Tellius helps to bridge the gap between data and decisions with true natural language search analytics on billions of rows of data and AI-powered decision intelligence. Combining the flexibility of Delta Lake with Tellius empowers everyone, from data scientists to data analytics and business users, with access to mission-critical business insights.

Delta Lake + the Databricks Lakehouse Platform

For years, data lakes have been touted as the next evolution of the data storage paradigm, and many organizations today leverage data lakes in their data architecture. Data lakes are highly scalable and have the ability to store many different types of data, including structured, semi-structured, and unstructured data, at a very low cost. Because data lakes have no predefined schema, they offer the flexibility to hold a wide variety of data, including images, videos, NoSQL databases, time-series data, and much more. They can help organizations centralize their data architecture and eliminate silos by providing a repository for all data.

At the same time, many organizations have struggled with the full promise of the data lake. Because data lakes were not initially thought of as a place for production analytics, they were used as a low-cost storage solution for a company’s flood of raw data. The utilization of a data warehouse was largely seen as a result of the real or perceived lack of performance and reliability from a data lake architecture. Even so, as data usage becomes more intensive at organizations, the cost and problems associated with managing a data warehouse only rise. Companies also have increasingly realized the business risk associated with vendor lock-in due to the proprietary storage formats of data warehouses. This has led organizations to look for new solutions to the problem of managing data and also led to the rise of the open data lakehouse paradigm.

Delta Lake makes data on the data lake more accessible and reliable by providing data warehouse-like capabilities on top of the lake. Delta Lake is an open-storage format layer optimized for file-based storage. It includes metadata, caching, and indexing and is compatible with query engines like Apache Spark, Apache Hive, Presto, and Trino. It essentially combines the best aspects of the data warehouse—reliability and performance—with the scale of a data lake. Delta Lake does this by leveraging Parquet files with a file-based transaction log for ACID transactions and scalable metadata handling. As an open-source format storage layer, Delta Lake reduces the business risk of vendor lock-in. Taken in aggregate, Delta Lake has made the promise of the open data lakehouse into a reality for many organizations.

What is AI-Powered Decision Intelligence?

While Databricks and Delta Lake have been redefining how companies leverage data lakes in their data architecture, legacy business intelligence has been undergoing a similar evolution with new decision intelligence platforms like Tellius. Legacy business intelligence platforms are designed to focus on descriptive analytics, which can take the form of reports, dashboards, and other static ways for organizations to understand how their data is changing. A business intelligence user needs to analyze the information available in these dashboards and synthesize the analysis into insights. This requires a deep understanding of the data and the ability to analyze the data to find these key insights. This process can be time-consuming and restricts insight generation to a limited group of people in the organization.

AI-powered decision intelligence is the next step in the evolution of business intelligence. Decision intelligence provides not just descriptive, but also diagnostic and predictive, analytics to the end user. These platforms deliver dynamic recommendations on the best next steps to a problem and can utilize natural language to simplify the process of moving from a business question to a data search query. Decision intelligence helps democratize data by providing intelligent automation to insight generation by leveraging AI throughout the platform, dramatically shortening the path from business question to data-driven decision. Decision intelligence can help unlock self-service analytics by augmenting users’ ability to deliver insights across the organization.

Tellius was designed from the ground up to leverage AI throughout its platform to help organizations move from mission-critical problems to answers faster than ever. The platform includes natural language search, arming more people in an organization with a tool to ask questions of the data. Tellius also leverages AI-driven automation and data analysis to uncover key drivers, patterns, anomalies, and segments. This automated insight generation saves analysts, data scientists, and business users hours or even days of analysis work. In fact, the entire data lifecycle has been automated with Tellius, including automated data prep, visualizations, insights, machine learning, and more. Tellius provides a path for your entire organization to deliver self-service analytics and become truly data-driven.
