How to Merge (combine) Data in Stata

When we work on data analysis we first need to merge data or combine data in a single file. This can be done using the merge command in Stata. There are different types of merges i.e. one to one merge, one to many merge, many to many merge, and many to one merge. Then there are different details related to the merging of data i.e. the nogenerate option, keep specific variables or using multiple key variables to merge data.
