Transactional data is collected for every event that happens in a business, from the purchase of an item to the modifying of an order. It describes events, while operational data is the data that supports all operations, including the transactions happening within the system. Transactional data has a time dimension to it, such as when and at what time a purchase occurred. Both operational and transactional data are important sources of information in a business.
Businesses usually have solutions in place to deliver up the insights they need to get from data, from relational database systems and data warehouses to data lakes and data marts. They need these insights from data to help them to rise above the competition. It should be possible for them to find the right data at the right time to support many different use cases, from simple reporting to complex analysis.
The data warehouse and the operational data store
A data warehouse offers a way to manage historical data, deliver batch updates, support regular reporting cycles, and serve as a single source of truth. The data goes through various sources through ETL (extract, transform, load) to the data warehouse. The data warehouse is good at handling planned workloads and offers access to a single source of historical data. As it provides a static source of data, it has limited adaptability and agility. Various evolving trends, like self-service analytics and the explosion of apps, have amplified the limitations.
An operational data store offers more data flexibility. It integrates data coming from different systems of record, making it possible to access this data in real-time or near real-time for comprehensive reporting. It supports the operating systems and is made up of snapshots from operations, holding no historical data.
The data in an ODS is subject-oriented as it is organized around subjects like customers, sales and products. Data information in the ODS is usually structured like the source systems and during integration, cleaning, resolving redundancies and applying business rules take place to ensure the integrity of the information. An ODS can act as a source for a data warehouse.
The ODS offers the most current and fine-grained data for querying while not burdening transactional systems. Businesses can perform simple queries on small sets of data, such as finding out the status of an order.
Transactional data exists in large volumes in businesses and is generated regularly. It is commonly used in operational applications like ERP systems and HR systems. Every event in a business creates transactional data, such as selling products to customers, hiring employees or buying products from suppliers. Transactional data has a time aspect to it and a numerical value. Some examples of transactional data are invoices, orders, payments, delivery records, and payments.
If a customer purchases a number of products at different times, a transaction record is created for each sale, but the data about the customer remains the same. The customer record does not have to be modified for the new transaction. Transaction data is, therefore, typically more volatile as it is created and changed frequently.
Digital transformation requires new solutions
The Internet of things, adopting blockchain technology, artificial intelligence, machine learning and new business models are all driving the need for new solutions when it comes to performing real-time analysis to drive action without slowing down performance.
Data latency happens due to the time it takes to move and transform data between storage solutions. Appropriate data design has to address this and improve load performance.
The traditional ODS is often based on a relational database and handling large amounts of data is a problem. The low latency required by digital applications is not possible with a traditional ODS. If too many users access data currently, it affects performance. The refresh rate of a traditional ODS is also not acceptable for digital applications because they need real-time data.
When many digital applications call APIs directly to access multiple systems of record, conventional architecture does not suffice anymore. The paradigm shift has led to the creation of next-generation operational data stores that address the limitations.
A next-generation ODS
A next-generation ODS offers a great improvement over the traditional ODS in terms of factors like scalability, throughput and availability.
High speed: Distributed in-memory computing offers the speed to power digital applications. Performance is not affected, even when there is a high concurrency of users.
Autonomous scaling: Unplanned drops or peaks in volume are not a problem with a next-generation ODS. It can scale effectively to maintain customer experience during peaks in volume and prevent over-provisioning of resources on-premise when volume drops.
High availability: When the API layer is decoupled from the systems of record, a business can continue to function even if one system is down. For example, it would be possible to check the credit status of a customer even if the credit authorization system was down.
Accurate predictive modeling: Analyzing real-time data and enriching it with historical data enables robust predictive modeling.
Hybrid deployment support: Global organizations may have data centers in remote regions while others have data in the cloud and on-premise. A next-generation ODS supports hybrid deployment.
Flexibility is going to be a major key for businesses to consistently meet changing needs and remain competitive in the future. New technology is changing the game and businesses must understand their objectives when it comes to using data effectively. They must consider only moving data to locations that are best for performance and then optimize the process to meet customer needs.

Businesses need to use the right type of data at the right time to inform their decision-making. They need to modernize their architecture if they are embracing digital transformation. They may choose to augment their existing systems or replace them. A next-generation ODS offers them the benefit of high performance, more speed, scalability and high availability. By using an ODS like this, it is possible to query the most current and fine-grained data without affecting transactional systems.
