This paper introduces the Accelerated Data Delivery Architecture (ADDA). ADDA establishes a framework to distribute transactional data and control consistency to achieve fast access to data, distributed scalability and non-blocking concurrency control by using a clean declarative interface. It is designed to be used with web-based business applications. This framework uses a combination of traditional Relational Database Management System (RDBMS) combined with a distributed Not Only SQL (NoSQL) database and a browser-based database. It uses a single physical and conceptual database schema designed for a standard RDBMS driven application. The design allows the architect to assign consistency levels to entities which determine the storage location and query methodology. The implementation of these levels is flexible and requires no database schema changes in order to change the level of an entity. Also, a data leasing system to enforce concurrency control in a non-blocking manner is employed for critical data items. The system also ensures that all data is available for query from the RDBMS server. This means that the system can have the performance advantages of a DDBMS system and the ACID qualities of a single-site RDBMS system without the complex design considerations of traditional DDBMS systems.
