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. In systems with record subtyping, operations on values of record type may also include: In such settings, a specific record type implies that a specific set of fields are present, but values of that type may contain additional fields. Many ways of practically implementing records in programming languages would have trouble with allowing such variability, but the matter is a central characteristic of record types in more theoretical contexts. Groups of records are stored in a table, which defines what types of data each record may contain. 3. A record may refer to any of the following: 1. A record … A record is a value that contains other values, typically in fixed number and sequence and typically indexed by names. A record is simply a set of data stored in a table, for example, a customer record. Records are composed of fields, each of which contains one item of information. Records in a database or spreadsheet are usually called " rows ". 13. A new record produces a new row in the table that’s why records are oftentimes labeled as rows. An example of record is for a parent to use a video camera to document his son's first birthday party. The original machine-readable medium used for data (as opposed to control) was punch card used for records in the 1890 United States Census: each punch card was a single record. This page was last edited on 19 December 2020, at 23:03. 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. (in some computer languages) a data structure designed to allow the handling of groups of … The definition includes specifying the data type of each field and an identifier (name or label) by which it can be accessed. Meaning of record for the defined word. If there are domain name aliases, such as the commonly used "www" preceding the domain name, these will also be listed in the DNS record. MX record (Mail Exchange record): An MX record (Mail Exchange record) is a domain name system ( DNS ) server record that contains information about which mail server the … 2. record information synonyms, record information pronunciation, record information translation, English dictionary definition of record information. A personnel record might contain a name, a salary, and a rank. If you keep information on record, you write it down or store it in a computer so that it can be used later. Records in a database or spreadsheet are usually called "rows".[1][2][3][4]. Record definition is - to set down in writing : furnish written evidence of. The representation of records in memory varies depending on the programming languages. 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 record type is a data type that describes such values and variables. Record is defined as to register in a permanent form for playback or to make a permanent file of something. Some languages may also allow order comparisons ('<'and '>'), using the lexicographic order based on the comparison of individual fields. The PL/I programming language provided for COBOL-style records. a domain name to the IP address (Version 4) of the computer hosting the domain In the same vein, a record type can be viewed as the computer language analog of the Cartesian product of two or more mathematical sets, or the implementation of an abstract product type in a specific language. From The Collaborative International Dictionary of English v.0.48 [gcide]: Record \ Re * … Also, in the call stack that is often used to implement procedure calls, each entry is an activation record or call frame, containing the procedure parameters and local variables, the return address, and other internal fields. Most languages allow assignment between records that have exactly the same record type (including same field types and names, in the same order). A self-defining record is a type of record which contains information to identify the record type and to locate information within the record. Record (Computer Science Definition) - Computing Students. Since type-theoretical records may contain first-class function-typed fields in addition to data, they can express many features of object-oriented programming. Compare the journal entry from 1880 and the punch card from 1895. Declaration of a new record type, including the position, type, and (possibly) name of each field; Declaration of variables and values as having a given record type; Construction of a record value from given field values and (sometimes) with given field names; Selection of a field of a record with an explicit name; Assignment of a record value to a record variable; Adding a new field to a record, setting the value of the new field. WhatIs.com. A record is the best result that has ever been achieved in a particular sport or activity, for example the fastest time, the furthest distance, or the greatest number of victories. A collection of related data contained in one or more files or a database. A database, often abbreviated as DB, is a collection of information organized in such a way that a computer program can quickly select desired pieces of data.. Fields, Records and Files. It is a set of fields, like an employee’s job record as shown below. Record (computer science), a data structure Record, or row (database), a set of fields in a database related to one entity; Boot sector or boot record, record used to start an operating system; Storage record, a basic input/output structure; Documents. 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. A record is a database entry that may contain one or more values. To capture audio or video from or within a particular location. An object in object-oriented language is essentially a record that contains procedures specialized to handle that record; and object types are an elaboration of record types. In type theory, product types (with no field names) are generally preferred due to their simplicity, but proper record types are studied in languages such as System F-sub. Request an Addition. See our LP definition for additional information. Other languages may be more flexible in this regard, and require only that each value field can be legally assigned to the corresponding variable field; so that, for example, a short integer field can be assigned to a long integer field, or vice versa. The crew is recording live in Los Angeles at the premiere of the new film. 2. We had to record in my basement until we'd saved up enough money to start using a real studio. In relational databases, a record is a group of related data held within the same structure. The modern notion of records in computer science, with fields of well-defined type and size, was already implicit in 19th century mechanical calculators, such as Babbage's Analytical Engine.[6][7]. Some languages may also allow assignment between records whose fields have different names, matching each field value with the corresponding field variable by their positions within the record; so that, for example, a complex number with fields called real and imag can be assigned to a 2D point record variable with fields X and Y. Depending on the storage medium and file organization the employee number might be indexed—that is also stored in a separate file to make lookup faster. Generally, a record was the smallest unit that could be read in from external storage (e.g. A record may refer to any of the following: 1. Separate fields are referred to as columns be… In the Pascal programming language, the command with R do S would execute the command sequence S as if all the fields of record R had been declared as variables. A unique key is often called the primary key, or simply the record key. How to use record in a sentence. For example, your computer manufacturer may have a record on you or your computer, this record may contain the history of your computer(s). A record in a database is an object that can have one or more values. Most modern computer languages allow the programmer to define new record types. formerly) 78 revolutions a minute. [5] The fields of a record may also be called members, particularly in object-oriented programming; fields may also be called elements, though this risks confusion with the elements of a collection. Record (computer science) In computer science, a record (also called a structure, struct, or compound data) is a basic data structure. The original Lisp programming language too was lacking records (except for the built-in cons cell), but its S-expressions provided an adequate surrogate. These are slightly more complex than arrays as you can store more than one type of data together. Definition of record : anything (such as a document or a phonograph record or a photograph) providing permanent evidence of or information about past events - sound recording consisting of a disk with a continuous groove; used to reproduce music by rotating while a phonograph needle tracks in the groove - the number of wins versus losses and ties a team has had In computer programming language: Data structures …collection of data, and the record, a heterogeneous collection. (1) In database management systems, a complete set of information. In computer science, a record (also called a structure, struct, or compound data) is a basic data structure. Typically each record of a data file would be recorded in one punched card, with specific columns assigned to specific fields. Databases may contain multiple tables which may each contain multiple records. DNS records are stored in zone files and are used for translating domain names to IP addresses . For example, with a … record definition: 1. to store sounds or moving pictures using electronic equipment so that they can be heard or seen…. In this alternative, the two operands are still required to have the same sequence of field types. Grammatically, this word "record" is a noun, more specifically, a countable noun. A record is a data structure that groups together related items of data. It is designed to execute applications and provides a variety of solutions by combining integrated hardware and software components. Various tables hold various records in a database. See full dictionary entry for record COBUILD Advanced English Dictionary. Record. ) To make an audio or video recording from or within a particular location. Some languages may provide facilities that enumerate all fields of a record, or at least the fields that are references. 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; … The practice is to keep on record any analysis of samples. The Pascal programming language was one of the first languages to fully integrate record types with other basic types into a logically consistent type system. It may contain the offsets of elements; the elements can therefore be stored in any order or may be omitted. Learn more. computing a group of data or piece of information preserved as a unit in machine-readable form. 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. A key is a field or set of fields in the record that serves as an identifier. Computer: A computer is a machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program. An example of record is to take the minutes of a staff meeting. [ + of] The painting was … Depending on the language, however, two record data types defined separately may be regarded as distinct types even if they have exactly the same fields. 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. The latter were provided eventually (by the typedef declaration), but the two concepts are still distinct in the language. 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. The early languages developed for numeric computing, such as FORTRAN (up to FORTRAN IV) and Algol 60, did not have support for record types; but later versions of those languages, such as Fortran 77 and Algol 68 did add them. record noun (INFORMATION) B2 [ C or U ] a piece of information or a description of an event that is written on paper or stored on a computer: The weather center keeps a record of the weather. This may result in two or more fields stored into the same word of memory; indeed, this feature is often used in systems programming to access specific bits of a word. record in (something) 1. For example, your computer manufacturer may have a record on you or your computer, this record may contain the history of your computer (s). Business record, of economic … For example, a date could be stored as a record containing a numeric year field, a month field represented as a string, and a numeric day-of-month field. For example, when the United States wrote a check to Russia to purchase Alaska in 1867, the cancelled check became proof of America’s purchase (original use). Records can exist in any storage medium, including main memory and mass storage devices such as magnetic tapes or hard disks. On the other hand, most compilers will add padding fields, mostly invisible to the programmer, in order to comply with alignment constraints imposed by the machine—say, that a floating point field must occupy a single word. card reader, tape or disk). The salary field would not normally be considered usable as a key. Objects in object-oriented languages are often implemented in rather complicated ways, especially in languages that allow multiple class inheritance. As a result, the statements Y of Pts[3] := 7 and (Y of Pts)[3] := 7 would have the same effect. For example an employee file might contain employee number, name, department, and salary. More specifically, a record is a grouping of fields within a table that reference one particular object. Record, a document for administrative use . The C programming language initially provided the record concept as a kind of template (struct) that could be laid on top of a memory area, rather than a true record data type. Sometimes abbreviated as REC, record is a function that records audio from a microphone or another source. Define record information. Computer abbreviations, Database terms, File, Record Layout, Record length, Record Locking, Snapshot. All forms of information registered in either temporary or permanent form so that it can be retrieved, reproduced, or preserved. These same possibilities apply to the comparison of two record values for equality. 1) In computer data processing, a record is a collection of data items arranged for processing by a program. Many computer files are organized as arrays of logical records, often grouped into larger physical records or blocks for efficiency. Records are often called rows since each new record creates record. An Electronic Record is defined by Part 11 as “any combination of text, graphics, data, audio, pictorial, or other information representation in digital form that is created, modified, maintained, archived, retrieved, or distributed by a computer system.” This definition ensures that electronic records are the same as paper records. The concept of records and fields was central in some early file sorting and tabulating utilities, such as IBM's Report Program Generator (RPG). The language allows for the definition of nested records with alphanumeric, integer, and fractional fields of arbitrary size and precision, as well as fields that automatically format any value assigned to them (e.g., insertion of currency signs, decimal points, and digit group separators). A record is a collection of fields, possibly of different data types, typically in a fixed number and sequence. This facility is needed to implement certain services such as debuggers, garbage collectors, and serialization. It requires some degree of type polymorphism. 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. means a record kept in a form which is readable by means of a computer; The employee number will be unique in the organization and would be the primary key. In computer science, records (also called tuples, structs, or compound data) are among the simplest data structures. A collection of related data contained in one or more files or a database. Define computer record. A record might store employee information—name, title, and salary. The process is that the document is taken or sent to the Recorder's office, a recording fee paid, the document is given a number (a document number, volume or reel number and page number), stamped with the date (and usually the time) of … 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. PL/I allows both of the preceding types of assignment, and also allows structure expressions, such as a = a+1; where "a" is a record, or structure in PL/I terminology. COBOL also provides a MOVE CORRESPONDING statement that assigns corresponding fields of two records according to their names. Records were well established in the first half of the 20th century, when most data processing was done using punched cards. 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. A record can be viewed as the computer analog of a mathematical tuple, although a tuple may or may not be considered a record, and vice versa, depending on conventions and the specific programming language. The definition of record in Dictionary is as: An item of information put into a temporary or permanent physical medium. An item or collection of data Computing. The concept of record can be traced to various types of tables and ledgers used in accounting since remote times. Arecord is a collection of fields, possibly of different data types, typically in fixed number and sequence. Some early computers, such as the IBM 1620, had hardware support for delimiting records and fields, and special instructions for copying such records. A record in a database is an object that can contain one or more values. So, instead of writing Pt.X := 5; Pt.Y := Pt.X + 3 one could write with Pt do begin X := 5; Y := X + 3 end. Some languages may implement a record as an array of addresses pointing to the fields (and, possibly, to their names and/or types). The selection of a field from a record value yields a value. For example, someone may record an MP3 to a CD, so they can listen to it when away from their computer. Usually the fields are stored in consecutive positions in memory, in the same order as they are declared in the record type. A record is a collection of fields, possibly of different data types, typically in a fixed number and sequence. How to define the word record? The … Define Record ????? Multiple records are contained in a file or data set. Most languages designed after Pascal (such as Ada, Modula, and Java) also supported records. Some languages may also require that corresponding types have the same size and encoding as well, so that the whole record can be assigned as an uninterpreted bit string. He set the world record of 12.92 seconds. Indexing is one factor considered when designing a file. Each file is associated with a record variable where data is read into or written from. A record is a group of data saved in a table. Another example is a hospital or clinic with a medical record for you or a family member. An LP is a 12-inch vinyl disc used in record players. - 8318581 In computer science, a record is a basic data structure. Records are sometimes displayed or shared for reasons other than their original purpose. An array may represent a vector of numbers, a list of strings, or a collection of vectors (an array of arrays, or mathematical matrix). The department code may not be unique; it may also be indexed, in which case it would be considered a secondary key, or alternate key. It's also a verb, more specifically, an intransitive verb and a transitive verb. COBOL was the first widespread programming language to support record types,[8] and its record definition facilities were quite sophisticated at the time. cords v. tr. A record may have zero or more keys. A Circle record might contain a center and a radius—in this instance, the center itself might be represented as a point record containing x and y coordinates. 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. A set of records constitutes a file. 1. Other languages (such as COBOL) may match fields and values by their names, rather than positions. {To record a deed }, { mortgage }, { lease }, etc., to have a copy of the same entered in the records of the office designated by law, for the information of the public. [citation needed]. Records are a fundamental component of most data structures, especially linked data structures. They also contain other data, including the domain name's name server and mail server information. ... (Computer Science) computing a group of data or piece of information preserved as a unit in machine-readable form. The term record is frequently used synonymously with row.
