5 Types of operational data store you should know!
Operational data stores come in various types, each designed to serve different purposes and business needs. The choice of ODS type depends on the specific requirements of an organization.
Here are some of the main types of operational data stores (ODS):
- Near-real-time ODS
- Batch ODS
- Analytical ODS
- Data mart
- Data consolidation ODS
Let us understand each of them in detail.
1. Near-real-time ODS
- Near-real-time ODS is similar to real-time ODS but typically involves slightly delayed updates, which can range from a few seconds to a few minutes. This type of ODS is suitable when instant updates are not critical but data still needs to be very current for tactical decision-making.
