DYNA16

The Dyalog Compiler analyses APL statements and prepares to execute them more efficiently than the traditional interpreter is able to, providing speed-ups of a factor of 2 or more on APL code operating on small arrays. Jay introduces the compiler and focuses on enhancements to it that are included in Dyalog version 15.0.

Data is everywhere and, while APL stands out for its ability to manipulate data, Dyalog raises it to a new level with its myriad of utilities, tools and techniques to read, write and manipulate data from a disparate set of sources. In this workshop we'll examine these tools and learn to read and write data from a variety of sources, including (but not limited to):

• Relational databases accessed using SQAPL
• Web techniques – XML, HTML, FTP, web scraping, JSON
• Different file formats – Text files, CSV files, Zip files, UTF-8 files
• Component files using DFS and native component file functions
• Third party formats – Microsoft Office, Google Docs
• Using Microsoft .NET Datasets from Dyalog APL
• vecdb – a new columnar database for "large data" analytics in Dyalog APL

Following on from Monday's presentations, this workshop examines the details of the new features. There will be time to ask questions and experiment with a pre-release of Dyalog version 15.0.

MiServer 3.0 can help you deliver your Dyalog application over the web. Whether as an interactive website or a web service, MiServer helps you combine the power of APL with the ubiquity of the web. In this workshop we will take a simple sample application and demonstrate building a website and a web service from the same core application business logic. Topics to be covered include:

• Building simple web pages, including a log-in dialog
• Interfacing to your application's business logic
• Exposing your application as a RESTful web service
