Trifacta
Trifacta is a privately owned software company headquartered in San Francisco with offices in Bangalore, Boston, Berlin and London. The company was founded in October 2012 and primarily develops data wrangling software for data exploration and self-service data preparation on cloud and on-premises data platforms. Its platform, also named Trifacta, is "designed for analysts to explore, transform, and enrich raw data into clean and structured formats." Trifacta utilizes techniques in machine learning, data visualization, human-computer interaction, and parallel processing so non-technical users can work with large datasets. History The company was developed from a joint research project with Ph.D. and UC Berkeley Professor Joe Hellerstein, Ph.D. and University of Washington and former Stanford professor Jeffrey Heer, and Stanford Ph.D. Sean Kandel. The company created a software application that combines visual interaction with intelligent inference for the process of data tran ...

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, Inc. is an American computer software company based in Irvine, California, with offices worldwide. The company's products are used for data science and analytics. 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 2006, the software product Alteryx was released, which was a unified spatial and non-spatial data environm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. It is closely aligned with the ETL process. Backg ... [...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 be readily and accurately 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 wil ...

Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
