文章标签 实践 sqlcoder

本文主要是介绍sqlcoder实践，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

背景

  • Defog

  • llama-3

意义

翻译自然语言到sql，类似脑机接口，大模型重要应用领域

  • sql是数据库查询标准;关系数据库，工具(datax,sqoop，logstash,hive)，非关系数据库（MongoDB，图数据库）等都支持sql查询

  • BI，数字化运营，商业分析，大数据分析

  • 智能问数

  • 智能问答

  • 没有大模型前智能问答方案 ：

  • 开源项目 QABasedOnMedicaKnowledgeGraph

  • https://gitcode.com/liuhuanyong/QASystemOnMedicalKG/overview?utm_source=csdn_github_accelerator&isLogin=1

待完善

  • 可靠性

  • 复杂，不规范的数据库表

  • 信息安全
