JSSQL is a database engine developed entirely with JavaScript. It is a tool for developers to interpret and execute SQL statements on a offline database. It has a conversion class developed in PHP for use with relational databases (ex. PostgreSQL, MySQL, etc..) that generates a series of data files, then the database engine in JavaScript (JSSQL) accesses the data through SQL querys and return a set of records, similar to any database engine. This is useful for querying offline databases dynamically without increasing the work of the web server or better yet: without the need for a database server A database engine entirely in JavaScript (AJAX). Un motor de bases de dato enteramente en JavaScript. Es una herramienta para desarrolladores que permite interpretar y ejecutar sentencias SQL sobre una base de datos de manera offline. JavaScript (JSSQL) accede a datos mediante consultas SQL devolviendo un conjunto de registros de manera similar a cualquier motor de bases de datos.
