Term

Definition

Active Directory Service Interfaces (ADSI)

A service model and a set of COM interfaces that abstract the capabilities of directory services from different network directory providers (including Microsoft Active Directory) to present a single set of directory service interfaces for managing network resources.

Admin Base Objects (ABO)

A distributed COM (DCOM) object that implements the IMSAdminBase interface methods that enable an application to manipulate an IIS metabase.

Aspect-Oriented Programming (AOP)

A programming model that complements object-oriented or procedural programming by injecting new orthogonal capabilities into a library without physically integrating a great deal of cross-cutting code. Cross-cutting code is periodic code that deals with tangential issues outside of the main design purpose of the existing code, for example, security requirements, persistence, and contracts. Cross-cutting code is difficult to understand and maintain. Attributes in Microsoft's .NET Framework are an example of an implementation of AOP.

microdump

The smallest minidump files, which include very little information. For example, they might only contain information about a single thread, or information about modules that are actually referenced in the stack, or they might even include a truncated version of the stack.

minidump

User-mode dump files that include only selected parts of the memory associated with a process. The size and contents of a minidump file varies depending on the application being dumped and the application doing the dumping.

Simple Error Reporting

The standard type of error report created and reported to the Windows Quality Online Services (WinQual) portal by the operating system upon obtaining an unhandled exception from an application.

Simple Object Access Protocol (SOAP)

An open XML-based protocol for exchanging structured information on the Web. Although SOAP contains no application or transport semantics, it forms the foundation of a Web services stack, so that more abstract layers can be built on it, and it can run on top of many transports (although HTTP has become the preferred transport for most services).

Simple Service Discovery Protocol (SSDP)

A simple protocol for broadcasting and discovering small messages on a local subnet implemented as part of UPNP.
