Exploring Advanced SQL Techniques Using Analytic FunctionsZohar Elkayam
Session from ILOUG I presented in May, 2016
Even though DBAs and developers are writing SQL queries every day, it seems that advanced SQL techniques such as multi-dimension aggregation and analytic functions are still relatively remain unknown. In this session, we will explore some of the common real-world usages for analytic function, and understand how to take advantage of this great and useful tool. We will deep dive into ranking based on values and groups; understand aggregation of multiple dimensions without a group by; see how to do inter-row calculations, and much-much more…
Together we will see how we can unleash the power of analytics using Oracle 11g best practices and Oracle 12c new features.

Spring Day | Spring and Scala | Eberhard WolffJAX London
2011-10-31 | 09:45 AM - 10:30 AM
Spring is widely used in the Java world - but does it make any sense to combine it with Scala? This talk gives an answer and shows how and why Spring is useful in the Scala world. All areas of Spring such as Dependency Injection, Aspect-Oriented Programming and the Portable Service Abstraction as well as Spring MVC are covered.
"JavaScript in 2016" by Eduard Tomàs
Some years ago in a far far away company, Brendan Eich created JavaScript. A lot of things happened since then. Times changed, the web grown, the language itself was updated, and we as a developers need to adapt too. Last year the last standard of the language arose: ECMAScript 2015 is here, and has some new and interesting features. In this talk we will show the most relevant ones, and also we will introduce some interesting patterns that you can use in JavaScript: you'll learn how to master the language and made JavaScript your best ally to conquest the world!
OOW2016: Exploring Advanced SQL Techniques Using Analytic FunctionsZohar Elkayam

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”
