The EXCEPT ALL operator does not remove duplicates, but if a row appears X times in the first query and Y times in the second, it will appear (,) times in the result set. Notably, the Oracle platform provides a MINUS operator which is functionally equivalent to the SQL standard EXCEPT DISTINCT operator.
A model contains one or more entities, and entities contain members that are the data records. An entity is similar to a table. Like other MDM products, Master Data Services aims to create a centralized data source and keep it synchronized, and thus reduce redundancies, across the applications which process the data.

List of applications and frameworks that use skip lists: Apache Portable Runtime implements skip lists. [9] MemSQL uses lock-free skip lists as its prime indexing structure for its database technology. MuQSS, for the Linux kernel, is a CPU scheduler built on skip lists. [10] [11] Cyrus IMAP server offers a "skiplist" backend DB implementation [12]
Joining data from multiple sources (e.g., lookup, merge) and deduplicating the data; Aggregating (for example, rollup – summarizing multiple rows of data – total sales for each store, and for each region, etc.) Generating surrogate-key values; Transposing or pivoting (turning multiple columns into multiple rows or vice versa)
Also included is SharePoint Server 2007, a major revision to the server platform for Office applications, which supports Excel Services, a client-server architecture for supporting Excel workbooks that are shared in real time between multiple machines, and are also viewable and editable through a web page.
Doing this breaks the list into multiple lists, defeating the purpose of using list markup. This adversely affects accessibility (screen readers will tell the visually impaired user there are multiple lists), [1] and interferes with machine-parseability of the content for reuse. Moreover, in certain Web browsers, the extra white-space between ...
When personal computers were initially released in the 1970s and 1980s, they typically included a version of BASIC so that customers could write their own programs. . Microsoft's first products were BASIC compilers and interpreters, and the company distributed versions of BASIC with MS-DOS (versions 1.0 through 6.0) and developed follow-on products that offered more features and capabilities ...
Two code sequences may be duplicates of each other without being character-for-character identical, for example by being character-for-character identical only when white space characters and comments are ignored, or by being token-for-token identical, or token-for-token identical with occasional variation. Even code sequences that are only ...
