# Administer InfluxDB 3 Core

The following articles provide information about managing your InfluxDB 3 Core resources:

### [Identify InfluxDB 3 Core version](/influxdb3/core/admin/identify-version/)

Learn how to identify your InfluxDB 3 Core version using command-line tools, HTTP endpoints, and other methods.

### [Manage databases](/influxdb3/core/admin/databases/)

An InfluxDB 3 Core database is a named location where time series data is stored. Each database can contain multiple tables.

### [Manage tables](/influxdb3/core/admin/tables/)

Tables in InfluxDB 3 Core are synonymous with measurements and contain time series data. Each table has a defined schema with tag and field columns.

### [Manage tokens](/influxdb3/core/admin/tokens/)

Manage tokens to authenticate and authorize access to server actions, resources, and data in an InfluxDB 3 Core instance.

### [Manage the Last Value Cache](/influxdb3/core/admin/last-value-cache/)

The InfluxDB 3 Core Last Value Cache (LVC) lets you cache the most recent values for specific fields in a table, improving the performance of queries that return the most recent value of a field for specific time series or the last N values of a field.

### [Manage the Distinct Value Cache](/influxdb3/core/admin/distinct-value-cache/)

The InfluxDB 3 Core Distinct Value Cache (DVC) lets you cache distinct values of one or more columns in a table, improving the performance of queries that return distinct tag and field values.

### [Query system data](/influxdb3/core/admin/query-system-data/)

Query system tables to see data related to the server, queries, and tables in an InfluxDB 3 Core instance. Use the HTTP SQL query API to retrieve information about your database server and table schemas.

### [Back up and restore data](/influxdb3/core/admin/backup-restore/)

Back up and restore your InfluxDB 3 Core instance by copying object storage files in the recommended order.

### [Performance tuning](/influxdb3/core/admin/performance-tuning/)

Optimize InfluxDB 3 Core performance by tuning thread allocation, memory settings, and other configuration options for your specific workload.

### [Security](/influxdb3/core/admin/security/)

Tune InfluxDB 3 Core security for local requirements.

### [Upgrade InfluxDB 3 Core](/influxdb3/core/admin/upgrade/)

Learn how to upgrade your InfluxDB 3 Core instance to the latest version.

### [Upgrade to InfluxDB 3 Enterprise](/influxdb3/core/admin/upgrade-to-enterprise/)

Upgrade from InfluxDB 3 Core to InfluxDB 3 Enterprise. Your existing data and plugins are compatible–no data migration is required.

### [Use the InfluxDB 3 MCP server](/influxdb3/core/admin/mcp-server/)

Use the **InfluxDB Model Context Protocol (MCP) server** to interact with and manage InfluxDB 3 Core using natural language with LLM agents to query and analyze data, manage databases and more. Query InfluxDB 3 Core documentation from your IDE using the InfluxDB documentation Model Context Protocol (MCP) server.
