Biggest problem : Entity and Type declaration

Let me know if you have proper solutions for this.

While creating software we have to declare entity or type multiple times.

I am using GraphQL+Sequelize+PostgreSQL. Let me show some code.

I have to declare Types in GraphQL schema

then I have to define almost same thing in Sequelize too

and at last, almost same thing, I have to define in DB level too

Please let me know if you have better way to create software. Why cannot we have a Universal Representation in JSON.

and this remind me, this.
