1. GRAPH DATABASES WILL CHANGE YOUR FREAKIN’ LIFE ED FINKLER LEAD DEVELOPER & HEAD OF DEVELOPER CULTURE
2. WHAT IS?
3. I’VE GOT A DOPE VISUALIZATION FOR YOU DOGG This Effin Guy HEY I JUST DOWNLOADED D3.JS
4. NO. INCORRECT.
5. GRAPH THEORY AND MATH AND STUFF
6. I WAS TOLD THERE WOULD BE NO MATH
7. IT’S ABOUT DATA
8. MANY DATA Visualiza!on by Kim Albrecht

9. BUT IGNORE THAT
10. ZOOOOOO000M IN
11. HOW DO WE REPRESENT A THING OR AN ENTITY OR WHATEVER YOU WANT TO CALL IT
12. RELATIONAL DATABASES USE A LEDGER-STYLE STRUCTURE
13. USUALLY A THING IS ONE ROW IN A TABLE
14. YOU USE CONSTRAINTS TO REPRESENT RELATIONSHIPS BETWEEN THINGS
15. THE TABLE STRUCTURE IS GREAT FOR CONSTRAINING INPUT AND LOCKING THINGS DOWN
16. CAN GET COMPLEX AND RIGID WHEN REPRESENTING RELATIONSHIPS
17. LET’S TALK ABOUT [NEO4J] GRAPHS
18. GRAPHS ARE MUCH SIMPLER
19. THINGS ARE NODES OR VERTICES
20. NODES HAVE PROPERTIES { KEYS: “VALUES” }
21. NODES HAVE LABELS TO TELL YOU WHAT TYPE OF THING IT IS
22. n:Person id: 1234 first_name: “Ed” last_name: “Finkler”
23. NODES ARE CONNECTED BY RELATIONSHIPS OR EDGES
24. RELATIONSHIPS HAVE A TYPE AND A DIRECTION AND CAN HAVE PROPERTIES
25. n:Person id: 4321 first_name: “Griffin” last_name: “Finkler” n:Person id: 1234 first_name: “Ed” last_name: “Finkler” r:CHILD_OF created: 2002
26. DOTS AND LINES ALL THE WAY DOWN
27. IT’S SIMPLER
28. IT’S MORE POWERFUL
29. WHEN THE MEANING IS IN THE RELATIONSHIPS
30. SOMETIMES DIRECT RELATIONSHIPS BUT THAT’S NOT HARD TO DO WITH RELATIONAL DBS PERSON A PERSON B
31. SOMETIMES INDIRECT RELATIONSHIPS THIS IS HARDER TO DO TRAVERSE WITH RELATIONAL DATABASES ACTOR A ACTOR B MOVIE A DIRECTOR A MOVIE B ACTOR C
32. SCALING UP INDIRECT RELATIONSHIPS
33. ANSWERING QUESTIONS YOU DIDN’T EXPECT
34. YOU WANT TO KNOW HOW MANY PEOPLE WHO BOUGHT A TOASTER IN KANSAS AND HAVE A CRIMINAL RECORD USED YESTERDAY’S COUPON? NO. GET THE HELL OUT. This Effin Guy ASKING YOUR BACKEND DEV IF YOU CAN GET SOME NEW DATA OUT OF THE DB
35. WITH A GRAPH, YOU COULD ANSWER THAT QUESTION. IF YOU HAVE ALL THAT DATA IN THERE, AND THERE ARE PATHS BETWEEN THEM.
36. YOU CAN ADD MORE RELATIONSHIPS AS NEEDED AND STILL BE PERFORMANT
37. EGOTISTICAL LIVE CODING TIME
38. I’M PROBABLY GONNA FUNK THIS UP
39. CMD+TAB, SON
40. THANK GOD THAT’S OVER
41. GRAPHS AREN’T MAGIC
42. GRAPHS DON’T SOLVE ALL YOUR PROBLEMS
43. IF YOU’RE ASKING QUESTIONS ABOUT THE RELATIONSHIPS, THEY ARE REALLY NICE AND REALLY POWERFUL AND SOMETIMES SEEM LIKE WITCHCRAFT
44. ESPECIALLY IF YOU HAVE MANY DATAS
