Digital Theater Systems: a multichannel audio codec format used in cinema and home theater. It is a major competitor to Dolby Digital with higher bitrates.

Native file format for AutoCAD, used for storing 2D and 3D design data. It is the most widely used CAD format in architecture, engineering, and construction.

Drawing Exchange Format: an open CAD data file format by Autodesk for interoperability between AutoCAD and other programs.

Drawing Exchange Format: an open CAD interchange format by Autodesk. Text-based variant widely supported by laser cutters, CNC machines, and 2D CAD software.

A client-optimized programming language developed by Google for building mobile, desktop, server, and web applications. Dart is the primary language for the Flutter framework and features sound null s...

A set of techniques used to artificially increase the size and diversity of training datasets by creating modified versions of existing data. Common methods include image rotation, flipping, cropping,...

A security incident in which sensitive, protected, or confidential data is accessed, disclosed, or stolen by an unauthorized party. Data breaches can result from hacking, malware, insider threats, or...

The process of assigning meaningful tags or annotations to raw data such as text, images, or audio to create training datasets for supervised learning. Data labeling quality directly impacts model acc...

A centralized storage repository that holds vast amounts of raw data in its native format until needed for analysis. Unlike data warehouses that store structured data, data lakes can store structured,...

A set of tools and policies designed to prevent sensitive data from being lost, misused, or accessed by unauthorized users. DLP solutions monitor, detect, and block the transfer of confidential inform...

A centralized repository that stores large volumes of structured data from multiple sources, optimized for analytical queries and reporting. Data warehouses use schemas like star and snowflake to orga...

A database object that enables traversal over the rows of a result set one at a time, rather than fetching all rows at once. Cursors are used for row-by-row processing in stored procedures, and in app...

A situation where two or more database transactions are waiting for each other to release locks, creating a circular dependency that prevents any of them from proceeding. Database engines detect deadl...

A data structure that improves the speed of data retrieval operations on a database table at the cost of additional storage space and slower write operations. Indexes are typically implemented using B...

A version-controlled, incremental change to a database schema that can be applied or rolled back. Migrations enable teams to evolve the database structure alongside application code, ensuring consiste...

The process of organizing a relational database to reduce data redundancy and improve data integrity. Normalization involves structuring tables according to normal forms (1NF, 2NF, 3NF, BCNF) to elimi...

The technique of dividing a large database table into smaller, more manageable pieces (partitions) while still treating them as a single logical table. Partitioning strategies include range, list, has...

The process of copying and maintaining database data across multiple servers to ensure consistency, high availability, and disaster recovery. Common strategies include master-slave replication, master...

The formal structure that defines how data is organized in a database, including tables, columns, data types, relationships, constraints, and indexes. A schema serves as a blueprint for the database a...

A horizontal scaling strategy that distributes data across multiple database instances (shards), each holding a subset of the total data. Sharding improves performance and capacity by allowing paralle...
