Kexieen VISUELE DATABASE APPLICATIE LINUX AT THE OFFICE EEN VISUELE Kexi DATABASE APPLICATIE Kexi is gemaakt voor eindgebruikers die database applicaties willen bouwen, data willen invoeren en be- heren en query’s en rapporten maken. Met formulieren vereenvoudig je het gebruik van de uiteindelijke database applicaties. Matto Fransen Kexi is een visuele database applicatie en is oorspronke- lijk ontwikkeld als KOffice project. Het is bedacht als een Rapid Application Development tool voor databasesystemen die voldoende krachtig is. Door het gebruik van open standaarden en open source software is het voor iedereen bereik- baar en te gebruiken, op verschillen- de platformen en op verschillende type hardware. De ontwikkeling van Kexi begon reeds in 2005. In die tijd waren voor andere platformen wel visuele databases beschikbaar, zoals Microsoft Access, FileMaker, FoxPro, maar voor de open source bestu- ringssystemen bestond zoiets nog niet. Gebruikers van die systemen moesten kiezen uit een spreadsheet Screenshot 1: aanmaken tabel. of een gesofisticeerd databasesys- teem, zoals MySQL en ProgreSQL. zelfs op Microsoft Windows.

  • Best of a Decade on Opensource.Com 2010–2019
    Best of a decade on Opensource.com 2010–2019 In celebration of our 10-year anniversary Opensource.com/yearbook FROM THE EDITOR ............................. FROM THE EDITOR ............................. Dear reader, As we celebrate 10 years of publishing, our focus is on the people from all over the globe, in various roles, from diverse backgrounds, who have helped us explore the multitude of ways in which open source can improve our lives—from technology and programming to farming and design, and so much more. We are celebrating you because we’ve learned that growing this unique storytelling site demands that we do one thing better than all the rest: listen to and talk with our readers and writers. Over the years, we’ve gotten better at it. We regularly hold meetings where we review how articles performed with readers from the week before and discuss why we think that’s so. We brainstorm and pitch new and exciting article ideas to our writer community on a weekly basis. And we build and nurture close relationships with many writers who publish articles for us every month. As an editor, I never would have imagined my biggest responsibility would be community management and relationship building over copy editing and calendar planning. I’m so grateful for this because it’s made being a part of Opensource.com a deeply rewarding experience. In December, we closed out a decade of publishing by reaching a new, all-time record of over 2 million reads and over 1 million readers. For us, this validates and affirms the value we’ve learned to place on relationships with people in a world swirling with metrics and trends.
