Difference between SOQL and SOSL

SOQL	SOSL
SOQL is used if we know in which object the data is present.	SOSL is used if we don't know in which object the data is present.
In SOQL we can query data from the single object and as well as multiple objects. In case of multiple objects, the objects should have some relationship between them.	In SOSL we can search data from multiple objects even if there is no relationship among the objects.

Unlike SOQL, which can only query one object at a time and multiple objects only if they are related to each other, SOSL enables you to search text, email, and phone fields for multiple objects simultaneously.
