Data Shown in a List Made Easy For Apps-Powerful Geography Searches

  These recent videos show how easy it is to incorporate 'location aware' searches on data shown in a list into your mobile and desktop web application development efforts using Alpha's upcoming product There are many use cases. For example a mobile application for sales people would show all customers that are within (say) 1, 10 and 15 miles of the sales person’s current location.

UX Component: List Control - Geography Searches

If the List control is based on a SQL database that supports the Geography data type (SQL Server, MySQL, Oracle, DB2 all do), then you can perform 'geography' searches on the data in the List. For example, you can find all records that are within (say) 10 miles of your current location. The 'current location' can be automatically supplied by the device. Alternatively, you might want to know which records are within a specified radius of a certain point (that you can specify by latitude/longitude value), or by address. In addition, when the results of the search are displayed in the List you might want to group the data in 'logical' groups. For example, the first group might be 'Records within 1 mile of your current location', the next group might be 'Records between 1 and 5 miles from your current location' and so on. In this video we show how this is easily done.  

UX Component: List Control - Geography Searches for Mobile App Development

Searching data to show records that are near the current location of a mobile device is an extremely common need in mobile applications and mobile app development situations. For example, the well know iOS application, Yelp, shows all restaurants that are near you or Flixster shows you all the movie houses that are within 1, 5, 10, 15 miles of where you are. In this video we build on the example show in the previous video and we show how a simple mobile application can be built that does a 'geography' search on data in a List control. Powerful but easy and quick to do.
