## What it is
WCDB is a cross-platform mobile database framework developed by WeChat, built on SQLite and SQLCipher. It provides ORM and a native query language (WINQ) across C++, Java, Kotlin, Swift, and Objective-C.

## Use cases
- store structured data locally on iOS or Android
- encrypt a local SQLite database with SQLCipher
- map objects to database tables without writing SQL strings
- share one database layer across mobile and desktop platforms
- perform CRUD operations from Swift or Kotlin with type-safe queries

## When to choose
- you need an encrypted, high-performance local database on mobile
- you want ORM support across multiple languages in one framework
- you are building a WeChat-scale app needing battle-tested storage

## When to avoid
- you need a server-side or web-only database
- you prefer lightweight direct SQLite access without an ORM layer
- you need a database other than SQLite

## Facets
- artifact type: library
- maturity: active
- function: database, orm, database-driver, cryptography
- domain: databases, mobile-development, cross-platform, security
- platform: windows, cpp, jvm
- tags: sqlite, sqlcipher, wechat, mobile-database, winq, objective-c, kotlin, openharmony, android, ios, macos, linux, swift
