SQL CLR or SQLCLR SQL Common Language Runtime is technology for hosting of the Microsoft .NET common language runtime engine within SQL Server. The SQLCLR allows managed code to be hosted by, and run in, the Microsoft SQL Server environment. This technology, introduced in Microsoft SQL Server 2005, allow users for example to create the following types of managed code objects in SQL Server in .NET languages such as C Sharp programming language C or VB.NET . Stored procedure s SPs which are analogous to procedures or void functions in procedural languages like VB or C, Database trigger triggers which are stored procedures that fire in response to Data Manipulation Language DML or Data Definition Language DDL events, User defined function s UDFs which are analogous to functions in procedural languages, User defined aggregate s UDAs which allow developers to create custom aggregates that act on sets of data instead of one row at a time, User defined type s UDTs that allow users to create simple or complex data types which can be serialized and deserialized within the database. The SQL CLR relies on the creation, deployment, and registration of .NET assemblies , which are physically stored in managed code dynamic load libraries DLLs . These assemblies may contain .NET namespaces, classes, functions and properties.

PRTV Peterlee Relational Test Vehicle was the world s first relational database management system that could handle significant data volumes. It was a relational query system with powerful query facilities, but very limited update facility and no simultaneous multiuser facility.

MaxScript command processor is an interpreter that implements a subset of the Xbase xBase programming language especially conceived to be used inside web pages to provide server side scripting capabilities. MaxScript is not to be confused with MAXScript, the scripting language of the 3D animation package 3ds Max . As command processor MaxScript needs a web server to work with whenever the web server receives a request for a MaxScript page it must pass it to the interpreter, that parses all the lines, top to bottom, in search of xBase cod to be executed. Then the page is passed back to web server that deliveries it to web browser. MaxScript pages use the file extension .MSP MSP pages are standard HTML pages they can contain XHTML and Javascript code, as well as xBase code. xBase statements can consist on hundreds of lines or single function calls, always included into HTML server side tags. Tags for maxScript are similar to those used for PHP and other server side scripting languages to start xBase code into a web page the tag must be used. The tag marks the end of code. MaxScript is used as the core of freeware products like dbfree and in its commercial counterpart http www.dbmax.it DBMax The latest version 2.21 is dated 2008 and implements a large subset of xBase commands and functions, and the capability of writing UDFs User Defined Function to be integrated in the language. MaxScript was expressly designed to dynamically present live data on the internet and acts as a web server extension to process xBase Clipper code from inside an HTML page. As such the interpreter needs a web server to work with, and all the pages to be processed must reside on a web site accessible to it. The MaxScript Engine comes in form of a win32 executable and implements an xBase, Clipper like, programming language reach of features, commands and functions for any and all web application purposes, and uses built in drivers to dynamically access live data from DBF tables and present them ... more details
Multiple issues howto February 2011 notability February 2011 refimprove December 2009 A stored procedure is a subroutine available to applications accessing a relational database relational database management system database system . Stored procedures sometimes called a proc , sproc , StoPro , StoredProc , or SP are actually stored in the database data dictionary . Typical uses for stored procedures include data validation integrated into the database or access control mechanisms. Furthermore, stored procedures are used to consolidate and centralize logic that was originally implemented in applications. Extensive or complex processing that requires the execution of several SQL statements is moved into stored procedures, and all applications call the procedures. One can use nested stored procedures, by executing one stored procedure from within another. Stored procedures are similar to user defined function user defined functions UDFs . The major difference is that UDFs can be used like any other expression within SQL statements, whereas stored procedures must be invoked using the code CALL code statement. ref http publib.boulder.ibm.com infocenter iseries v5r3 index.jsp?topic db2 rbafzmstcallstmt.htm Call Procedure ref CALL procedure ... or EXECUTE procedure ... Stored procedures may return result set s, i.e. the results of a code SELECT code statement. Such result sets can be processed using cursor databases cursor s, by other stored procedures, by associating a result set locator, or by applications. Stored procedures may also contain declared variables for processing data and cursors that allow it to loop through multiple rows in a table. Stored procedure languages typically include code IF code , code WHILE code , code LOOP code , code REPEAT code , and code CASE code statements, and more. Stored procedures can receive variables, return results or modify variables and return them, depending on how and where the variable is declared. Implementation The exact and ... more details

The Windows NT startup process is the process by which Microsoft s Windows NT , Windows 2000 , Windows XP and Windows Server 2003 operating system s initialize. In Windows Vista and later, this process has changed slightly see Windows Vista startup process . Boot loader phase details NTLDR The boot loader phase varies by platform. Since the earlier phases are not specific to the OS, the boot process is considered to start For x86 architecture x86 or x86 64 x64 when the partition boot sector code is executed in real mode and loads NTLDR For IA 64 when the IA64ldr.efi Extensible Firmware Interface EFI program is executed later referred as simply IA64ldr From that point, the boot process continues as follows An NTLDR file, located in the root folder of the boot disk, is composed of two parts. The first is the StartUp module and immediately followed by the OS loader osloader.exe , both stored within that file. When NTLDR is loaded into memory and control is first passed to StartUp module, the CPU is operating in real mode . StartUp module s main task is to switch the processor into protected mode , which facilitates 32 bit memory access, thus allowing it to create the initial Interrupt descriptor table , Global Descriptor Table , page table s and enable paging . This provides the basic operating environment on which the operating system will build. StartUp module then loads and launches OS loader. NTLDR s OS loader includes basic functionality to access Advanced Technology Attachment IDE based disks formatted for NTFS or File Allocation Table FAT file systems, or CDFS ISO 9660 , ETFS or UDFS in newer operating system versions. Disks are accessed through the system INT 13 BIOS , through native ARC routines on Advanced RISC Computing ARC systems, or via network using Trivial File Transfer Protocol TFTP protocol. All BIOS calls are done through virtual 8086 mode beyond this point, as the BIOS can not be directly accessed within protected mode. If the boot disk is a SCSI di ... more details
