Programming: Pair Programming (Definitions)

"An XP practice requiring that each piece of source code to be integrated into the software product should be created by two programmers jointly at one computer."" (Johannes Link & Peter Fröhlich, "Unit Testing in Java", 2003)

"A coding technique where one programmer (the driver) writes code and explains what he or she is doing, while another watches and looks for problems." (Rod Stephens, "Start Here!™ Fundamentals of Microsoft® .NET Programming", 2011)

"A software development approach whereby lines of code (production and/or test) of a component are written by two programmers sitting at a single computer. This implicitly means ongoing real-time code reviews are performed." (IQBBA, "Standard glossary of terms used in Software Engineering", 2011)

"An Extreme Programming practice where two (or three) programmers work together at the same computer. The driver or pilot types while the observer, navigator, or pointer watches and reviews each line of code as it is typed." (Rod Stephens, "Beginning Software Engineering", 2015)

"A software development approach whereby lines of code (production and/or test) of a component are written by two programmers sitting at a single computer. This implicitly means ongoing real-time code reviews are performed." (SQA)

Programming: BLOB (Definitions)

"A type of data column containing binary data such as graphics, sound, or compiled code. This is a general term for text or image data type. BLOBs are not stored in the table rows themselves, but in separate pages referenced by a pointer in the row." (Microsoft Corporation, "SQL Server 7.0 System Administration Training Kit", 1999)

"BLOB is a data type for fields containing large binary data such as images." (S. Sumathi & S. Esakkirajan, "Fundamentals of Relational Database Management Systems", 2007)

"A binary large object. Large value data types [varchar(max), nvarchar(max), and varbinary(max)] are stored as BLOBs. Within SQL Server 2005, BLOBs can be as large as 2GB." (Darril Gibson, "MCITP SQL Server 2005 Database Developer All-in-One Exam Guide", 2008)

"A data type that can hold large objects of arbitrary content such as video files, audio files, images, and so forth. Because the data can be any arbitrary chunk of binary data, the database does not understand its contents so you cannot search in these fields." (Rod Stephens, "Beginning Database Design Solutions", 2008)

"Binary large object (BLOB) data is data that is stored using the varbinary(max) data type. A BLOB column or variable can hold up to 2.1 GB of data, as opposed to a regular non-LOB varbinary or binary column or variable, which can max out at 8,000 bytes of data." (Michael Coles & Rodney Landrum, , "Expert SQL Server 2008 Encryption", 2008)

"Very large binary representation of multimedia objects that can be stored and used in some enhanced relational databases." (Paulraj Ponniah, "Data Warehousing Fundamentals for IT Professionals", 2010)

"A discrete packet of binary data that has an exceptionally large size, such as pictures or audio tracks stored as digital data, or any variable or table column large enough to hold such values. The designation 'binary large object' typically refers to a packet of data that is stored in a database and is treated as a sequence of uninterpreted bytes." (Microsoft, "SQL Server 2012 Glossary", 2012)

"A large assemblage of binary data (e.g., images, movies, multimedia files, even collections of executable binary code) that are associated with a common group identifier and that can, in theory, be moved (from computer to computer) or searched as a singled data object. Traditional databases do not easily handle BLOBs." (Jules H Berman, "Principles of Big Data: Preparing, Sharing, and Analyzing Complex Information", 2013)

"A blob is any resource whose internal structure is functionally opaque for the purpose at hand." (Robert J Glushko, "The Discipline of Organizing: Professional Edition" 4th Ed., 2016)

Programming: Block (Definitions)

"A series of statements enclosed by BEGIN and END. Blocks define which set of statements will be affected by control-of-flow language such as IF or WHILE. You can nest BEGIN...END blocks within other BEGIN... END blocks." (Microsoft Corporation, "SQL Server 7.0 System Administration Training Kit", 1999)

"A section of code grouped together by braces that sets apart a section of code in a smaller area than a full procedure. A procedure might contain several blocks of code." (Greg Perry, "Sams Teach Yourself Beginning Programming in 24 Hours 2nd Ed.", 2001)

"A sequence of PL/SQL code, beginning with DECLARE or BEGIN and ending with END. The block is a core organizational unit of PL/SQL programming. See Chapter 2 for a thorough discussion." (Bill Pribyl & Steven Feuerstein, "Learning Oracle PL/SQL", 2001)

"A series of Transact-SQL statements enclosed by BEGIN and END. You can nest BEGIN...END blocks within other BEGIN...END blocks." (Anthony Sequeira & Brian Alderman, "The SQL Server 2000 Book", 2003)

"A syntactic construct consisting of a sequence of Perl statements that is delimited by braces. The if and while statements are defined in terms of BLOCKs, for instance. Sometimes we also say 'block' to mean a lexical scope; that is, a sequence of statements that acts like a BLOCK, such as within an eval or a file, even though the statements aren’t delimited by braces." (Jon Orwant et al, "Programming Perl" 4th Ed., 2012)

"A Transact-SQL statement enclosed by BEGIN and END." (Microsoft, "SQL Server 2012 Glossary", 2012)

"The information stored in a sector" (Nell Dale & John Lewis, "Computer Science Illuminated" 6th Ed., 2015)

"A set of rows retrieved from a database server that are transmitted as a single result set to satisfy a cursor FETCH request." (Sybase, "Open Server Server-Library/C Reference Manual", 2019)
