| MatrixOne | MatrixOne | The cloud database instance in the product family |
| Unified Account | Unified Account | One shared account for AI Studio / Genesis / MatrixOne; register once for access to all |
| Sub-product Switching | — | Switch among sub-products from the top bar without signing in again |

| Data Mode | Data Mode | UI configuration mode for data engineers (shown as “Data” in navigation) |
| Agent Mode | Agent Mode | Conversation-driven mode for building agents |
| App Mode | App Mode | Delivery mode for packaging an agent as an interactive application |
| MOMO Product Assistant | MOMO | Global product assistant that answers usage questions based on product documentation |

## Data Dimension

| Term | English | Definition |
| --- | --- | --- |
| Catalog | Catalog | Workspace data asset center for raw and processed data, models, operators, and more |
| External Database Catalog | — | Registers only external database metadata; data remains in the source database and queries can be pushed down |
| Knowledge Base | Knowledge Base | Logical wrapper for Catalog data, provided to agents as a data set |
| Data Lineage | Data Lineage | Traces the data path from sources to agents and other destinations |
| Connector | Connector | Channel for data movement: import (external → internal) and export (internal → external) |
| Connector Type | Connector Type | Template that defines “what can be connected” in Data Mode |
| Connector Tool | Connector Tool | Representation of a connector type in Agent Mode |
| Connector Instance | Connector Instance | Ready-to-use connection with credentials configured |
| Data Sharing | Data Sharing | Cross-workspace “publish → subscribe”; the subscriber usually receives a read-only subscription database |

## Capability Dimension

| Term | English | Definition |
| --- | --- | --- |
| Tool | Tool | Smallest capability unit; programmatic and deterministic |
| Operator | Operator | Processing unit in Data Mode, such as parsing, chunking, or embedding; after snapshot import, it can appear as a tool |
| Skill | Skill | Orchestration of tools; a natural-language workbook orchestrated by an LLM and therefore nondeterministic |
| Workflow Template | Workflow Template | Operator DAG orchestration; after snapshot import, it can appear as a skill; versioned, without branches |
| Workflow Instance | Workflow Instance | Runtime form of a skill, bound to knowledge bases and parameters; can have branches |
| Workflow Branch | Workflow Branch | A variation of an instance with small parameter changes for comparing results |
| Agent | Agent | Container for skills, tools, knowledge bases, and prompts |
| AI App | App | Interactive application hosted by the platform with an embedded agent |
| Summary | desc | One-sentence description of a skill's purpose, used for routing and lists |
| Execution Instruction | Instruction | Detailed steps followed when a skill is invoked |
| System Prompt | System Prompt | Prompt at the agent level (do not confuse it with an execution instruction) |

## Mechanisms and Runtime

| Term | English | Definition |
| --- | --- | --- |
| Snapshot Mechanism | Snapshot | Records a version when importing an operator / template, binding to the snapshot instead of tracking live changes |
| Task | Task | Agent execution path: the user provides a goal and the agent works autonomously (the UI consistently uses “Task,” not “Job” or “Ticket,” for this concept) |
| Sandbox | Sandbox | Isolated execution environment for code / tools |
| Compute Resource | Compute Resource | Resource for background jobs, including query resources (SQL) and task resources (non-SQL) |
| MCP | Model Context Protocol | Model Context Protocol; an agent can act as an MCP Server |
| Memoria | Memoria | Memory capability across Sessions |
| Vibe Coding | Vibe Coding | Application-building method that generates an initial draft through conversation and fine-tunes it in the UI |

## Billing

| Term | English | Definition |
| --- | --- | --- |
| Credit | Credit | Unified billing currency of the platform |
| AI Service | AI Service | Billing for system AI capabilities, including conversations, orchestration, knowledge bases, and system operators; underlying models are hidden and pricing is unified |
| Genesis (Billing Item) | Genesis | Billing for externally offered model services, priced by model (input / output / cache, and others) |
| Bring Your Own Model | BYOM | Connect your own model API; the platform charges a fixed service fee independent of model pricing |
| Usage-based Billing | Usage-based | Credit is deducted based on usage of compute, AI services, storage, traffic, Genesis, BYOM, and more |
| Monthly Fixed Billing | Subscription | Dedicated support, enterprise identity authentication, and similar services billed at a fixed monthly rate |

## Terminology Conventions

- Use **Agent** consistently in the UI; internal identifiers may use `agent`.
- Use **Task** consistently; do not interchange “Job” or “Ticket” for the same concept.
- “System Prompt” and “Execution Instruction” serve different purposes and must not be used interchangeably.
- Always replace Nexus / TaaS in older materials with **Genesis**.
