New TDWI Research Report Explores Drivers, Challenges, and Opportunities for Unified Data Warehouses and Data Lakes

Report examines the convergence of the data warehouse and data lake and how organizations are using these environments together.

SEATTLE, WA, June 9, 2021—TDWI Research has released its newest Best Practices Report: Building the Unified Data Warehouse and Data Lake. This original, survey-based report explains the modernization and evolution of data warehouse architectures, the emergence of the data lake, and their use together. It also provides best practices to help organizations plan their unification strategies.

The principal author of the report, Fern Halper, is vice president and senior director of TDWI Research for advanced analytics. She explains that enterprises are accomplishing unification in several ways, including physical consolidation and using semantic layers and virtualization. She offers several examples of how enterprises are using these technologies today and explains that data lakes are not being used as a replacement for the data warehouse but as a complementary technology.

According to the report, “The two [technologies] have recently converged to form a new and richer data architecture. The architecture is fairly new, and not many organizations have embraced it yet.” The report explores the advantages of this convergence and how enterprises can maximize its benefits.

The report’s coauthor, James Kobielus, senior director of TDWI Research for data management, adds that nearly two-thirds of survey respondents said the point of the unified data warehouse/data lake is to get more business value from data, whether in operations or analytics.

Report Highlights

This comprehensive report reveals:

  • Top value drivers of the new architecture include unifying silos (53%), providing a better foundation for analytics of new and traditional data types (49%), and storage and cost considerations (28%)
  • When consolidating the technologies, enterprises may implement tools (such as data pipelines, data catalogs, and business glossaries) as well as data disciplines (including data governance, master data management, and metadata management)
  • Artificial intelligence’s many use cases are the principal driver behind the evolution of data warehouses into unified data warehouse/data lakes
  • Over a third (36%) of respondents report having either a data warehouse or a data lake in the cloud, indicating their mainstream acceptance
  • Modern software tools (even those not specifically designed for data governance) can assist with important practices and help scale data governance functions across the enterprise

Today’s drive to unify data warehouses and data lakes is focused on the need to enable data integration, interoperability, and cross-platform processes. The TDWI report examines these drivers and explores how enterprises view these demands as well as potential barriers that inhibit enterprises from successfully unifying their data warehouses and data lakes.

The report concludes with 8 recommendations for successful unification and comments about why each is important.

Platinum sponsors of this report include Denodo, Dremio, Matillion, Snowflake Computing, Trifacta, and Vertica. Qlik was a gold sponsor of the research.
