Persistent Data
Persistent data in the field of data processing denotes information that is infrequently accessed and unlikely to be modified. Static data is information, for example a record, that does not change and may be intended to be permanent. It may have previously been categorized as persistent or dynamic. Dynamic data (also known as transactional data) is information that is asynchronously updated as new information becomes available. Updates to dynamic data may come at any time, with periods of inactivity in between.

Data Processing
Data processing is the collection and manipulation of digital data to produce meaningful information. Data processing is a form of ''information processing'', which is the modification (processing) of information in any manner detectable by an observer.Data processing is distinct from '' word processing'', which is manipulation of text specifically rather than data generally. Functions Data processing may involve various processes, including: * Validation – Ensuring that supplied data is correct and relevant. * Sorting – "arranging items in some sequence and/or in different sets." * Summarization (statistical) or (automatic) – reducing detailed data to its main points. * Aggregation – combining multiple pieces of data. * Analysis – the "collection, organization An organization or organisation (English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-ise, -ize (-isation, -izat ...

Data Record
In a relational database, a row or " record" or "tuple", represents a single, implicitly structured data item in a table. A database table can be thought of as consisting of rows and columns. Cory Janssen, Techopedia, retrieved 27 June 2014 Each row in a table represents a set of related data, and every row in the table has the same structure. For example, in a table that represents companies, each row might represent a single company. Columns might represent things like company name, address, etc. In a table that represents ''the association'' of employees with departments, each row would associate one employee with one department. The implicit structure of a row, and the meaning of the data values in a row, requires that the row be understood as providing a succession of data values, one in each column ...

Dynamic Data
In data management, dynamic data or transactional data is information that is periodically updated, meaning it changes asynchronously over time as new information becomes available. The concept is important in data management, since the time scale of the data determines how it is processed and stored. Data that is not dynamic is considered either static (unchanging) or persistent, which is data that is infrequently accessed and not likely to be modified. Dynamic data is also different from streaming data, which is a constant flow of information. Dynamic data may be updated at any time, with periods of inactivity in between. Examples In enterprise data management, dynamic data is likely to be transactional, but it is not limited to financial or business transactions. It may also include engineering transactions, such as a revised schematic diagram A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols ...

JBND
JBND is a pure Java library made to ease the creation of programs that present data stored in persistent sources to end users. It was created at first to streamline making Java Client applications for the WebObjects platform (by Apple Inc.), for which the GUI is written in Swing. However, JBND's architecture allows the expansion of the library to include other UI systems, as well as other persistence stores. Currently, JBND comes with full support for connecting Enterprise Objects Frameworks (the data layer of WebObjects) and Swing user interfaces. See also *Java * GUI * Swing *WebObjects WebObjects is a discontinued Java web application server and a server-based web application framework originally developed by NeXT Software, Inc.

Persistent Data Structure
In computing, a persistent data structure or not ephemeral data structure is a data structure that always preserves the previous version of itself when it is modified. Such data structures are effectively immutable, as their operations do not (visibly) update the structure in-place, but instead always yield a new updated structure. The term was introduced in Driscoll, Sarnak, Sleator, and Tarjan's 1986 article. A data structure is partially persistent if all versions can be accessed but only the newest version can be modified. The data structure is fully persistent if every version can be both accessed and modified. If there is also a meld or merge operation that can create a new version from two previous versions, the data structure is called confluently persistent. Structures that are not persistent are called ''ephemeral''. These types of data structures are particularly common in logical and functional programming, as languages in those paradigms discourage (or fully forbid) ...

Phantom OS
Phantom OS is an Persistence_(computer_science)#Orthogonal_or_transparent_persistence, orthogonally persistent managed code general-purpose operating system. It is based on a concept of persistent virtual memory, and executes bytecode in a virtual machine. It is one of a few OSes not based on the classic concepts of Unix-like systems. Phantom is based on the principle that "Everything is an Object (computer science), object", in contrast to the Unix-like approach of "Everything is a file". Overview Phantom was founded by and is being developed mostly by Russian programmers. It is free and open-source software (FOSS) released under a GNU Lesser General Public License (LGPL). Basics Managed code – Memory protection on object level, rather than Process (computing), process level; absence of pointer arithmetic in managed code avoids many problems that exist and occur in unmanaged code. Global address space – Inexpensive inter-process communication (IPC). Single address space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
