AceQL HTTP is a framework of REST like http APIs that allow to access to remote SQL databases over http from any device that supports http. AceQL HTTP is provided with four client SDK: - The AceQL C# Client SDK allows to wrap the HTTP APIs using Microsoft SQL Server like calls in their code, just like they would for a local database. - The AceQL Java Client SDK allows to wrap the HTTP APIs using JDBC calls in their code, just like they would for a local database. - The AceQL Python Client SDK allows SQL calls to be encoded with standard unmodified DB-API 2.0 syntax

There is a newer version: 12.2
