The document discusses why the author believes MongoDB is excellent. It provides examples of how MongoDB allows for easy setup with no language barriers, excellent geolocation support, lightning fast performance, and schema-less JSON data. The document includes sample PHP code demonstrating how to create a database and collection, insert data, and perform a geoNear query to find the nearest locations.

2. PERSPECTIVE

RECOGNITION
( starting with a mug and ending with a master )

9. CONFESSION #1

10. CONFESSION #1
I'M NO MASTER
( but I do know how to make the most of things )

11. CONFESSION #2

12. CONFESSION #2
IT'S REALLY EASY
( once you've got it all set up )

13. FOR
EXAMPLE

14. THERE IS NO SPOON !!!
( or need to leave your app )

15. NO LANGUAGE BARRIERS !!!
( all the logic is in one place )

16. Why
?
mongoDB

17. EXCELLENT GEOLOCATION SUPPORT
( have you ever heard of Foursquare ...? )

18. IT'S LIGHTENING FAST !!!
( some say 6,000 times faster in fact )

19. SCHEMA-LESS JSON DATA
( otherwise known as freedom )

20. REPLICA-SETS & SHARDING
( load-balancing and auto back-ups built-in from day one )

21. LAST
BUT NOT
LEAST

22. GRIDFS
( media storage and serving )

23. EXAMPLE PHP
CODE

24. CREATE DB + COLLECTION + INSERT DATA
// MongoDB PHP Class
$m = new Mongo();
// Select Database & Collection (Table)
$db = $m->freesquare;
$collectiom = $db->places;
// Add Document (Add a Record)
$obj = array(
"title" => "KL MongoDB User-Group",
"loc" => array(
"lng" => 101.67646,
"lat" => 3.127896
)
)
$results = $collection->insert($obj);

25. HAVING ADDED SEVERAL PLACES
// Assuming collection is defined
// We can now add the GeoSpatial Index
$collection->ensureIndex(array("loc"=>"2d");
// Defining my current location
$my_location = array(101.67646, 3.127896);
// Find Nearest Locations
$nearest_place = $collection->command(array(
"geoNear" => "loc",
"near" => $my_location,
"spherical" => true,
"num" => 1)
)
// Ready for AJAX listeners
echo json_encode($nearest_place);
