Data Online Solution Storage

When an application is built, an underlying data model is chosen to make that application effective. Frequently, other applications need the same data, only modeled differently. The naive solution of copying the underlying data and modeling is costly in terms of storage and makes data maintenance and evolution impossible. View mechanisms are a technique to model data differently for various applications without affecting the underlying format and structure of the data. The technique enables applications to customize shared data objects without affecting other applications that use the same objects. The growing data-manipulation needs of companies cannot be met by existing legacy systems that contain valuable data. Thus view mechanisms are becoming increasingly important as a way to model and use legacy data in new applications. Materialized views are views that have been computed and stored in databases. Because they reduce the need to recompute the view and/or data being queried, they speed up the querying of large amounts of data. Further, because they provide a systematic way to describe how to recompute the data, maintenance and evolution can be automated. Materialized views are especially useful in data warehousing, query optimization, integrity constraint maintenance, online analytical processing, and applications such as billing, banking, and retailing. This comprehensive volume, with a foreword by Jeff Ullman of Stanford University, will serve as a reference for students and commercial users, and encourage further use and development of materialized views.

Nearline storage - Nearline storage is a term used in computer science to describe an intermediate type of data storage. It is a compromise between online storage (constant, very rapid access to data) and offline storage (infrequent access for backup purposes or long-term storage).

Veritas Storage Foundation - Veritas Storage Foundation (VxSF) also known as Veritas Foundation Suite combines Veritas Volume Manager (VxVM) and Veritas File System (VxFS) to provide a complete solution for online storage management.

Digital Data Storage - Digital Data Storage (DDS) is a format for storing and backing up computer data on magnetic tape that evolved from Digital Audio Tape (DAT) technology, which was originally created for CD-quality audio recording. In 1989, Sony and Hewlett Packard defined the DDS format for data storage using DAT tape cartridges.

Data storage device - In computing, a data storage device—as the name implies—is a device for storing data. It usually refers to permanent (non-volatile) storage, that is, the data will remain stored when power is removed from the device; unlike semiconductor RAM.

Much of this secrecy seems self-imposed however: finding good introductory information on M is difficult, and the commercial side of the M market is fractured. The Veteran's Administration (today known as the programming language dedicated to building and managing databases. These efforts proved successful; a standard was complete by 1974, and by 1977 they had turned it into an ANSI standard. This is offset by its speed and flexibility in dealing with tasks that would cause problems under the relational database model. M contrasts strongly with most database systems, because the system is much "lower level". The original version, the Decentralized Hospital Computer Program (DHCP) was delivered early and under budget. Word of MUMPS spread mostly through the medical community, and by 1977 they had turned it into an ANSI standard.
