DB Module (src/DB)

# DB Module (`src/DB`)

This module provides the core database interaction layer, abstracting the underlying SQLite database.

## Core Components

### `DB.js`

- **Purpose:** Provides a high-level abstraction for database connections and operations. It likely manages connection pooling and simplifies common database tasks.
- **Key Features:** (To be determined by analyzing the file)
- **Dependencies:** `SQLite.js`, `Statement.js`

### `SQLite.js`

- **Purpose:** Wraps the `sqlite3` library to provide a more promise-based and potentially enhanced interface for interacting directly with SQLite.
- **Key Features:** (To be determined by analyzing the file)
- **Dependencies:** `sqlite3`, `Statement.js`

### `Statement.js`

- **Purpose:** Represents a prepared SQL statement, likely offering methods for binding parameters and executing the statement efficiently.
- **Key Features:** (To be determined by analyzing the file)
- **Dependencies:** `sqlite3`

## Usage

(To be determined by analyzing the code and tests)

## Dependencies

- `sqlite3`: The underlying Node.js driver for SQLite.
- `async-sema`: Likely used for managing concurrency or locking around database operations.
- `dataloader`: Potentially used for batching and caching database reads.
- `debug`: Used for logging debug information.
- `lodash`: Utility library, potentially used for various data manipulations.
