In computer science, type conversion, [1] [2] type casting, [1] [3] type coercion, [3] and type juggling [4] [5] are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa.
For example, it is possible to convert Cyrillic text from KOI8-R to Windows-1251 using a lookup table between the two encodings, but the modern approach is to convert the KOI8-R file to Unicode first and from that to Windows-1251. This is a more manageable approach; rather than needing lookup tables for all possible pairs of character encodings ...
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Prior to the introduction of the desktop platform, it was known as SQL Server for Windows CE and SQL Server Mobile Edition. It includes both 32-bit and 64-bit native support. [1] SQL CE targets occasionally connected applications and applications with an embedded database. [2] It is free to download and redistribute. [2]
Maximum database size of 10 GB per database in SQL Server 2019, SQL Server 2017, SQL Server 2016, SQL Server 2014, SQL Server 2012, and 2008 R2 Express [7] (4 GB for SQL Server 2008 Express and earlier; compared to 2 GB in the former MSDE). The limit applies per database (log files excluded); but in some scenarios users can access more data ...
[10] [11] The tool can copy or move a package from a file into the server store, or back out again. Among a few other sundry functions, it can be used to delete, rename, encrypt, or decrypt packages. The Bulk Copy Program (BCP), is a command-line tool used to import or export data against a Microsoft SQL Server, [12] or Sybase database.
Windows 95, 98, ME have a 4 GB limit for all file sizes. Windows XP has a 16 TB limit for all file sizes. Windows 7 has a 16 TB limit for all file sizes. Windows 8, 10, and Server 2012 have a 256 TB limit for all file sizes. Linux. 32-bit kernel 2.4.x systems have a 2 TB limit for all file systems. 64-bit kernel 2.4.x systems have an 8 EB limit ...
While working at IBM he was involved in technical planning and design for the IBM products SQL/DS and DB2. He was also involved with Edgar F. Codd ’s relational model for database management. He left IBM in 1983 and has written extensively of the relational model, in association with Hugh Darwen .
