More About Database

We continued learning about the DBMS this week. Started with the use of Joins in DBMS.
Then, learnt about the aggregate functions lke max(),min(),sum(),avg() etc.
Learned about Sub queries and covers problem on that concept.
Then, I practised all the queries by making a database with some tables in it and performed operations on it like inserting a new record ,updating an existing record and retrieving the records from the table and then also some complex queries on it using concept of foreign key and primary key i.e. by establishing a relation between more than one table using foreign key.
