Scientific Data Mining in Astronomy
SCIENTIFIC DATA MINING IN ASTRONOMY Kirk D. Borne Department of Computational and Data Sciences, George Mason University, Fairfax, VA 22030, USA [email protected] Abstract We describe the application of data mining algorithms to research prob- lems in astronomy. We posit that data mining has always been fundamen- tal to astronomical research, since data mining is the basis of evidence- based discovery, including classification, clustering, and novelty discov- ery. These algorithms represent a major set of computational tools for discovery in large databases, which will be increasingly essential in the era of data-intensive astronomy. Historical examples of data mining in astronomy are reviewed, followed by a discussion of one of the largest data-producing projects anticipated for the coming decade: the Large Synoptic Survey Telescope (LSST). To facilitate data-driven discoveries in astronomy, we envision a new data-oriented research paradigm for astron- omy and astrophysics – astroinformatics. Astroinformatics is described as both a research approach and an educational imperative for modern data-intensive astronomy. An important application area for large time- domain sky surveys (such as LSST) is the rapid identification, charac- terization, and classification of real-time sky events (including moving objects, photometrically variable objects, and the appearance of tran- sients). We describe one possible implementation of a classification broker for such events, which incorporates several astroinformatics techniques: user annotation, semantic tagging, metadata markup, heterogeneous data integration, and distributed data mining. Examples of these types of collaborative classification and discovery approaches within other science disciplines are presented. arXiv:0911.0505v1 [astro-ph.IM] 3 Nov 2009 1 Introduction It has been said that astronomers have been doing data mining for centuries: “the data are mine, and you cannot have them!”. -
Data Quality Through Data Integration: How Integrating Your IDEA Data Will Help Improve Data Quality
center for the integration of IDEA Data Data Quality Through Data Integration: How Integrating Your IDEA Data Will Help Improve Data Quality July 2018 Authors: Sara Sinani & Fred Edora High-quality data is essential when looking at student-level data, including data specifically focused on students with disabilities. For state education agencies (SEAs), it is critical to have a solid foundation for how data is collected and stored to achieve high-quality data. The process of integrating the Individuals with Disabilities Education Act (IDEA) data into a statewide longitudinal data system (SLDS) or other general education data system not only provides SEAs with more complete data, but also helps SEAs improve accuracy of federal reporting, increase the quality of and access to data within and across data systems, and make better informed policy decisions related to students with disabilities. Through the data integration process, including mapping data elements, reviewing data governance processes, and documenting business rules, SEAs will have developed documented processes and policies that result in more integral data that can be used with more confidence. In this brief, the Center for the Integration of IDEA Data (CIID) provides scenarios based on the continuum of data integration by focusing on three specific scenarios along the integration continuum to illustrate how a robust integrated data system improves the quality of data. Scenario A: Siloed Data Systems Data systems where the data is housed in separate systems and State Education Agency databases are often referred to as “data silos.”1 These data silos are isolated from other data systems and databases. -

The majority of business processes in an organisation is nowadays already supported by some kind of implemented application, and the organisation must focus on making its operations more efficient. One of the ways of achieving this goal is the information exchange optimization across applications, assisted by the data integration from various applications; it is summarily known as Enterprise Application Integration (EAI). Without effective Enterprise Application Integration, a modern organisation cannot run its business processes to meet the ever increasing customer demands and have an up-to-date knowledge of its operations. Data integration is an important part of EAI. -
Declarative Access to Filesystem Data New Application Domains for XML Database Management Systems
Declarative Access to Filesystem Data New application domains for XML database management systems Alexander Holupirek Dissertation zur Erlangung des akademischen Grades Doktor der Naturwissenschaften (Dr. rer. nat.) Fachbereich Informatik und Informationswissenschaft Mathematisch-Naturwissenschaftliche Sektion Universität Konstanz Referenten: Prof. Dr. Marc H. Scholl Prof. Dr. Marcel Waldvogel Tag der mündlichen Prüfung: 17. Juli 2012 Abstract XML and state-of-the-art XML database management systems (XML-DBMSs) can play a leading role in far more application domains as it is currently the case. Even in their basic configuration, they entail all components necessary to act as central systems for complex search and retrieval tasks. They provide language-specific index- ing of full-text documents and can store structured, semi-structured and binary data. Besides, they offer a great variety of standardized languages (XQuery, XSLT, XQuery Full Text, etc.) to develop applications inside a pure XML technology stack. Benefits are obvious: Data, logic, and presentation tiers can operate on a single data model, and no conversions have to be applied when switching in between. This thesis deals with the design and development of XML/XQuery driven informa- tion architectures that process formerly heterogeneous data sources in a standardized and uniform manner. Filesystems and their vast amounts of different file types are a prime example for such a heterogeneous dataspace. A new XML dialect, the Filesystem Markup Language (FSML), is introduced to construct a database view of the filesystem and its contents. FSML provides a uniform view on the filesystem’s contents and allows developers to leverage the complete XML technology stack on filesystem data. -
Using the Qlik Data Integration Platform for Better Analytics
DATA SHEET DATA INTEGRATION Modern DataOps Using the Qlik Data Integration Platform for Better Analytics QLIK.COM INTRODUCTION Enabling DataOps for Analytics-Ready Data Qlik’s Data Integration Platform (formerly Attunity solutions) automates real-time data streaming, cataloging, and publishing, so you can quickly find and free analytics-ready data — and take action on it. In today’s hyper-competitive business climate, real-time insights are critical. Users need robust data integration and agile analytics solutions, to make decisions fast. Unlike traditional batch data movement and ETL scripting — which are slow, inflexible and labor intensive — Qlik’s data integration platform automates the creation of data streams from core transactional systems. It efficiently moves data to applications, warehouses, and lakes — on premise and in the cloud — and makes data immediately available via an Amazon-like catalog marketplace experience. With Qlik, users get the frictionless data agility they need to drive greater business value. Data consumers need better access to their data in real time. Many existing processess and technologies simply can’t keep up with this increasing demand, creating more complexity and tighter bottlenecks within IT. DataOps seeks to bring improvements to data integration. Borrowing methods from DevOps — which combines softward development (Dev) and IT operations (Ops) to improve the velocity, quality, predictability, and scale of software development and deployment — DataOps focuses on the practices and technologies for building and enhancing data pipelines to rapidly meet business analytics needs. Modern DataOps 2 Data Warehouse Automation Business needs are in a continual state of flux. Data sets are increasingly diverse. To meet the growing need for analytics-ready data delivery at the speed of now, Qlik’s Data Integration Platform automates the entire data warehouse lifecycle. -
