Introduction to Databricks for Enterprise
Understand what Databricks is, the Lakehouse architecture that unifies data engineering and AI, and why it has become the platform of choice for enterprise data teams.
What is Databricks?
Databricks is a unified analytics platform built on Apache Spark that combines data engineering, data science, machine learning, and analytics into a single collaborative environment. Founded by the creators of Spark, Delta Lake, and MLflow, Databricks pioneered the Lakehouse architecture.
The Lakehouse merges the reliability and governance of data warehouses with the flexibility and cost-effectiveness of data lakes, providing a single platform for all data and AI workloads.
The Lakehouse Architecture
The Lakehouse combines the best of both worlds:
Open Storage
Data stored in open formats (Delta Lake, Parquet) on your cloud storage — no vendor lock-in or proprietary formats.
ACID Transactions
Delta Lake provides ACID transactions, schema enforcement, and time travel on data lake storage.
Unified Governance
Unity Catalog provides centralized access control, auditing, lineage, and data discovery across all assets.
Multi-Workload
Support for SQL analytics, streaming, data engineering, data science, and ML on a single copy of data.
