Feed: AWS Big Data Blog. Have you ever been faced with many different data sources in different formats that need to be analyzed together to drive value and insights?  You need to be able to query, analyze, process, and visualize all your data as one canonical dataset, regardless of the data source or original format.In this post, I walk through using AWS Glue to create a query optimized, canonical dataset on Amazon S3 from three different datasets and formats. Then, I use Amazon Athena and Amazon QuickSight to query against that data quickly and easily. AWS Glue overview AWS Glue ... Read More

Feed: SAS Blogs. Author: Stephen Foerster. The Cloud Analytic Server (CAS for short) is SAS’ latest high-performance, scalable, in-memory analytic data server.  In this post, I’d like to discuss the CAS physical data model, i.e.what features CAS offers for data storage, and how to use them to maximize performance in CAS (and consequently SAS Visual Analytics 8.1 too). So, specifically let’s answer the question: What CAS physical table storage features can we use to get better performance in CAS and SAS Visual Analytics/CAS? CAS Physical Table Storage Features The following data storage features affect how CAS tables are physically structured: ... Read More

Feed: Planet PostgreSQL. Char() Char() Char(1) Char(1) If used as a boolean flag, use the boolean type instead Varchar2() Varchar() Timestamp Timestamptz In general, we recommend storing timestamps as time stamp with time zone (timestamptz), which is equivalent to Oracle’s timestamp with local time zone. This stores all values in UTC, even if the server or db client are in different timezones which avoids a lot of problems. But, some app code might have to be changed to timezone aware types – if significant, use the “timestamp” without timezone to minimize migration changes. Date Timestamptz PostgreSQL “Date” type stores the ... Read More

Feed: AWS Big Data Blog. Deriving insights from large datasets is central to nearly every industry, and life sciences is no exception. To combat the rising cost of bringing drugs to market, pharmaceutical companies are looking for ways to optimize their drug development processes. They are turning to big data analytics to better quantify the effect that their drug compounds have on different populations and to look for new clinical indications for existing drugs.A real world evidence (RWE) platform is loosely defined as an integrated set of services and products that life sciences companies use to securely acquire, store, and ...

You cannot imagine how much I hated mathematics back in my school days. Especially geometry and all the Sin, Cos and Radians stuff. Now I’m older, (and eventually) smarter and want to thank my teachers for not giving up! For ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Gregory Thompson. Let’s start with the bottom line - there is no excuse for virtually any company today, regardless of size or manpower (and within reason), not to be making data analyics a part of their normal business routines. Traditional objections such as cost, resources and expertise no longer cut the mustard.  As many observers have noted, a company’s internally generated data is a key asset that needs to be leveraged in the same way as any other corporate asset if the business is to survive and thrive in today’s increasingly ...
