Who first gave the concept of periodicity?
The concept of periodicity was first introduced by Dmitri Mendeleev when he created the periodic table in 1869, which arranged the elements based on their atomic mass and properties. Mendeleev's table allowed for the prediction of the properties of undiscovered elements and is considered a landmark achievement in the field of chemistry.

Explain referential integrity constraints in terms of relational algebra?
Referential integrity is a database concept that ensures that relationships between tables remain consistent. When one table has a foreign key to another table, the concept of referential integrity states that you may not add a record to the table that contains the foreign key unless there is a corresponding record in the linked table. It also includes the techniques known as cascading update and cascading delete, which ensure that changes made to the linked table are reflected in the primary table. By Mehari Tewelde
