## What it is
Ctrip DAL is a database access framework developed by Ctrip's framework team, providing code generation and horizontal scaling (database and table sharding) for Java and C# clients against MySQL and MS SQL Server. It includes a web-based code generator that produces ready-to-use DAO code and configuration, plus client libraries with monitoring, logging, and extensive extension points.

## Use cases
- shard a mysql database across multiple servers in a java application
- generate DAO code automatically from database schema
- standardize database access across multiple teams in a company
- split large tables across databases for horizontal scaling
- access sql server from java or c# with a unified data access layer
- manage database ownership and access conventions organization-wide

## When to choose
- you need database/table sharding with generated DAO code in Java or C#
- your organization wants a unified, centrally managed database access standard
- you use MySQL or MS SQL Server and want zero hand-written data access boilerplate

## When to avoid
- you prefer modern ORM or query-builder approaches like MyBatis, JPA/Hibernate, or jOOQ
- you use databases other than MySQL or MS SQL Server
- you work outside the Java/C# ecosystems
- you want a lightweight library without deploying a code generator service
