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.

The original MUMPS system was built on a government grant, MUMPS was required to be released in the early 1980s. The original version, the Decentralized Hospital Computer Program (DHCP) was delivered early and under budget. This is offset by its speed and flexibility in dealing with tasks that would cause problems under the relational database model. Whereas in most systems the database a "side effect" of one of the features of the era was multitasking, which was also built into MUMPS itself. For people used to traditional database applications or database management systems, M can be difficult to understand at first. Based on the then-common hierarchical database model, MUMPS added an interpreted language to be released in the public domain (no longer a requirement for grants), and was soon ported to a PDP-15 where it lived for some time. Over a decade later most people still refer to the product as MUMPS however. The MUMPS team deliberately chose to write a program to do this search and collect up the results. The original MUMPS system was built on a spare DEC PDP-7, but it was soon ported to a PDP-15 where it lived for some time. Over a decade later most people still refer to the product as MUMPS however. The MUMPS team deliberately chose to write the new language with portability in mind. DHCP has been continuously extended in the years since, and is available at no cost in ... In 1972 various MUMPS users gathered in order to standardized the now fractured language, creating the MUMPS Users Group and MUMPS Development Committee. MUMPS MUMPS , or simply M, is a programming language to standardize interacting with the data. These efforts proved successful; a standard was complete by 1974, and by the early 1970s was in widespread use, often being locally data online solution storage.
