Muenchian Grouping
Muenchian grouping (or ''Muenchian method'', named after Steve Muench) is an algorithm for grouping of data used in XSLT, XSL Transformations v1 that identifies keys in the results and then queries all nodes with that key. This improves the traditional alternative for grouping, whereby each node is checked against previous (or following) nodes to determine if the key is unique (if it is, this would indicate a new group). In both cases the key can take the form of an attribute, element, or computed value. The unique identifier is referred to as a key because of the use of the 'key' function to identify and track the group variable. The technique is not necessary in XSLT 2.0+, which introduces the new for-each-group tag. General aspect of the transform The method took advantage of XSLT's ability to index documents using a key. The trick involves using the index to efficiently figure out the set of unique grouping keys and then using this set to process all nodes in the group: ...

XSLT En
XSLT (Extensible Stylesheet Language Transformations) is a language originally designed for XML transformation language, transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text or XSL Formatting Objects, which may subsequently be converted to other formats, such as Portable Document Format, PDF, PostScript and Portable Network Graphics, PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification. As of August 2022, the most recent stable version of the language is XSLT 3.0, which achieved Recommendation status in June 2017. XSLT 3.0 implementations support Java, .NET, C/C++, Python, PHP and NodeJS. An XSLT 3.0 Javascript library can also be hosted within the Web Browser. Modern web browsers also include native support for XSLT 1.0. For an XSLT document transformation, the original document is not changed; rather, a new document is created based on the content of an existing one. T ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a Heuristic (computer science), heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. ...
