AT&T – World’s Largest Databases. AT&T can trace its origin back to the original Bell Telephone Company founded by Alexander Graham Bell after his invention of the telephone. One of that company’s subsidiaries was American Telephone and Telegraph Company (AT&T), established in 1885, which acquired the Bell Company on December 31, 1899 for legal reasons, leaving AT&T as the main company. AT&T established a network of subsidiaries in the United States and Canada that held a government-authorized phone service monopoly, formalized with the Kingsbury Commitment, throughout most of the twentieth century. This monopoly was known as the Bell System, and during this period, AT&T was also known by the nickname Ma Bell. For periods of time, the former AT&T was the world’s largest phone company. One of the oldest telecommunication companies, the American based AT&T has one of the largest databases. The company boasts that they have the largest volume of data in one unique database. Also AT&T has one of the largest database with most number of rows (around 1.9 Trillion), second to Sprint. It’s said that AT&T has been recording the details of callers long before terabytes storing came into market.

Daytona is AT&T’s database management system

daytona-is-atts-database-management-systemDaytona is AT&T’s database management system for warehousing immense amounts of data while providing the capability to quickly query and retrieve data within seconds, even from tables containing more than a trillion records. It supports such standard database functionality as SQL, data dictionary, transactions, locking, logging, recovery, and views. In addition, it offers indefinite size scalability via its compression technology and fully general horizontal partitioning, great speed scalability via its unique SPMD parallelization capabilities, special in-memory data structures, and optional shared memory use and lastly, its own powerful 4GL query language Cymbal, which includes SQL. It does all this in a more streamlined, better engineered way that sets Daytona apart from other database systems in terms of database capacity, speed, query language expressiveness, and ease of use.

Among its distinguishing characteristics is Daytona’s unique and simple architecture. First, there are no database server processes. While most database systems rely on server-based processes for scheduling, file access, locking, caching, networking and other tasks, Daytona employs the operating system alone for these tasks. This avoids the inefficiencies inherent in having both server processes and the operating system redundantly trying to do the same kinds of things at the same time on the same hardware. Thus, Daytona’s architecture enables it to be more compact and more efficient than other database systems.
