1. A method for efficient use of a relational database by a processor device in a computing environment, the method comprising: executing a plurality of concurrent transactions on the single database schema using a single concurrent transaction database infrastructure, wherein the single database schema is a single concurrent transactional relational database; combing a plurality of databases to expose the single database schema for providing a plurality of concurrent transactions on the single database schema using the single concurrent transactional relational database, wherein character traits and behaviors of a transactional relational database executing multiple concurrent transactions are maintained; calculating a plurality of parameters for controlling a tradeoff between at least each of concurrency, throughput, and latency; initializing a semaphore for controlling the plurality of concurrent transactions; and executing a plurality of concurrent transactions on the single database schema in parallel on the single database schema using the single concurrent transaction database infrastructure.
