Norma Z39.50, actualidad, posibilidades. ¿Es necesario un cambio de actitud?

Revista Española de Documentación Científica, 1998
La tecnología de los sistemas basados en la norma Z39.50 ofrece numerosas posibilidades, a priori bastante prometedoras. Conectividad de sistemas, recuperación de información muy estructurada, redefinición de aplicaciones (robots de búsqueda, agentes...),

CoSQL: A Conversational Text-to-SQL Challenge Towards Cross-Domain Natural Language Interfaces to Databases [PDF]

Conference on Empirical Methods in Natural Language Processing, 2019
We present CoSQL, a corpus for building cross-domain, general-purpose database (DB) querying dialogue systems. It consists of 30k+ turns plus 10k+ annotated SQL queries, obtained from a Wizard-of-Oz (WOZ) collection of 3k dialogues querying 200 complex ...

CHOOSING THE APPROPRIATE DATABASE TYPE: A COMPARISON OF SQL, NOSQL, AND NEWSQL [PDF]

Analele Universităţii Constantin Brâncuşi din Târgu Jiu : Seria Economie
Databases are data collections organized for easy access and management, available simultaneously to multiusers. Access to the data can be controlled through various permissions, ensuring that users have the appropriate level of access based on their

Multi-Model Database Systems: The State of Affairs [PDF]

Annals of Dunarea de Jos University. Fascicle I : Economics and Applied Informatics, 2020
Nowadays, more and more organizations are coping with a very large volume of data in different formats and a very high growth rate. Under these conditions, relational databases are no longer sufficient for data management within these organizations, as ...

AE-Net: Novel Autoencoder-Based Deep Features for SQL Injection Attack Detection

IEEE Access, 2023
Structured Query Language (SQL) injection attacks represent a critical threat to database-driven applications and systems, exploiting vulnerabilities in input fields to inject malicious SQL code into database queries.

Assessing Structural Classification Using AlphaFold2 Models Through ECOD‐Based Comparative Analysis

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Identifying homologous proteins is a fundamental task in structural bioinformatics. While AlphaFold2 has revolutionized protein structure prediction, the extent to which structure comparison of its models can reliably detect homologs remains unclear.

Compiling PL/SQL Away [PDF]

arXiv, 2019
"PL/SQL functions are slow," is common developer wisdom that derives from the tension between set-oriented SQL evaluation and statement-by-statement PL/SQL interpretation. We pursue the radical approach of compiling PL/SQL away, turning interpreted functions into regular subqueries that can then be efficiently evaluated together with their embracing ...

Structured Query Language Learning: Concept Map-Based Instruction Based on Cognitive Load Theory

IEEE Access, 2020
Structured query language (SQL) is difficult to master because the execution process of SQL statements is invisible. When learning to construct an SQL query, learners must visualise the evolution process of the intermediate datasets of the SQL statement ...

Multi‐Photon Fock State Generation via Selective Single Photon Subtraction in a Cascaded Waveguide QED System

Advanced Quantum Technologies, EarlyView.
This work proposes a photon subtraction scheme, termed ′photon culling′, that enables the selective extraction of a single photon based on its arrival time relative to other photons. This scheme enables the generation of multi‐photon Fock states with high fidelity and modal purity, demonstrating significant potential for quantum metrology applications ...
