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.

Alteryx
Alteryx is an American computer software company based in Irvine, California, with a development center in Broomfield, Colorado. The company's products are used for data science and analytics. The software is designed to make advanced analytics accessible to any data worker. History SRC LLC, the predecessor to Alteryx, was founded in 1997 by Dean Stoecker, Olivia Duane Adams and Ned Harding. SRC developed the first online data engine for delivering demographic-based mapping and reporting shortly after being founded. In 1998, SRC released Allocate, a data engine incorporating geographically organized U.S. Census data that allows users to manipulate, analyze and map data. Solocast was developed in 1998, which was software that allowed customers to do customer segmentation analysis. In 2000, SRC LLC entered into a contract with the U.S. Census Bureau that resulted in a modified version of its Allocate software being included on CD-ROMs of Census Data sold by the Bureau. In ...

Data Wrangling
Data wrangling, sometimes referred to as data munging, is the process of transforming and mapping data from one " raw" data form into another format with the intent of making it more appropriate and valuable for a variety of downstream purposes such as analytics. The goal of data wrangling is to assure quality and useful data. Data analysts typically spend the majority of their time in the process of data wrangling compared to the actual analysis of the data. The process of data wrangling may include further munging, data visualization, data aggregation, training a statistical model, as well as many other potential uses. Data wrangling typically follows a set of general steps which begin with extracting the data in a raw form from the data source, "munging" the raw data (e.g. sorting) or parsing the data into predefined data structures, and finally depositing the resulting content into a data sink for storage and future use. Background The "wrangler" non-technical term is of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Data Preparation
Data preparation is the act of manipulating (or pre-processing) raw data (which may come from disparate data sources) into a form that can readily and accurately be analysed, e.g. for business purposes. Data preparation is the first step in data analytics projects and can include many discrete tasks such as loading data or data ingestion, data fusion, data cleaning, data augmentation, and data delivery. The issues to be dealt with fall into two main categories: * systematic errors involving large numbers of data records, probably because they have come from different sources; * individual errors affecting small numbers of data records, probably due to errors in the original data entry. Data specification The first step is to set out a full and detailed specification of the format of each data field and what the entries mean. This should take careful account of: * most importantly, consultation with the users of the data * any available specification of the system which will use ...

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entities f ...
