denormalization - Automatic denormalizing by query -

i wonder if it's possible create logic automatically creates denormalized table , it's data (and maintains it) specific sql-like query. given system user can maintain data model , data. data stored in "relational" tables, tables used user maintain data. if wants display data on webpage has write query (sql) automatically turn denormalized table , kept up-to-date when updating/deleting relational data. let's got query this: select t1.a, t1.b t1 t1.c = 1 the logic automatically create denormalized table copy of needed data according query. it's view (i wonder if views more performant approach). whenever query (give name) needed business logic replaced simple query on new table. any update in t1 search queries t1 involved , update denormalized data automatically, performance win update rows infected (in example 1 row). that's point i'm not sure if it's achievable in automatic way. example query simple, if there queries joins, aggregation
