The Future of Data Warehouses in the Big Data Era

The data warehouse market has indeed begun to change and evolve with the advent of big data. In the past, it was simply not economical for companies to store the massive amount of data from a large number of systems of record. The lack of cost-effective and practical distributed computing architectures meant that a data warehouse was designed so it could be optimized to operate on a single unified system.

Therefore, data warehouses were purpose-built to address a single topic. In addition, the warehouse had to be carefully vetted so that data was precisely defined and managed. This approach has made data warehouses accurate and useful for the business to query these data sources.

This same level of control and precision has made it difficult to provide the business with an environment that can leverage much more dynamic big data sources. The data warehouse will evolve slowly.

Data warehouses and data marts will continue to be optimized for business analysis. However, a new generation of offerings will combine historical and highly structured data stores with different stages of big data stores.

First, big data stores will provide the capability to analyze huge volumes of data in near real time. Second, a big data store will take the results of an analysis and provide a mechanism to match the metadata of the big data analysis to the requirements of the data warehouse.
