Home > Query Language > Basic Concepts
In contrary to other systems on the market, OOMEGA's query language is neither defined via an object-oriented API nor via a string-typed language: it's just a metamodel. There's also a concrete syntax available which perfectly integrates with Java.
We start with a simple example: Let's find all married persons whose last name contains "Mer".
Query(
from(Person.CID),
where(
and(
like(P(Person.P.lastname), "*Mer*"),
exists(P(Person.P.spouse))
)
)
);
