The goal of Spring Data repository abstraction is to significantly reduce the amount of boilerplate code required to implement data access layers for various persistence stores.
Spring Data Repositories is a useful tool for providing pre-built functionality & other convenient features for querying, altering, & accessing your data from a connected data base or other data storage system.
What you are referring to with @Repository is the spring annotation. This is usually a class-level annotation when defining your individual repository classes.
It is only "required" if you intend on using these types of repository classes. While there are other alternative means for querying your data, spring repositories are quite handy.
