PRC (Palm OS)
PRC (Palm Resource Code) is a Container format (computing), container format for code databases in Palm OS, Garnet OS and Access Linux Platform. Its structure is similar to PDB (Palm OS), PDB databases.N. Rhodes, J. McKeehan. Palm OS Programming, Second Edition, O'Reilly, 2001, . Usually, a PRC file is a flat representation of a Palm OS application that is stored as forked database on the PDA. PRC files are also used by the Mobipocket e-book-reader (here sometimes referred to as MOBI formatMobileRead WikiReference for the MOBI format/ref>). The Kindle File Format, AZW format of Amazon Kindle, Amazon's Kindle reading device is in turn a Digital rights management, DRM-restricted form of the Mobipocket format. On Palm OS, PRC files are used for applications, localized resources (overlays) and shared libraries. Structure of PRC file In its essence, a PRC file is similar to a classic Mac OS application. It contains a PRC header, PRC resource headers and PRC resources.Theodore Ts'o (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Container Format (computing)
A container format (informally, sometimes called a wrapper) or metafile is a file format that allows multiple data streams to be embedded into a single file, usually along with metadata for identifying and further detailing those streams. Notable examples of container formats include archive files (such as the ZIP format) and formats used for multimedia playback (such as Matroska, MP4, and AVI). Among the earliest cross-platform container formats were Distinguished Encoding Rules and the 1985 Interchange File Format. Design Although containers may identify how data or metadata is encoded, they do not actually provide instructions about how to decode that data. A program that can open a container must also use an appropriate codec to decode its contents. If the program doesn't have the required algorithm, it can't use the contained data. In these cases, programs usually emit an error message that complains of a missing codec, which users may be able to acquire. Container ...

Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm OS
Palm OS (also known as Garnet OS) was a mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It is provided with a suite of basic applications for personal information management. Later versions of the OS have been extended to support smartphones. Several other licensees have manufactured devices powered by Palm OS. Following Palm's purchase of the Palm trademark, the currently licensed version from ACCESS was renamed ''Garnet OS''. In 2007, ACCESS introduced the successor to Garnet OS, called Access Linux Platform; additionally, in 2009, the main licensee of Palm OS, Palm, Inc., switched from Palm OS to webOS for their forthcoming devices. Creator and ownership Palm OS was originally developed under the direction of Jeff Hawkins at Palm Computing, Inc. Palm was later acquired by U.S. Robotics Corp., which in turn was later bought by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
