Using JSFiddle, You will be doing a bit of research for a web company. They want to be able to quickly find what users of an app have visited a geographical location within a certain period of time. The App has the user information and periodically polls and stores the location of the user using the GPS function of the phone. The App collects and stores millions of pieces of information an hour - so search efficiency is extremely important. The company wants you to design a storage scheme for the data that will allow you to quickly and easily determine if a user has visited a specific store or location, how often, and for how long. You must determine how you will store and retrieve the data and what types of data structure and organizational scheme you will use for the data. You will write a one page paper covering the "plan" for the data storage and search techniques that you will use to ensure that you have incredibly fast retrieval of the information for the proposed application. Please save you paper in PDF format before you submit. (be sure to back up your plan with web links and resources - so you will want to do some research. Also you will have to develop an algorithm to effectively determine if someone has actually visited a location - so you will have to think about that too.

I’m the co-founder at Sonda Sports - company processing data in the area of sports performance tracking. In the course of the development of our product, we created a GPS data engine, which is one of the finest technological advances of its type. The engine is the IN-MEMORY DATABASE management system to capture and analyze data with domain-specific query language. Written in Java 8 (extensively using Lambda Expressions and Generics ­ for execution speed and code maintainability) In-­memory persistence ­ for maximum performance (w​ith automatic f​ailover​­, maintains and restores data in the event of power failure). While our tests on real data were being conducted, we became aware of the high level of our results, and we are all in agreement that there are neither such solutions in the products already existing anywhere else in the world, nor can such results be provided by any of those products. If you are looking for blazingly fast real-time GPS data querying engine, this technology may interest you.
