Für was steht OLTP?
Online-Transaction-Processing (OLTP), Online-Transaktionsverarbeitung, auch Echtzeit-Transaktionsverarbeitung, bezeichnet ein Benutzungsparadigma von Datenbanksystemen und Geschäftsanwendungen, bei dem die Verarbeitung von Transaktionen direkt und prompt, also ohne nennenswerte Zeitverzögerung, stattfindet.

Which is better online transaction processing ( OLTP ) or OLAP?
OLTP enables the real-time execution of large numbers of transactions by large numbers of people, whereas online analytical processing (OLAP) usually involves querying these transactions (also referred to as records) in a database for analytical purposes.
How is the response time of OLTP short?

Why is OLTP difficult for business to query?
The increased normalization coupled with terse naming conventions makes OLTP systems difficult for business users to query, without the help of a DBA or data developer. Storing the history of transactions indefinitely and storing too much data in any one table can lead to slow query performance, depending on the number of transactions stored.
