For application developers and enterprises looking for an end-to-end solution that combines the long-term, deep analytics capability of the data warehouse or Hadoop with the operational and in-memory analytics power of VoltDB, the Export delivers the operational capabilities of VoltDB (ingest, interactions, transaction, real-time analytics) while enabling data to be moved out of VoltDB once the data has been processed and is no longer of immediate value. Export pushes data at high speed to a historical system that can provide deep historical analytics (including reporting, complex analysis, large storage capacities). Figure 1: VoltDB enables developers to take advantage of the cyclical nature of the import-export data cycle. For example, inflows of data can be filtered and acted upon based on rules loaded into VoltDB. Based on this filtered and processed export stream, updated rules are generated in Hadoop and frequently reloaded into VoltDB. VoltDB Export enables data to arrive in your analytic store sooner, and allows deep analytics to be leveraged with radically lower latency. © VoltDB, Inc. 209 Burlington Road, Suite 203, Bedford, MA 01730 voltdb.com Follow VoltDB.

  • Product 360: Retail and Consumer Industries
    PRODUCT 360: RETAIL AND CONSUMER INDUSTRIES MARKLOGIC WHITE PAPER • NOVEMBER 2015 PRODUCT INFORMATION IS COMPLEX A major challenge for Retail and Consumer companies today is product proliferation and product complexity. An electronics retailer for example may have over 70,000 products in its catalog, while it is not uncommon for an industrial distributor to have over a million products and represent over 1,000 suppliers. Products HD typically have short shelf lives. In electronics for example it’s not uncommon for a new model to be released every year. And, a “Product” is not just a physical SKU (stock keeping unit) but a complex combination of structured HD and unstructured data that helps consumers search for, evaluate, compare, and choose their desired purchase. Product information includes a variety of data elements Product information includes a wide variety of data elements which are generated and stored in multiple locations, for example: WHY IS “PRODUCT 360” • Product descriptive information (e.g. size, color, IMPORTANT? material, nutritional information, usage, and other Creating, maintaining, and managing a 360 degree view elements that define it) of products is at the core of competitive differentiation • Digital images and videos – and in fact even survival – for retail and consumer • Customer ratings and reviews companies. • Dynamic pricing and promotions • Availability in-stock Key benefits of a Product 360 include: • Consumer loyalty information (who’s most likely to buy it) REVENUE GROWTH • Related products and accessories Today just 3% of on-line e-commerce transactions actually result in a sale. E-Commerce is the fastest These data elements often sit in different databases and growing channel for retailers, and sales via e-commerce legacy systems, making accessing them a challenge.

A database is a collection of information or data which are organized in such a way that it can be easily accessed, managed and retrieved. Database is abbreviated ad DB. Different definitions of database. “a usually large collection of data organized especially for rapid search and retrieval (as by a computer) an online database” (merriam-webster) “a comprehensive collection of related data organized for convenient access, generally in a computer.” (dictionary) A database is an organized collection of data. (Wikipedia) What is data? It is used as both singular and plural form. It can be a quantity, symbol or character on which operations are performed. Data is information which are converted into digital form. Growth of Database Database was evolved in 1960's started with the hierarchical database. Relational database was invented by EF Codd in 1970s while object oriented database was invented in 1980s. In 1990s object oriented database rose with the growth of object oriented programming languages. Nowadays, databases with SQL and NoSQL are popular. Elements of Database Database elements are fields, rows, columns, tables. All these are building blocks of database.

  • HTAP WP.Indd
    Hybrid Transaction and Analytical Processing with NuoDB Whitepaper Core Tech Technical Whitepaper Hybrid Transaction and Analytical Processing with NuoDB Abstract NuoDB is a distributed SQL database management system that provides a simpler, more cost effective, and ultimately higher-scale approach to hybrid transaction and analytical processing (HTAP). In this paper, we explain the architectural basis for this assertion, and describe an HTAP example to illustrate these unique characteristics. What Is HTAP And Why Is It Important? The combination of simultaneous transactional workloads (“operational”) and analytics workloads (business intelligence, Big Data etc.) is a concept that is “ gaining traction among database vendors and industry analysts. Gartner will Data-driven businesses be publishing research on the topic in the next 12 months under the “HTAP” often need real-time moniker, HTAP meaning Hybrid Transaction/Analytical Processing. discovery and analysis HTAP is about spotting trends and being aware of leading indicators in order of transactional data to take immediate action. For example, an online retailer uses HTAP to find to make meaningful out what products are currently trending as best sellers in the last hour. changes immediately. He sees snow shovels are selling well and reacts by putting a snow shovel ” promotion on the home page to leverage the trend. Much of Big Data analytics has focused on information discovery, i.e., essentially using Hadoop for batch-oriented storing and querying of large amounts of data sometimes referred to as “data lakes.” However, data-driven businesses often need real-time discovery and analysis of transactional data to make meaningful changes immediately. Real-time discovery and analysis requires repeatable analytics on very recent data.

  • A New HOAP? Hybrid Operational- Analytic Processing and the Future
    451 RESEARCH REPRINT REPORT REPRINT A new HOAP? Hybrid operational- analytic processing and the future of the database market MATT ASLETT, JAMES CURTIS 04 DEC 2017 Data from 451 Research’s Total Data Market Monitor indicates that databases designed to support a combination of operational and analytical processing workloads will quickly become mainstream, at least for new application projects. THIS REPORT, LICENSED TO MEMSQL, DEVELOPED AND AS PROVIDED BY 451 RESEARCH, LLC, WAS PUBLISHED AS PART OF OUR SYNDICATED MARKET INSIGHT SUBSCRIPTION SERVICE. IT SHALL BE OWNED IN ITS ENTIRETY BY 451 RESEARCH, LLC. THIS REPORT IS SOLELY INTENDED FOR USE BY THE RECIPIENT AND MAY NOT BE REPRODUCED OR RE-POSTED, IN WHOLE OR IN PART, BY THE RE- CIPIENT WITHOUT EXPRESS PERMISSION FROM 451 RESEARCH. ©2017 451 Research, LLC | WWW.451RESEARCH.COM 451 RESEARCH REPRINT 451 Research has previously identified the emergence of a new breed of database providers with products that are positioned for a combination of operational and analytical workloads, as well as the systems of intelligence workloads that they are used for. Data from 451 Research’s Total Data Market Monitor suggests that these databases that are designed to support hybrid operational and analytic processing (HOAP) will quickly become mainstream in the coming years – at least for new application projects. THE 451 TAKE The blending of operational and analytical systems continues to add value for many organizations. And while hybrid systems may not be an ideal fit for every firm, there are many reasons they do make sense. Beyond the reduction in maintaining a separate transactional and analytical system, hybrid databases enable organizations to carry out analytics on incoming operational data, taking advantage of the ‘transaction window,’ which, if done right, could be incredibly lucrative.
