Ever since computing started to be used commercially, data serving has been a key element in business use of information technology. Ensuring that applications and their users have access to the data they need is critical to supporting business processes. Historically, the mainframe has performed the role of a central data server for many large enterprises, taking advantage of its typically high data throughput, scalability and strong security and resiliency capabilities. This has made it an excellent choice as a data server to help support mission critical core business applications. However over time, as businesses and their infrastructures have evolved with multi-tier solutions and technology spread across the company, so corporate data has become more fragmented across the infrastructure.
