Day-3 Exploring Oracle, JavaScript

Today I have gone through the integrity constraints in deeper. then i performed some operations like creating the table with check and i learned the relationship among the table using one-to-one They are used to combine to table in which the one values of the table should match with the exactly with one another in other table using the unique 1 to many is same as one-to-one but we don't use the unique many-to-many we have the relation like making the relation between multiple records in one table are related to multiple records in another table. and some basics of join how we are join the table using the join i learned about the self join in which we can get the table using the same table. outer join and inner join inner join gives the only the matched results but wont return the unmatched records. I am always looking forward of my journey towards my career . That's it for today

Day-3 Exploring Oracle, JavaScript

Today I have gone through the integrity constraints in deeper.
then i performed some operations like creating the table with check and i learned the relationship among the table using

one-to-one They are used to combine to table in which the one values of the table should match with the exactly with one another in other table using the unique
1 to many is same as one-to-one but we don't use the unique
many-to-many we have the relation like making the relation between multiple records in one table are related to multiple records in another table.
and some basics of join how we are join the table using the join i learned about the self join in which we can get the table using the same table. outer join and inner join
inner join gives the only the matched results
but wont return the unmatched records.
I am always looking forward of my journey towards my career .
