# Databases Tool - Full Documentation
## Overview
Database operations: create, get, query, create_page, update_page, delete_page, create_data_source, update_data_source, update_database.
## Architecture
- **Database** = container holding one or more data sources
- **Data Source** = has schema (properties) and rows (pages)
## Workflow
1. create → Creates database + initial data source
2. get → Retrieves data_source_id
3. query/create_page/update_page → Uses data_source_id (auto-fetched)
## Actions
### create
```json
{"action": "create", "parent_id": "xxx", "title": "Tasks", "properties": {"Status": {"select": {"options": [{"name": "Todo"}, {"name": "Done"}]}}}}
```
### get
```json
{"action": "get", "database_id": "xxx"}
```
### query
```json
{"action": "query", "database_id": "xxx", "filters": {"property": "Status", "select": {"equals": "Done"}}}
```
### create_page
```json
{"action": "create_page", "database_id": "xxx", "pages": [{"properties": {"Name": "Task 1", "Status": "Todo"}}]}
```
### update_page
```json
{"action": "update_page", "page_id": "yyy", "page_properties": {"Status": "Done"}}
```
### delete_page
```json
{"action": "delete_page", "page_ids": ["yyy", "zzz"]}
```
