A DTU is defined as a blended measure of CPU, memory, and data I / O and transaction log I / O in a ratio determined by an OLTP benchmark workload designed to be typical of real-world OLTP workloads.

Most database management systems do not document the internal format of their transaction logs, although some provide programmatic interfaces to their transaction logs ( for example : Oracle, DB2, SQL / MP, SQL / MX and SQL Server 2008 ).
