DyDaQ framework connects GraphQL service layer with database efficiently

GraphQL Dynamic Data Query - DyDaQ

DyDaQ is a framework which connects GraphQL service layer (resolvers) with database efficiently, it generates highly optimal SQL queries which suits better for GraphQL and makes GraphQL to Database calls lean / high performance.

Example GraphQL Query:

query{ 
    getHospitalDetails(){
      Name
      Address
      City
      }
    }

😟 Traditional JPA Query to DB -> Select * from HospitalDetailsTable;

😊 GraphQl Optimized DyDaQ -> Select Name, Address, City from HospitalDetailsTable;

Features

1. Generates DB SQL queries on the fly dynamically
2. SQL are lean and optimized for GraphQL
3. Support simple queries, complex joins and aggregations
4. Supports Native queries - write your own SQL
5. Plugin added to generate DTO/POJO (can also use Intellij/Eclipse JPA plugin to generate it)
