Discover how businesses are leveraging real-time data warehouses to gain actionable insights, make informed decisions, and drive growth.
Gone are the days when organizations had to rely on stale, outdated data for their strategic planning and operational processes. Now, real-time data warehouses process and analyze data as it is generated, helping overcome the limitations of their traditional counterparts. The impact of real-time data warehousing is far-reaching. From eCommerce businesses to healthcare providers, real-time data warehouse examples and applications span various sectors.
The significance of real-time data warehousing becomes even more evident when we consider the sheer volume of data being generated today. The global data sphere is projected to reach a staggering 180 zettabytes by 2025 .
With these numbers, it’s no wonder every company is looking for solutions like real-time data warehousing for managing their data efficiently. However, getting the concept of a real-time data warehouse, particularly when compared with a traditional data warehouse, can be quite intimidating, even for the best of us.
In this guide, with the help of a range of examples and real-life applications, we will explore how real-time data warehousing can help organizations across different sectors overcome the data overload challenge.
A Real-Time Data Warehouse (RTDW) is a modern tool for data processing that provides immediate access to the most recent data. RTDWs use real-time data pipelines to transport and collate data from multiple data sources to one central hub, eliminating the need for batch processing or outdated information.
Despite similarities with traditional data warehouses, RTDWs are capable of faster data ingestion and processing speeds. They can detect and rectify errors instantly before storing the data, providing consistent data for an effective decision-making process.
Traditional data warehouses act as storage centers for accumulating an organization’s historical data from diverse sources. They combine this varied data into a unified view and provide comprehensive insights into the past activities of the organization. However, these insights are often outdated by the time they are put to use, as the data could be days, weeks, or even months old.
On the other hand, real-time data warehousing brings a significant enhancement to this model by continuously updating the data they house. This dynamic process provides a current snapshot of the organization’s activities at any given time, enabling immediate analysis and action.
Let’s look at some of the major differences between the two.
RTDWs are more complex and costly to implement and maintain than traditional data warehouses. This is because they require more advanced technology and infrastructure to handle real-time data processing.
Traditional data warehouses predominantly assist in long-term strategic planning. However, the real-time data updates in RTDWs make them suitable for both immediate, tactical decisions and long-term strategic planning.
Because of fresher data availability, RTDWs make it easier to connect data-driven insights with real business results and provide immediate feedback.
RTDWs demand constant data updates, a process that can be carried out without causing downtime in the data warehouse operations. Typically, traditional warehouses don't need this feature but it becomes crucial when dealing with data updates happening every week.
While the lines between traditional data warehouses and real-time data warehouses are now blurred due to some data warehouses adopting streaming methods to load data, traditionally, the former updated their data in batches on a daily, weekly, or monthly schedule. As a result, the data some of these data warehouses hold may not reflect the most recent state of the business. In contrast, real-time data warehouses update their data almost immediately as new data arrives.
Let's take a closer look at different types of data warehouses and explore how they integrate real-time capabilities.
An Enterprise Data Warehouse (EDW) is a centralized repository that stores and manages large volumes of structured and sometimes unstructured data from various sources within an organization. It serves as a comprehensive and unified data source for business intelligence, analytics, and reporting purposes. The EDW consolidates data from multiple operational systems and transforms it into a consistent and standardized format.
The EDW is designed to handle and scale with large volumes of data. As the organization's data grows over time, the EDW can accommodate the increasing storage requirements and processing capabilities. It also acts as a hub for integrating data from diverse sources across the organization. It gathers information from operational systems, data warehouses, external sources, cloud-based platforms, and more.
An Operational Data Store (ODS) is designed to support operational processes and provide real-time or near-real-time access to current and frequently changing data. The primary purpose of an ODS is to facilitate operational reporting, data integration, and data consistency across different systems.
ODS collects data from various sources, like transactional databases and external feeds, and consolidates it in a more user-friendly and business-oriented format. It typically stores detailed and granular data that reflects the most current state of the operational environment.
A Data Mart is a specialized version of a data warehouse that is designed to meet the specific analytical and reporting needs of a particular business unit, like sales, marketing, finance, or human resources.
Data Marts provide a more targeted and simplified view of data. It contains a subset of data that is relevant to the specific business area, organized in a way that facilitates easy access and analysis.
Data Marts are created by extracting, transforming, and loading (ETL) data from the data warehouse or other data sources and structuring it to support analytical needs. They can include pre-calculated metrics, aggregated data, and specific dimensions or attributes that are relevant to the subject area.
The use of RTDWs is now common across many sectors. The rapid access to information they provide significantly improves the operations of many businesses, from online retail to healthcare.
Let’s take a look at some major sectors that benefit from these warehouses for getting up-to-the-minute data.
