Transformation Languages
A transformation language is a computer language designed to transform some input text in a certain formal language into a modified output text that meets some specific goal. Program transformation systems such as Stratego/XT, TXL (programming language), TXL, Tom (pattern matching language), Tom, DMS Software Reengineering Toolkit, DMS, and ASF+SDF Meta Environment, ASF+SDF all have transformation languages as a major component. The transformation languages for these systems are driven by declarative descriptions of the structure of the input text (typically a grammar), allowing them to be applied to wide variety of formal languages and documents. Macro (computer science), Macro languages are a kind of transformation languages to transform a meta language into specific higher programming language like Java (programming language), Java, C++, Fortran or into lower-level Assembly language. In the model-driven engineering technical space, there are model transformation languages (MTL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Language
A computer language is a formal language used to communicate with a computer. Types of computer languages include: * Software construction#Construction languages, Construction language – all forms of communication by which a human can Computer programming, specify an executable problem solution to a computer ** Command language – a language used to control the tasks of the computer itself, such as starting programs ** Configuration file#Configuration languages, Configuration language – a language used to write configuration files ** Programming language – a formal language designed to communicate instructions to a machine, particularly a computer ***Scripting language – a type of programming language which typically is interpreted at runtime rather than being compiled ** Query language – a language used to make Information retrieval, queries in databases and information systems ** Transformation language – designed to transform some input te ...

Tritium (programming Language)
Tritium is a simple scripting language for efficiently transforming structured data like HTML, XML, and JSON. It is similar in purpose to XSLT but has a syntax influenced by jQuery, Sass, and CSS versus XSLT's XML based syntax. History Tritium was designed by Hampton Catlin, the creator of languages Sass and Haml and is currently bundled with the Moovweb mobile platform. As with Sass (created to address deficiencies in CSS) and Haml (created to address deficiencies in coding HTML templates), Catlin designed Tritium to address issues he saw with XSLT while preserving the core benefits of a transformation language. Much of this was based on his prior experience porting Wikipedia's desktop website to the mobile web. Open Tritium is the open source implementation of the Tritium language. It was presented at O'Reilly Open Source Convention 2014 and the compiler is implemented in Go. Concept Tritium takes as input HTML, XML, or JSON documents and outputs HTML, XML, or JS ...

Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Data Transformation
In computing, data transformation is the process of converting data from one format or structure into another format or structure. It is a fundamental aspect of most data integrationCIO.com. Agile Comes to Data Integration. Retrieved from: https://www.cio.com/article/2378615/data-management/agile-comes-to-data-integration.html and data management tasks such as data wrangling, data warehousing, data integration and application integration. Data transformation can be simple or complex based on the required changes to the data between the source (initial) data and the target (final) data. Data transformation is typically performed via a mixture of manual and automated steps.DataXFormer. Morcos, Abedjan, Ilyas, Ouzzani, Papotti, Stonebraker. An interactive data transformation tool.

Data Migration
Data migration is the process of selecting, preparing, extracting, and transforming data and permanently transferring it from one computer storage system to another. Additionally, the validation of migrated data for completeness and the decommissioning of legacy data storage are considered part of the entire data migration process. Data migration is a key consideration for any system implementation, upgrade, or consolidation, and it is typically performed in such a way as to be as automated as possible, freeing up human resources from tedious tasks. Data migration occurs for a variety of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation, disaster recovery, and data center relocation. The standard phases , "nearly 40 percent of data migration projects were over time, over budget, or failed entirely." Thus, proper planning is critical for an effective data migration.

Data Mapping
In computing and data management, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks, including: * Data transformation or data mediation between a data source and a destination * Identification of data relationships as part of data lineage analysis * Discovery of hidden sensitive data such as the last four digits of a social security number hidden in another user id as part of a data masking or de-identification project * Consolidation of multiple databases into a single database and identifying redundant columns of data for consolidation or elimination For example, a company that would like to transmit and receive purchases and invoices with other companies might use data mapping to create data maps from a company's data to standardized ANSI ASC X12 messages for items such as purchase orders and invoices. Standards X12 standards are generic E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Element
In metadata, the term data element is an atomic unit of data that has precise meaning or precise semantics. A data element has: # An identification such as a data element name # A clear data element definition # One or more representation terms # Optional enumerated values Code (metadata) # A list of synonyms to data elements in other metadata registries Synonym ring Data elements usage can be discovered by inspection of software applications or application data files through a process of manual or automated Application Discovery and Understanding. Once data elements are discovered they can be registered in a metadata registry. In telecommunications, the term data element has the following components: #A named unit of data that, in some contexts, is considered indivisible and in other contexts may consist of data items. #A named identifier of each of the entities and their attributes that are represented in a database. #A basic unit of information built on standard stru ...

Data Conversion
Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks. Similarly, the operating system is predicated on certain standards for data and file handling. Furthermore, each computer program handles data in a different manner. Whenever any one of these variables is changed, data must be converted in some way before it can be used by a different computer, operating system or program. Even different versions of these elements usually involve different data structures. For example, the changing of bits from one format to another, usually for the purpose of application interoperability or of the capability of using new features, is merely a data conversion. Data conversions may be as simple as the conversion of a text file from one character encoding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bidirectional Transformation
In computer programming, bidirectional transformations (bx) are programs in which a single piece of code can be run in several ways, such that the same data are sometimes considered as input, and sometimes as output. For example, a bx run in the forward direction might transform input I into output O, while the same bx run backward would take as input versions of I and O and produce a new version of I as its output. Model transformation#Unidirectional versus bidirectional, Bidirectional model transformations are an important special case in which a model is input to such a program. Some bidirectional languages are Bijection, ''bijective''. The bijectivity of a language is a severe restriction of its power, because a bijective language is merely relating two different ways to present the very same information. More general is a lens language, in which there is a distinguished forward direction ("get") that takes a concrete input to an abstract output, discarding some information i ...

XMLambda
An XML transformation language is a programming language designed specifically to transform an ''input'' XML document into an ''output'' document which satisfies some specific goal. There are two special cases of transformation: * XML to XML: the ''output document'' is an XML document. * XML to Data: the ''output document'' is a byte stream. XML to XML As XML to XML transformation outputs an XML document, XML to XML transformation chains form XML pipelines. XML to Data The XML (EXtensible Markup Language) to Data transformation contains some important cases. The most notable one is XML to HTML (HyperText Markup Language), as an HTML document ''is not'' an XML document. SGML origins The earliest transformation languages predate the advent of XML as an SGML profile, and thus accept input in arbitrary SGML rather than specifically XML. These include the SGML-to-SGML link process definition (LPD) format defined as part of the SGML standard itself; in SGML (but not XML), the LPD f ...

HaXml
HaXml is a collection of utilities for parsing, filtering, transforming, and generating Extensible Markup Language (XML) documents using the programming language Haskell. Overview HaXml utilities include: * XML parser * XML validator * a separate error-correcting parser for HTML * pretty-printers for XML and HTML * stream parser for XML events * translator from DTD to Haskell * translator from XML Schema definitions to Haskell data types HaXml provides a combinator library with a set of higher-order functions which process the XML documents after they are represented using the native Haskell data types. The basic data type is Content which represents the document subset of XML. HaXml allows converting XML to Haskell data and vice versa, and XML to XML (by transforming or filtering). The common use of the HaXml's parser includes defining the method of traversing the XML data and it has the CFilter type (''content filter''), where type CFilter = Content -> ontent/code>. It m ...
