La base de datos se presenta como una biblioteca de JavaScript y permite el uso del lenguaje SQL. Se admite el almacenamiento de datos en tablas relacionales tradicionales o en estructuras JSON anidadas, que no requieren una definici\u00f3n r\u00edgida de esquema de almacenamiento. Para manipular datos desde la l\u00ednea de comandos, se proporciona la utilidad alasql. El c\u00f3digo del proyecto est\u00e1 escrito en JavaScript y se distribuye bajo la licencia MIT.    <\/p>\n<p>AlaSQL admite la mayor\u00eda del lenguaje SQL-99, as\u00ed como complementos para el procesamiento al estilo NoSQL (sin definici\u00f3n de esquema de almacenamiento) y manipulaci\u00f3n de grafos. En las consultas SQL se pueden realizar operaciones de uni\u00f3n (JOIN), agrupamiento (GROUP), combinaci\u00f3n (UNION), utilizar subconsultas y expresiones como ANY, ALL e IN, aplicar funciones ROLLUP(), CUBE() y GROUPING SETS(). Hay soporte limitado para transacciones. Se admite la definici\u00f3n de funciones personalizadas que se pueden usar en consultas SQL. Para una llamada r\u00e1pida, la funci\u00f3n y las expresiones SQL pueden ser compiladas (an\u00e1logo al operador SQL PREPARE).     <\/p>\n<p>La base de datos AlaSQL est\u00e1 dise\u00f1ada para utilizar la paradigma ETL (Extraer, Transformar, Cargar) y manipular datos en forma de importar\/procesar\/exportar. Para almacenamiento, exportaci\u00f3n e importaci\u00f3n se pueden usar formatos como localStorage, IndexedDB, CSV, TAB, TXT, JSON, SQLite y Excel (.xls y .xlsx), suponiendo que se pueden ejecutar consultas directamente sobre los datos almacenados en los formatos mencionados, o importar y exportar datos. Tambi\u00e9n es posible ejecutar operaciones SELECT sobre cualquier dato en objetos JavaScript.    <\/p>\n<p>La biblioteca est\u00e1 dise\u00f1ada para un procesamiento r\u00e1pido de datos en memoria para aplicaciones de an\u00e1lisis empresarial y soporta optimizaciones como el almacenamiento en cach\u00e9 de consultas en forma de funciones compiladas, la indexaci\u00f3n proactiva de la fusi\u00f3n de tablas y la filtraci\u00f3n de expresiones WHERE antes de las operaciones de fusi\u00f3n. En comparaci\u00f3n con otros proyectos similares, AlaSQL ha demostrado ser tres veces m\u00e1s r\u00e1pido que SQL.js en consultas con operaciones SUM, JOIN y GROUP BY, dos veces m\u00e1s r\u00e1pido que Linq al usar GROUP BY y aproximadamente al mismo nivel que la API WebSQL (una capa sobre SQLite que pronto se eliminar\u00e1 de Chrome) en consultas con operaciones SUM, JOIN y GROUP BY.<br
