The Impact of Data Lake Architectures on Business Intelligence: An Empirical Study of Data-Driven Decision-Making in Large Enterprises
Main Article Content
Abstract
Data lakes have become a vital component of modern data architecture, offering organizations the flexibility to store and manage diverse data types at scale. However, the inherent flexibility of data lakes also introduces challenges, particularly in maintaining data quality and ensuring accessibility. This paper systematically examines architectural design patterns that address these challenges, focusing on best practices for ensuring data quality and accessibility within data lakes. Key patterns explored include data ingestion and validation strategies, data cleaning and transformation processes, and data lineage and provenance tracking, all of which contribute to maintaining high data quality. Additionally, the paper discusses patterns that enhance data accessibility, such as data cataloging and metadata management, data partitioning and indexing, and robust data access control mechanisms. The paper also emphasizes the importance of adopting a unified data governance framework, continuous monitoring and improvement practices, and a modular, scalable architecture. These best practices are critical for organizations aiming to optimize their data lake environments for long-term success, ensuring that data remains accurate, consistent, and accessible to support data-driven decision-making. Through a review of existing literature and case studies, this study provides a comprehensive guide to designing and managing data lakes that effectively balance flexibility with the need for high-quality, accessible data.
