JNoSQL: The Definitive Solution for Java and NoSQL Databases
Download as PPTX, PDF0 likes205 views
The document presents a discussion on NoSQL databases by speakers Otávio Santana and Werner Keil, exploring various types of NoSQL databases such as key-value, document, and graph databases. It highlights challenges associated with NoSQL, solutions like Eclipse JNoSQL, and details like data mapping and querying. The document also outlines the Eclipse project's roadmap and calls for community feedback on the new specifications related to Jakarta EE.
