Yes, relational algebra can be considered a branch of abstract algebra, as it involves a set of operations on relations, which can be viewed through the lens of mathematical structures. Relational algebra provides a formal framework for querying and manipulating data in databases, utilizing concepts such as sets and operations like union, intersection, and difference. While it specifically focuses on data manipulation, its foundations are rooted in the principles of abstract algebra.

This is a big question. I you enter 'relational algebra' in a search engine, you will find many sites which go over this. Wikipedia usually takes a very high level abstract approach. The link below seems fairly easy to understand.
