@sladiri as I said before in this forum, GraphQL is a query language that assumes a "virtual database" architecture. This kind of architecture has been tried several times over the last 20 years (companies like MetaMatrix, Composite Software...). I was the co-author of the Object Data Service specification which is the ancertor to GraphQL (~2005). The most recent attempt was ql.io by Subbu Allamaruju (eBay, now Expedia) and it failed. Subbu is one of the most respected engineers in our Industry. In some very constrained cases, these approaches have some value, in the general case I have only one thing to say, good luck.
