define record in computer

COBOL was the first widespread programming language to support record types,[8] and its record definition facilities were quite sophisticated at the time. The latter were provided eventually (by the typedef declaration), but the two concepts are still distinct in the language. It requires some degree of type polymorphism. These are slightly more complex than arrays as you can store more than one type of data together. If it is not indexed the entire employee file would have to be scanned to produce a listing of all employees in a specific department. Records are often called rows since each new record creates In computer programming language: Data structures …collection of data, and the record, a heterogeneous collection. It may contain the offsets of elements; the elements can therefore be stored in any order or may be omitted. The parameters of a function or procedure can often be viewed as the fields of a record variable; and the arguments passed to that function can be viewed as a record value that gets assigned to that variable at the time of the call. A record is a data structure that groups together related items of data. Each file is associated with a record variable where data is read into or written from. See our LP definition for additional information. These same possibilities apply to the comparison of two record values for equality. The crew is recording live in Los Angeles at the premiere of the new film. [ + of] The painting was … To capture audio or video from or within a particular location. Meaning of record for the defined word. A unique key is often called the primary key, or simply the record key. DNS records are stored in zone files and are used for translating domain names to IP addresses . It is a set of fields, like an employee’s job record as shown below. Other languages (such as COBOL) may match fields and values by their names, rather than positions. A record might store employee information—name, title, and salary. ... (Computer Science) computing a group of data or piece of information preserved as a unit in machine-readable form. A record with fields x, y, and z would thus belong to the type of records with fields x and y, as would a record with fields x, y, and r. The rationale is that passing an (x,y,z) record to a function that expects an (x,y) record as argument should work, since that function will find all the fields it requires within the record. Generally, a record was the smallest unit that could be read in from external storage (e.g. Records are distinguished from arrays by the fact that their number of fields is typically fixed, each field has a name, and that each field may have a different type. A collection of related data contained in one or more files or a database. Computer abbreviations, Database terms, File, Record Layout, Record length, Record Locking, Snapshot. [citation needed]. The organization of data in the record is usually prescribed by the programming language that defines the record's organization and/or by the application that processes it. Records are sometimes displayed or shared for reasons other than their original purpose. We had to record in my basement until we'd saved up enough money to start using a real studio. - 8318581 In computer science, a record is a basic data structure. Most languages allow assignment between records that have exactly the same record type (including same field types and names, in the same order). It's also a verb, more specifically, an intransitive verb and a transitive verb. The PL/I programming language provided for COBOL-style records. card reader, tape or disk). The … Indeed, in most object-oriented languages, records are just special cases of objects, and are known as plain old data structures (PODSs), to contrast with objects that use OO features. cords v. tr. a domain name to the IP address (Version 4) of the computer hosting the domain 3. 1) v. (rick-cored) to put a document into the official records of a county at the office of the County Recorder or Recorder of Deeds. The original Lisp programming language too was lacking records (except for the built-in cons cell), but its S-expressions provided an adequate surrogate. Some languages may implement a record as an array of addresses pointing to the fields (and, possibly, to their names and/or types). The following show examples of record definitions: Information block that is part of a database (data row), "Computer Science Dictionary Definitions", "Charles Babbage's Analytical Engine, 1838", "Automatic Computation: Charles Babbage and Computational Method", "EPICS Input / Output Controller (IOC) Application Developer's Guide", https://en.wikipedia.org/w/index.php?title=Record_(computer_science)&oldid=995234143, Articles with unsourced statements from May 2009, Creative Commons Attribution-ShareAlike License. Records were well established in the first half of the 20th century, when most data processing was done using punched cards. An example of record is to take the minutes of a staff meeting. A self-defining record is a type of record which contains information to identify the record type and to locate information within the record. Grammatically, this word "record" is a noun, more specifically, a countable noun. record in (something) 1. Most machine language implementations and early assembly languages did not have special syntax for records, but the concept was available (and extensively used) through the use of index registers, indirect addressing, and self-modifying code. record player n a device for reproducing the sounds stored on a record, consisting of a turntable, usually electrically driven, that rotates the record at a fixed speed of 33, 45, or (esp. As a result, the statements Y of Pts[3] := 7 and (Y of Pts)[3] := 7 would have the same effect. A record is simply a set of data stored in a table, for example, a customer record. Another example is a hospital or clinic with a medical record for you or a family member. You can think of a traditional database as an electronic filing system, organized by fields, records, and files.A field is a single piece of information; a record is one complete set of fields; … Record. ) Some languages may also allow order comparisons ('<'and '>'), using the lexicographic order based on the comparison of individual fields. How to use record in a sentence. Various tables hold various records in a database. A record is a database entry that may contain one or more values. See full dictionary entry for record COBUILD Advanced English Dictionary. In Algol 68, if Pts was an array of records, each with integer fields X and Y, one could write Y of Pts to obtain an array of integers, consisting of the Y fields of all the elements of Pts. , record information pronunciation, record Layout, record information translation, English dictionary contain records!
