JBSqlUtils es un ORM desarrollado en java por José Carlos Alfredo Bran Aguirre,
que permite gestionar BD's SQLite, MySQL, MariaDB, PostgreSQL y SQLServer, de una manera fácil
y rápida sin interrumpir la ejecución del hilo principal del programa, lo cual la hace un potente ORM,
por medio del cual tendrá acceso a un CRUD, configurando únicamente la conexión del
modelo, los atributos que posee la tabla en BD's cómo variables que pertenecerán al modelo en su aplicación.
JBSqlUtils también proporciona un potente generador de instrucciones SQL que le permitirá crear
o eliminar una tabla, insertar, seleccionar, actualizar o eliminar registros de una tabla
en su BD's sin necesidad de instanciar un modelo cómo tal, únicamente tendrá que configurar previamente
la conexión a su BD's.
Lo cual la hace un potente ORM para aplicaciones android y sistemas empresariales que tengan
la necesidad de poder conectarse a alguna de estas 4 tipos de BD's, cabe mencionar que para ello utiliza
el SQLite JDBC de org.xerial, org.postgresql, mysql y com.microsoft.sqlserver.
