PHP+MySQL Introduction Course. 24-28 September

When building complex web applications, HTML soon shows its limitations, and it becomes necesary to use a server-side programming language in order to create dynamic pages, database queries, etc. PHP is the most popular web programming language, which, together with a MySQL database, allows us to build powerful online applications. The SIE is organizing an introductory course on building web pages with PHP and MySQL, from September 24 to 28. In this course we will learn how to create simple dynamic web pages and how to interact with a MySQL database; some HTML, CSS and internet knowledge is required. The number of participants is limited to 10-12; if you are interested, just reply to the post in the SIE's Forum: http://venus/SIE/forum/viewtopic.php?p=415#415.

Web Collaboration and Content Management Systems

Web collaboration tools are applications used to plan and organize working groups. They usually contain calendar events, address books, time sheets, task managers, etc. shared by the group members. Among the many options available, here at the IAC we have selected and installed egroupware. Content Management Systems (CMS) are used to build general-purpose websites. Here at the IAC we use both Website Baker, a simple but complete CMS with which we build and develop conference and workshop web pages, and Joomla, a powerful, features-loaded CMS for more complex sites such as the Helas IT platform and Consolider-Ingenio-GTC. For more details, please read our SIEpedia article.

Jump on the on-line education bandwagon with Moodle!

As you probably remember, last year the SIE installed Moodle (a very popular course management system that can help teachers to build quality on-line courses) in the IAC external server: A number of courses have already made use of the platform during the last year, and with the new academic year about to start it is now the time to remind you that creating a new account is as simple as getting in touch with us (). At the same time, perhaps you are not aware that there are hundreds of modules that can increase Moodle's functionality (, but if you would like to add any of these, please let us know as soon as possible, since we will not be able to install new modules once the classes begin.
