Смысл: The main idea is to demonstrate that Oracle Database provides a powerful and flexible set of built-in tools (XMLType, extractValue, XMLSequence, and XMLTable) that allow developers to treat XML data as relational data, facilitating easier data analysis and system integration without needing external application logic.
A technical guide demonstrating how to use Oracle Database's XMLType and related functions to parse, flatten, and query XML data using SQL.
Смысл: The main idea of the text is to serve as a technical reference for Oracle developers on how to implement, manipulate, and optimize collections in PL/SQL to improve data handling and application performance.
A detailed technical guide covering the types, methods, set operations, and performance optimizations (Bulk Collect/FORALL) of collections in Oracle PL/SQL.
Смысл: The main idea is to demonstrate how SQL Server 2016 integrates JSON capabilities, allowing developers to store, query, modify, and export JSON data while maintaining the power of a relational database.
A comprehensive guide on using SQL Server 2016's built-in functions and clauses to manage JSON data within a relational database environment.
Смысл: The main idea is to compare Relational and Object-Oriented databases, highlighting that while OODBMS offer a more natural fit for OOP programming, they lack the standardization and mathematical rigor that make RDBMS globally dominant.
The author discusses the trade-offs between relational and object-oriented databases, arguing that despite the convenience of ORM, the lack of standards and a mathematical foundation hinders the adoption of OODBMS.
Смысл: The text serves as a technical guide on how to perform queries using the JSONB data type in PostgreSQL. It explores various operators for equality, containment, and key existence, while warning users about the pitfalls of storing mixed JSON types (arrays vs. objects) in the same column.
A technical exploration of PostgreSQL JSONB operators, highlighting how to handle mixed data types and the transition toward Django ORM integration.
