OLTP is carried in a client-server system. Online transaction process concerns about concurrency and atomicity. Concurrency controls guarantee that two users accessing the same data in the database system will not be able to change that data or the user has to wait until the other user has finished processing, before changing that piece of data.
Since the early 1990s, the operational database software market has been largely taken over by SQL engines. In 2014, the operational DBMS market (formerly OLTP) was evolving dramatically, with new, innovative entrants and incumbents supporting the growing use of unstructured data and NoSQL DBMS engines, as well as XML databases and NewSQL databases.
The term OLAP was created as a slight modification of the traditional database term online transaction processing (OLTP). [2] OLAP is part of the broader category of business intelligence, which also encompasses relational databases, report writing and data mining. [3]
Good data placement: The database should be designed to access patterns of data from many simultaneous users. Short transactions: Short transactions enables quick processing. This avoids concurrency and paces the systems. Real-time backup: Backup should be scheduled between low times of activity to prevent lag of the server.
Oracle Database (commonly referred to as Oracle DBMS, Oracle Autonomous Database, or simply as Oracle) is a proprietary multi-model [4] database management system produced and marketed by Oracle Corporation. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW
In September 2019, Greenplum Database Version 6 was released. Version 6 is based on PostgreSQL version 9.4 and features massive gains in [23] OLTP performance. Greenplum 6 was reviewed in the media by several sources and mentioned for its Postgres open source alignment [24] and for its OLTP performance [25]

NewSQL is a class of relational database management systems that seek to provide the scalability of NoSQL systems for online transaction processing (OLTP) workloads while maintaining the ACID guarantees of a traditional database system.
