  • Data Mart

    Data mart is a subject-focused subset of a data warehouse that contains curated, structured data for a specific business domain or department, enabling targeted analytics, reporting, and governance within enterprise data platforms and business intelligence environments.

  • Data Masking

    Data masking is a data protection technique that alters sensitive data into de-identified or pseudonymous values while preserving structure, enabling development, testing, analytics, and data sharing on realistic datasets while limiting exposure of personal, financial, or regulated information in enterprise environments.

  • Data Mediation Platform

    Data mediation platform is an intermediate software layer that standardizes, enriches, and routes data between heterogeneous systems, enabling consistent formats, centralized transformation logic, and policy enforcement for billing, analytics, and compliance use cases in complex enterprise environments.

  • Data Memory

    Data memory is the hardware or software-managed working storage that holds data values, variables, and intermediate results during program execution, which matters in enterprise computing for performance, reliability, and security of applications, platforms, and in-memory processing architectures.

  • Data Mesh

    Data mesh is an enterprise data management approach that assigns domain teams ownership of data as a product, supported by a self-serve data platform and federated governance, to manage distributed data, quality, and access across complex organizational and technology environments.

  • Data Mesh Architecture

    Data mesh architecture is a decentralized data management approach that assigns domain-based ownership for data products while enforcing shared standards, governance, and self-serve platform capabilities, enabling enterprises to manage analytics and AI data across many domains with consistent controls and interoperability.

  • Data Migration

    Data migration is the controlled transfer of data between systems, formats, or environments within an enterprise, conducted through defined processes to preserve integrity, security, and usability while supporting system changes, cloud adoption, consolidation efforts, and regulatory and governance requirements.

  • Data Migration Service

    Data migration service is a software-based capability that automates and governs the movement of data between systems or environments, enabling secure, controlled transitions during modernization, consolidation, or cloud adoption while maintaining data quality, integrity, security controls, and business continuity requirements.

  • Data Minimization

    Data minimization is a privacy and data protection principle that limits personal data collection, processing, and retention to what is adequate, relevant, and necessary for defined purposes, helping enterprises meet regulatory requirements and reduce exposure of unnecessary personal information.

  • Data Mirroring

    Data mirroring is a data protection method that maintains near-real-time duplicate copies of data on separate systems or sites, enabling high availability, controlled failover, and disaster recovery to support enterprise continuity, resilience objectives, and regulatory or contractual uptime requirements.

  • Data Mobility Platform

    Data mobility platform is an integrated software or software-defined system that manages secure, policy-governed movement and placement of data across heterogeneous storage, cloud, and edge environments, supporting workload portability, governance, and compliance in enterprise and hybrid cloud architectures.

  • Data Modeling

    Data modeling is the formal process of defining and documenting how data entities, attributes, and relationships organize within information systems so enterprises can implement consistent schemas, governance, integration, analytics, and controls across operational and analytic data platforms.

  • Data Modeling Framework

    Data modeling framework is a structured set of methods and artifacts that organizations use to design, document, and govern data models across conceptual, logical, and physical layers, supporting consistent data definitions, change management, and alignment between business requirements and implemented data structures.

  • Data Modeling Layer

    Data modeling layer is an abstraction layer in enterprise data architectures that defines and exposes consistent, business-ready logical data models, allowing organizations to standardize metrics and entities while insulating analytics and applications from changes in underlying data sources and storage.

  • Data Movement Minimization

    Data movement minimization is an architectural and governance approach that reduces how much and how often enterprise data is transferred between systems and locations, helping control cost, latency, attack surface, and regulatory exposure while preserving required processing and analytics.

  • Data Networks

    Data networks are interconnected digital communication systems that move data between devices, applications, and locations using standardized protocols, enabling enterprise connectivity, application delivery, and secure access to computing and data resources across campuses, data centers, WANs, edge sites, and cloud environments.

  • Data Normalization

    Data normalization is the process of organizing and transforming data to reduce redundancy, enforce consistency, and align values to common scales, enabling reliable storage, analysis, and machine learning across enterprise databases, data warehouses, and analytics platforms.

  • Data Obfuscation

    Data obfuscation is a data protection technique that alters or masks data to limit unauthorized disclosure while keeping it usable for defined enterprise purposes. It matters because it enables analytics, testing, and data sharing while constraining exposure of sensitive or regulated information.

  • Data Observability

    Data observability is a set of practices and tools that monitor and analyze the health of enterprise data and data pipelines, supporting reliable analytics, governance, and compliance by providing continuous visibility into data quality, reliability, and pipeline behavior.

  • Data Observability Platform

    Data observability platform is enterprise software that monitors and analyzes the health, quality, and reliability of data across pipelines and storage systems, enabling organizations to detect anomalies, manage incidents, and maintain service levels for analytics, reporting, and machine learning workloads.
