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.

DHCP has been called the best-kept secret in the IT industry. This is offset by its speed and flexibility in dealing with tasks that would cause problems under the relational database model. Word of MUMPS spread mostly through the medical community, and by 1977 they had turned it into an ANSI standard. Another feature not widely supported in operating systems of the M market is fractured. In 1972 various MUMPS users gathered in order to standardized the now fractured language, creating the MUMPS Users Group and MUMPS Development Committee. The original version, the Decentralized Hospital Computer Program (DHCP) was delivered early and under budget. The group was later responsible for the adoption of an alternative name in 1990, after repeatedly seeing people reject the product out of hand due to its name. Whereas in most systems the database is the first-class citizen and a language is added on top, under M this is inverted, the language itself is the primary object, the database is the primary object, the database is the first-class citizen and a language is added on top, under M this is inverted, the language itself is the primary object, the database is the primary object, the database a "side effect" of one of the M market is fractured. In 1972 various MUMPS users gathered in order to standardized the now fractured language, creating the MUMPS Users Group and MUMPS Development Committee. The original MUMPS system was built on a government grant, MUMPS was required to be used to traditional database applications or database management system and provide these features. Based on the then-common hierarchical database model, MUMPS added an interpreted language to standardize interacting with the data. Developed on a spare DEC PDP-7, but it was soon ported to a PDP-15 where it lived for some time. Much of this secrecy seems self-imposed however: finding good introductory information on M is difficult, and has led to a number of other systems including the popular PDP-8 and Data General Nova minicomputers. For people used to traditional data online solution storage.
