The Data Lakehouse:

Foundation for scaling AI-based innovation across the enterprise

March 28, 2025

In the era of big data, advanced analytics, and AI, the need for efficient data management systems becomes critical. Traditional data warehousing and data lake architectures have their limitations, particularly in navigating through diverse and voluminous datasets, making it extremely difficult for users to get to relevant, contextualized data. Traditional data architectures suffer from these problems:

The need for a holistic approach

Data Accessibility

Running analytical queries on large and diverse datasets is challenging, and it becomes extremely difficult for users to find and get contextualized data out. This also means that the existing architecture can only provide limited support for advanced analytics and AI as these algorithms need to process large datasets using complex querying.

Collaboration Bottlenecks

Lack of a shared, unified, and contextual data view causes challenges for team collaboration across the organization, often leading to redundant data acquisition and data management activities. In most cases, the data does not adhere to the FAIR (acronym for Findable, Accessible, Interoperable, and Reusable) principles, and hence, does not allow users to exploit the full potential of the data.

Data Integrity Issues

Keeping the data lake and data warehouse consistent is difficult and costly because of redundancies. Lack of a semantic layer impacts analysis integrity.

The concept of a data lakehouse, which integrates the best features of both data lakes and data warehouses and adds a semantic layer for contextualization, emerges as a compelling solution.

A data lakehouse is an open data management architecture that combines the flexibility, cost-efficiency, and scale of data lakes with the data management capabilities of data warehouses. It enables dashboarding, traditional AI, generative AI, and AI-based applications on accessible and transparent data.

Unpacking the Data Lakehouse Advantage:

The following are the core components of a holistic data lakehouse strategy. The technology helps elevate the data strategy of organizations and accelerates velocity to value across the value chain:

Data Ingestion (Easy to Get Data In)

The data lakehouse makes it “easy to get data in”, coming with pre-built standard connectors to various systems and instruments, supporting both real-time and batch ingestion, and providing features for data transformations at various stages. The overlay of a semantic layer enables data ingestion processes to utilize the semantic definitions. Knowledge graphs can integrate data from various sources, including structured, semi-structured, and unstructured data, and help create a cohesive representation of information stored in the lakehouse.

Data Leverage (Easy to Get Data Out)

The data lakehouse comes with robust data management features. The business metadata management is powered by knowledge graphs, providing ontology management and knowledge modeling capabilities. It adheres to the FAIR principles (i.e., makes data Findable, Accessible, Interoperable, and Reusable), thus making it “easy to get data out”.
  • By defining semantic relationships and hierarchies between data entities, knowledge graphs provide rich domain context that enhances data understanding and usability. This allows users to navigate through data based on relationships rather than just rely on raw data of technical data dictionaries.
  • Connecting the Semantic Layer to the Analysis layer allows the use of contextualized semantic business terms for analytics. It enables efficient querying of data in natural language and provides contextual responses that are easy to use, understand, and interpret.
  • Knowledge graphs can enrich data by linking it with external datasets or ontologies, providing additional context that can improve analysis and insights.

Reference Architecture:

Leveraging our end-to-end AI platform, tcgmcube, organizations can create robust data lakehouses, with the aim to streamline data management by integrating various data processing and analytics needs into one architecture. This approach helps avoid redundancies and inconsistencies in data, accelerates analysis throughput, and minimizes costs.

The platform tcgmcube provides advanced analytics/AI capabilities and data management on the same platform managed by common platform services. This makes it an extremely powerful platform for implementing the lakehouse and deploying analytical and AI applications on top of the lakehouse.
