Comprehensive Field Types - -**Primitive Types:** -- `string`, `integer`, `number`, `boolean` - -**Temporal Types:** -- `date`, `datetime`, `time`, `year`, `yearmonth`, `duration` - -**Spatial Types:** -- `geopoint`, `geojson` - -**Complex Types:** -- `array`, `list`, `object` - -### 3. Smart Schema Inference - -Automatically infers field types and formats from data using: -- Regex pattern matching with configurable confidence thresholds -- Locale-specific format detection (comma decimals, date formats) -- Complex type recognition (objects, arrays, temporal data) - -### 4. Flexible Field Matching Strategies - -- **exact**: Fields must match exactly in order and count -- **equal**: Same fields in any order -- **subset**: Data must contain all schema fields (extras allowed) -- **superset**: Schema must contain all data fields -- **partial**: At least one field must match - -### 5. Advanced Data Processing - -**Format-Aware Parsing:** -- Handles missing values at schema and field levels -- Supports group/decimal character customization -- Processes currency symbols and whitespace -- Parses complex formats (ISO dates, scientific notation) -

-## Error Handling - -### Comprehensive Error Taxonomy - -**Field Errors:** -- Name mismatches between schema and data -- Type conversion failures -- Missing or extra field violations - -**Cell Errors:** -- Type validation failures with specific conversion details -- Constraint violations (required, unique, enum, pattern, range, length) -- Format parsing errors with problematic values -

PostgreSQL, and MySQL through Kysely query builder integration. + +## Introduction + +:::tip +You can use `loadTable` and `saveTable` from `@dpkit/all` instead of `@dpkit/database` to load and save database tables if the framework can infer the database connection format. +::: + +The Database plugin is a part of the [dpkit](https://github.com/datisthq/dpkit) ecosystem providing these capabilities: + +- `loadDatabaseTable` +- `saveDatabaseTable` +- `inferDatabaseSchema` +- `loadPackageFromDatabase` + +For example: + +```typescript +import { loadDatabaseTable } from "@dpkit/database" + +const table = await loadDatabaseTable({ + path: "sqlite://database.db", + dialect: { table: "users" } +}) +// field types will be automatically inferred from database schema +// or you can provide a Table Schema +``` + +:::tip +The ouput of `loadDatabaseTable` is a Polars LazyDataFrame, allowing you to use all of the power of Polars for data processing. +::: + +## Supported Databases + +The plugin supports three database types: + +- **SQLite** - File-based database (`sqlite://path/to/file.db`) +- **PostgreSQL** - Network database (`postgresql://user:pass@host:port/db`) +- **MySQL** - Network database (`mysql://user:pass@host:port/db`) + +## Connection Formats + +Database connections are specified using standard connection strings: + +```typescript +// SQLite +const sqliteTable = await loadDatabaseTable({ + path: "sqlite://data.db", + dialect: { table: "products" } +}) + +// PostgreSQL +const pgTable = await loadDatabaseTable({ + path: "postgresql://user:password@localhost:5432/mydb", + dialect: { table: "orders" } +}) + +// MySQL +const mysqlTable = await loadDatabaseTable({ + path: "mysql://user:password@localhost:3306/mydb", + dialect: { table: "customers" } +}) +``` + +## Schema Inference + +The database adapter automatically infers Table Schema from database table definitions: + +```typescript +import { inferDatabaseSchema } from "@dpkit/database" + +const schema = await inferDatabaseSchema({ + path: "sqlite://shop.db", + dialect: { table: "products" } +}) +// Returns a Table Schema with field types matching database columns +``` + +## Package Loading + +Load entire Data Packages from databases: + +```typescript +import { loadPackageFromDatabase } from "@dpkit/database" + +const package = await loadPackageFromDatabase("sqlite://catalog.db") +// Loads all tables as package resources +``` + +## Database Adapters + +The plugin uses database-specific adapters built on Kysely: + +- **BaseAdapter** - Common functionality for all databases +- **SqliteAdapter** - SQLite-specific operations using better-sqlite3 +- **PostgreSQLAdapter** - PostgreSQL operations using pg driver +- **MySQLAdapter** - MySQL operations using mysql2 driver + +Each adapter handles: +- Type normalization between database and Table Schema types +- Connection management with LRU caching +- Database-specific SQL dialect handling
