In computing, Microsoft's ActiveX Data Objects (ADO) comprises a set of Component Object Model (COM) objects for accessing data sources. A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner).
The corresponding SQL Server data type is binary, with only two states; the permissible values are 0 and 1. Date/Time (Extended): SQL Server's smalldatetime format has precision of 1 minute, minimum date value is 1900-01-01, maximum date value is 2079-06-06; datetime format has precision of 10/3 milliseconds (rounded to increments of .000, .003 ...
Jet, being part of a relational database management system (RDBMS), allows the manipulation of relational databases. [1] It offers a single interface that other software can use to access Microsoft databases and provides support for security, referential integrity, transaction processing, indexing, record and page locking, and data replication.
The reserved field is skipped. The family field comes directly after the first dot, so in this case 0d (13 in decimal) for DDS (Data Distribution Service). The remaining parts, each separated with a dot, are the node bytes. The lowercase form of the hexadecimal values is the generally preferred format.

The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running.
In some programming languages, a similar notation now called sigils is built into the language and enforced by the compiler. For example, in some forms of BASIC, name$ names a string and count% names an integer. The major difference between Hungarian notation and sigils is that sigils declare the type of the variable in the language, whereas ...
There are three reasons for the atomicity requirements. First, a reference count field may be updated by multiple threads, and so an adequate atomic instruction, such as a (costly) compare-and-swap, must be used to update the counts. Second, it must be clear which object loses a reference so that its reference count can be adequately decremented.
