Advanced Database Crossword Puzzle

QUESTIONS LIST:

• bitemporal relation : a complex temporal database structure that associates both valid and transaction time with each data tuple.
• structured data : data that adheres to a fixed schema and is typically stored in relational databases using tables, columns, and rows.
• temporal integrity : a constraint in temporal databases that ensures consistency and accuracy of time-related data such as valid and transaction times.
• encapsulation : a principle in object databases where object data and behavior are packaged together to enforce modularity and information hiding.
• replication : a technique in distributed databases where multiple copies of data are maintained across different sites for fault tolerance and availability.
• fragmentation : a distributed database strategy that divides data across sites by rows, columns, or a combination of both to improve performance and localization.
• x query : a powerful query language designed for querying and transforming xml data, supporting iteration, filtering, and function calls.
• class inheritance : an object-oriented feature where a new class can acquire the attributes and behaviors of an existing class in a database schema.
• object identity : a distinguishing feature of object-oriented databases that allows objects to be uniquely identified independent of their values.
• odmg : a consortium that defines standard object-oriented database models, including schema, query, and manipulation languages.
• complex objects : structured objects that can include other objects, arrays, or sets, and are supported in object-based databases for rich data modeling.
• interoperability : the ability of different database systems and applications to work together and exchange data meaningfully, often aided by xml schemas and dtds.
• semi structured data : data that does not conform to a fixed schema but contains tags or markers to separate data elements, common in xml.
• native xmldb : a category of databases that store and process xml data natively, enabling efficient handling of deeply nested documents.
