OLTP vs. OLAP
Definition of OLTP System
OLTP stands for On-line Transaction Processing and is the kind of information technology which helps in managing different transactions which are carried out in such business-related environments, they keep checks on every data which has been entered and point towards the exact location of data whenever it is required. Other features of this include that it gives image view of all the business related activities going on at the current time. Helps in managing and running of different business activities while the data stored is in the form of operational data. It also allows for backups and recovery which gives it an advantage over others, though this takes more space than necessary. For making the transactions, there is less space required so the system can work on a smaller level in a current state. It deals with simple queries which have lower data, which also have fewer records. Therefore, the speed of OLTP system is fast.
Definition of OLAP System
OLAP stands for On-line Analytical Processing and performs a multi-dimensional analysis which checks data in different business activities and solves complex problems. The primary purpose of this is to resolve these issues, suggest solutions and to take decisions which help in making the system better. It is known as a system which is relatively slow, but that is because it has to analyze a broad range of data which can contain important files. Therefore, the speed is variable depending on the process at hand. There are no proper backups available, but the data can be loaded from different environments which save space and make the system simpler. It has consolidated data which means the information comes from various sources but can be viewed in multi-dimensional views for different business activities but deals with the compound systems instead of taking the easier route. It has longer update times and takes a while to refresh data since it is not available in a proper space.
