  • Data Custodian

    Data custodian is a role that operates and administers the technical and procedural controls that store, process, and protect data under policies set by data owners and governance bodies, supporting compliance, risk reduction, and reliable data operations in enterprises.

  • Data Deduplication

    Data deduplication is a data reduction technique that identifies redundant copies of data and stores a single unique instance referenced by pointers, which helps enterprises reduce storage capacity requirements and improve efficiency in backup, archival, and disaster recovery environments.

  • Data Definition Language

    Data definition language is the subset of SQL that defines and manages database schemas and related objects, enabling enterprises to specify structures, constraints and metadata for data storage, governance, performance tuning and controlled schema evolution across operational and analytical systems.

  • Data De-Identification

    Data de-identification is a controlled process that alters or removes identifiers from datasets so individuals are not readily identifiable, enabling analytics, sharing, and reuse of data in enterprises while reducing privacy, regulatory, and security risk exposure.

  • Data Dependency Graph

    Data dependency graph is a directed graph representation that models how data elements and computations depend on each other in software, analytics, or data workflows, enabling structured analysis, optimization, impact assessment, and governance in enterprise-scale systems and data platforms.

  • Data Diode

    Data diode is a hardware-enforced unidirectional network device that permits data to flow only in one direction between networks, used to export information from high-security or safety-critical environments while reducing exposure to inbound cyber threats and remote compromise.

  • Data Discovery

    Data discovery is the process and tooling that scan, profile, classify, and catalog enterprise data assets so organizations know what data they have, where it resides, and how it is used, supporting governance, security, compliance, and analytics use cases.

  • Data Downlink

    Data downlink is the transfer of data from a remote platform, such as a satellite, spacecraft, aircraft, or unmanned system, to ground-based receivers, supporting telemetry, payload delivery, and enterprise data ingestion for monitoring, analytics, and operational decision processes.

  • Data Downlink Station

    Data downlink station is a ground-based facility that receives, demodulates, and processes data transmitted from satellites or aerial platforms into digital streams for terrestrial networks, affecting availability, latency, and security of space-derived data used in enterprise operations and services.

  • Data Drift

    Data drift is the change over time in the statistical properties of input data used by a model or analytics system compared with its training or baseline data, and it matters because unmanaged drift can degrade reliability and require governance action.

  • Data Drift Detection

    Data drift detection is the process of monitoring changes in the statistical properties of data over time to identify when deployed analytical or machine learning models operate under conditions different from their training data, supporting governance, reliability, and model risk management.

  • Data Durability

    Data durability is the quantified probability that stored data remains intact and retrievable over time without loss. It matters in enterprise contexts because it underpins compliance, continuity, and risk decisions for storage platforms, backups, archives, and disaster recovery architectures.

  • Data Egress Optimization

    Data egress optimization is the practice of controlling and reducing outbound data transfers from clouds, data centers, and networks to manage cost, bandwidth, and compliance while maintaining required performance, security, and availability for enterprise workloads and data flows.

  • Data Encoding Layer

    Data encoding layer is an architectural component that converts raw data into standardized encoded representations for storage, transmission, and processing, enabling consistent interoperability, performance tuning, and controlled data handling across enterprise applications, integration platforms, and communication or storage systems.

  • Data Encryption

    Data encryption is a cryptographic process that converts readable data into ciphertext using algorithms and keys, enabling enterprises to protect confidentiality of data at rest and in transit, meet regulatory requirements, and reduce exposure from unauthorized access or interception.

  • Data Encryption At Rest

    Data encryption at rest is the application of cryptography to data stored on persistent media so it remains unreadable without decryption keys, helping enterprises address storage-related threats, regulatory requirements, and internal security policies for databases, files, backups, and cloud storage.

  • Data Encryption In Transit

    Data encryption in transit protects data confidentiality and integrity while it moves between endpoints, networks, or cloud services using cryptographic protocols and keys. It matters in enterprises because regulations, zero trust architectures, and security baselines require protected communications across internal and external connections.

  • Data Encryption Key

    Data encryption key is a cryptographic key used to encrypt and decrypt data in enterprise systems, typically within a hierarchical key management architecture, and is central to enforcing confidentiality controls and meeting security and compliance requirements for data at rest and in transit.

  • Data Encryption Standard

    Data Encryption Standard (DES) is a symmetric-key block cipher that encrypts 64-bit data blocks with a 56-bit key and served as a U.S. federal standard; in enterprises it now appears mainly in legacy systems and deprecation planning.

  • Data Ethics Charter

    Data ethics charter is a formal document that sets out an organization’s principles, rules, and governance commitments for responsible data collection, processing, and use, providing a reference point for aligning data, analytics, and AI practices with defined ethical and regulatory expectations.
