    Dana Singleterry, Oracle Corporation 
    In recent years, the world of application development has adopted new methodologies that aim to improve the quality and speed in which applications are being delivered. The introduction of innovative development approaches, such as test-driven development and agile development, gave rise to a set of new techniques and tools that enable those methodologies. Tools such as automatic-build utilities combined with continuous integration platforms, as well as enhanced collaborative tools such as wikis and code review utilities, aim to simplify the adoption of these new methodologies.

    Oracle Applications User Experience team members
    Ultan O'Broin and others write about their different experiences with Google Glass and how it is perceived internationally in the general public. "As a global Google Glass Explorer, I was drawn to the HuffPo's article about reactions to Google Glass in Spain. We have Explorers in Oracle, so I thought it would be interesting to hear from some about what reactions they’d encountered the around the world."

    Lucas Jellema, AMIS
    You should not judge a book by its cover. Doesn’t the same apply to computer applications? Well, apparently not. If the user interface is unappealing, unintuitive, and unproductive, the application stinks, no matter how good the machinery inside. This may not have been as true fifteen years ago as it is today; it is certainly rapidly becoming more of a reality every day.

    Carl Dudley, Tradba Ltd
    Joins are one of the most fundamental operations to be carried out on a relational database. ANSI defined the standard join syntax in SQL92 and Oracle now supports this syntax as well as its own non-standard syntax. Since the introduction of the ANSI syntax into the Oracle Database, there has been much debate as to which syntax to use. Oracle now recommends the adoption of the ANSI syntax, but the take-up appears to be patchy. This paper does not attempt to evaluate joins on a syntax basis but is designed to show some of the quirks and possibilities when processing joins.

    Letter from Editor
    By Karen Cannell, TH Technology
    As ODTUG opens a new chapter, commencing next quarter, our Journal will be entirely online and released in a distributed format. We will deliver one feature article and one or more of our regular columns right to odtug.com’s Tech Corner on a monthly basis. You will have the opportunity to give online feedback and comment on each article – and you know how we ODTUGgers like to exchange opinions!

    No worries, some things will stay the same—we will keep our same columns, so you can look forward to your favorites each quarter. We will also have greater opportunity and flexibility to bring you more varied content, to keep pace with the ever-growing family of Oracle development tools.

    Our aim is to bring delivery of the ODTUG Technical Journal in line with today’s social media options. These days our members are consuming more information online, and in shorter formats, such as blogs, podcasts, newsfeeds, and tweets, as opposed to formal whitepapers and other printed media. The times, they are a changin’, and ODTUG is keeping up. Join us!
