An OLTP (Online transaction processing) database is a database that allows for quick transaction processing. It involves inserting, deleting, updating data in the database.
OLTP has many drawbacks like if the system fails, all transactions are going to have problems. Also, since multiple users are allowed to access the data, it makes it prone to hackers.
The solution to the problems associated to the OLTP database is the OLAP (online analytical processing) database.
The OLAP systems allow users to analyze database information from multiple database systems at one time thereby allowing analysis for business decisions.
