DeWitt and Michael Stonebraker] On January 8, a Database Column reader asked for our views on new distributed database research efforts, and we'll begin here with our views on MapReduce. This is a good time to discuss it, since the recent trade press has been filled with news of the revolution of so-called "cloud computing." This paradigm entails harnessing large numbers of (low-end) processors working in parallel to solve a computing problem. In effect, this suggests constructing a data center by lining up a large number of "jelly beans" rather than utilizing a much smaller number of high-end servers. For example, IBM and Google have announced plans to make a 1,000 processor cluster available to a few select universities to teach students how to program such clusters using a software tool called MapReduce [1].

  • A Survey on Preparing Data Sets for Data Mining Analysis Using Horizontal Aggregations in SQL Prashant B
    Volume 7, Issue 5, May 2017 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com A Survey on Preparing Data Sets for Data Mining Analysis using Horizontal Aggregations in SQL Prashant B. Rajole Department of Computer Engineering, MCOERC, Nasik, Maharashtra, India DOI: 10.23956/ijarcsse/V7I4/0199 Abstract— Data mining is the field which has effectiveness in real world scenarios. Data sets are prepared from accepted transactional databases for the purpose of data mining. A vast amount of time is needed for creating the dataset for the data mining analysis because data mining developers required to write multifaceted SQL queries and many tables are to be coupled to get the aggregated result. Here, we recommended simple, however powerful, techniques to generate SQL code to formulate aggregated columns in a very horizontal tabular page layout, getting a few numbers as opposed to one variety per short period. This new functions class is named horizontal aggregations. Data sets are build using horizontal aggregations with a horizontal de-normalized layout (e.g., observation- variable, point dimension, instance-feature) which is the standard layout required by most data mining algorithms. Building user-defined new aggregate function that aggregate numeric expressions and transpose results to produce a data set with a horizontal layout is focused in this paper. Horizontal aggregations represent an ex-tended form of traditional SQL aggregations in which it returns a set of values in a horizontal layout. It is a new class of aggregations that have similar behavior to SQL standard aggregations which produces tables with a horizontal layout.

  • Aggregate Calculations Alculations and Subqueries
    33 Aggregate Calculations and Subqueries Chapter Overview So far we have examined all the basic ways to query information from a single table, but there are many more powerful query tools in SQL. In this chapter we will examine two more. One uses aggregate functions to assemble rows of data into totals, counts, and other calculations. The other sets a query inside a query. This is called a subquery, and it provides tremendous extensions to the power of SQL. Chapter Objectives In this chapter, we will: ❍ Learn what aggregate functions are ❍ Write SQL queries to summarize data into aggregate calculations ❍ Learn what a subquery is and where it can be used in SQL ❍ Learn how to use subqueries in the WHERE clause ❍ Use the ANY and ALL keywords with subqueries Aggregate Functions We have already seen how to create calculated columns in a query. Aggregates are also calcula- tions, but in a very different way. A calculated column calculates based on the values of a single 49 50 Chapter Three—Aggregate Calculations and Subqueries row at a time. An aggregate calculation summarizes values from entire groups of rows. The word aggregate is one we don’t often use in everyday speech, but it simply means a summary calcula- tion, such as a total or average. The standard aggregate functions are: Standard Aggregate Functions Sum To calculate totals Avg To calculate averages Count To count the number of records Min To report the minimum value Max To report the maximum value Some database systems add other aggregates. For instance, Access adds standard deviation, variance, first, and last.
