IntegrationHub spoke

A prebuilt connector package containing actions for a specific third-party system. Spokes are used inside Flow Designer to call external APIs without custom scripting.

REST Message

A configuration record defining an outbound REST endpoint, HTTP method, headers, and authentication. Used with REST Message functions to call external services.

Similarity solution

A Predictive Intelligence solution type that finds records similar to a given record based on trained text fields, commonly used for case or incident recommendation.

Virtual Agent topic

A conversational flow defining prompts, branching, and actions. Topics are matched by NLU intents and utterances or by LLM-based topic discovery.

Edge Encryption

A platform capability that encrypts sensitive field data before it leaves the customer network, so the ServiceNow instance stores only ciphertext for protected fields.

CMDB Health Dashboard

A set of scores measuring CI completeness, correctness, and compliance against rules, helping administrators find and remediate poor-quality configuration item data.

Identification and Reconciliation Engine

The CMDB component that applies identification rules to detect duplicate CIs and reconciliation rules to merge or update attributes when multiple data sources report the same CI.

Transaction log

The syslog_transaction table records request timing and SQL details. It is used with the slow query log to diagnose performance problems and missing indexes.
