Minimalist framework to collect and handle data in a Digital Twin project

/**
 * @fileoverview Database abstraction layer for digital twin data persistence
 *
 * This module defines the abstract DatabaseAdapter interface that provides
 * unified database operations across different database backends (SQLite, PostgreSQL).
 * Implementations handle component data storage, metadata management, and querying.
 */
/**
 * Abstract database adapter providing unified data operations for all components.
 *
 * DatabaseAdapter defines the contract for database operations used throughout the
 * digital twin system. Implementations provide concrete database access using specific
 * backends (SQLite, PostgreSQL) while maintaining a consistent API.
 *
 * The adapter handles:
 * - Table creation and schema migration for components
 * - CRUD operations for collected data and assets
 * - Time-based and count-based queries for harvesters
 * - Custom table operations for CustomTableManager components
 *
 * @abstract
 * @class DatabaseAdapter
 *
 * @example
 * ```typescript
 * // Using KnexDatabaseAdapter (concrete implementation)
 * const database = KnexDatabaseAdapter.forSQLite({
 *   filename: './data/digitaltwin.db'
 * }, storage)
 *
 * // Save collector data
 * await database.save({
 *   name: 'weather-collector',
 *   type: 'application/json',
 *   url: await storage.save(buffer, 'weather-collector'),
 *   date: new Date()
 * })
 *
 * // Query latest data
 * const latest = await database.getLatestByName('weather-collector')
 * const data = await latest?.data()
 * ```
