Feed: Liquid Web. Author: Sam Mcwright; Its 3 am on Sunday morning and your cell phone is ringing. It’s the CEO of your company. Quickly, you pinch yourself to see if you are dreaming. Nope, not a dream. You wipe the cold out of your eyes, clear your throat and reluctantly answer the call. The CEO is obviously shaken and by the sound of his tone, it appears something detrimental has occurred. He anxiously exclaims the business is losing money by the second. As your CEO continues speaking, you being the IT Manager, vaguely remember a meeting you had a ... Read More

Feed: Planet MySQL; Author: Mark Callaghan; I am wary of papers with performance results for too many products.Too many means including results from systems for which you lack expertise. Wary means I have less faith in the comparison even when the ideas in the paper are awesome. I have expertise in MySQL, MongoDB, RocksDB, WiredTiger and InnoDB but even for them I have made and acknowledged ridiculous mistakes.Database configuration is too hard. There are too many options, most of them aren't significant and the approach is bottom-up. I an expert on this -- in addition to years of tuning I ... Read More

Feed: SAS Blogs. Author: Joao Oliveira. Companies are increasingly recognising that getting value from the Internet of Things (IoT) requires analytics on the edge – specifically, artificial intelligence-powered analytics. It is, however, not as simple as that. Getting the most out of analytics on the edge requires the right  platform. Based on my experience with analytics, AI and/or decision models on the edge, I have outlined a number of important requirements for your platform below. Getting the most out of analytics on the edge requires the right  platform. Data management Delivering trustable decisions requires good data management. This includes accessing ... Read More

Artificial Intelligence – Cloud and Edge implementations takes an engineering-led approach for the deployment of AI to Edge devices within the framework of the cloud. We often use the word ‘engineering’ in casual conversation. However, in this context, we attach a specific meaning to Engineering. Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The American Engineers' Council for Professional Development defines engineering as: (specific emphasis of interest highlighted) The creative application of scientific principles to design or develop structures, ...

Feed: Featured Blog Posts - Data Science Central. Author: Russell W Anderson. Originally published here. “The first thing you need to do is get all the data in the same place”. We all remember the mantra that launched a thousand painful IT projects. The argument was that this would enable a “360-degree view of the customer” or “data-driven” decisions. After millions of dollars and multi-year implementations, many companies are hard-pressed to quantify the business benefits of these initiatives. The telling term here is these efforts were supposed to ‘enable’ analytics, rather than deliver value. The ‘data first’ enterprise is misguided ... Read More

Feed: SAS Blogs. Author: Alfred Mukudu. Innovation comes in all shapes and sizes. Business value, though, lies in translating ideas into production. We saw in our recent Innovation at Scale study that this translation, or "operationalizing analytics," remains one of the biggest challenges. I asked Shane, Principal Technical Architect, to share his views on the role of architects in guiding analytics-enabled innovation, the convenience of multisource tools and the importance of interoperability. The architect’s role in operationalizing analytics. To get us started, please tell us how you came to be a software architect. I've got quite a mixed bag of ... Read More

Feed: AWS Architecture Blog. IntroductionWhen an IT team first contemplates reducing on-premises hardware they manage to support their workloads they often feel a tension between wanting to use cloud-native services versus taking a lift-and-shift approach. Cloud native services based on serverless designs could reduce costs and enable a solution that is easier to operate, but appears to be disruptive to end user processes and tools. A lift-and-shift migration, though it can eliminate on-premises hardware and maintain existing workflows, doesn’t eliminate the need to manage a server infrastructure, does nothing to improve a team’s agility in releasing enhancements after migration to ...

Feed: SAS Blogs. Author: Paul Jones. "Moving to cloud" is top of agenda for a lot of the customers I meet. They see the potential for agility or cost reduction. Interestingly when I was speaking to the CTO of one our customers that was an earlier adopter of cloud, he didn’t see an overall cost reduction and didn’t mind. But they did experience increased agility in IT which directly lead to business improvements and an impact on the bottom line. Food for thought. One of the biggest costs of running an analytics system can be the storage or database cost, ... Read More

Feed: Planet PostgreSQL. PostgreSQL 12 introduces the generated columns, columns that are automatically computed depending on a generation expression. The usage of generated columns is quite simple and can be summarized as follows: the column must be annotated with the GENERATED ALWAYS AS (...) STORED instruction; the expression in parentheses must use only IMMUTABLE functions and cannot use subqueries. For more specific constraints, see the official documentation. Please note I’ve indicated the STORED clause because at the moment PostgreSQL supports only that kind of columns: a STORED generated column is saved on disk storage as a normal column would be, ...
