Data architecture is the discipline within information technology that defines how data is collected, stored, processed, and utilized within an organization. It involves designing and maintaining the systems, policies, and standards for managing data throughout its entire lifecycle, from creation to deletion. A well-designed data architecture should ensure that data is accurate, consistent, and accessible to those who need it, while also maintaining the security, privacy, and regulatory compliance of the data. It should also be scalable and flexible enough to accommodate changes in business needs, technology, and data sources. A solid data architecture is essential for effective decision-making, business intelligence, and data-driven innovation within an organization.
