User Data Management with MongoDB
Download as PPTX, PDF3 likes8,259 views
This document discusses modeling and querying user data with MongoDB. It provides examples of modeling user account information, activities, check-ins, and clicks in different MongoDB collections. The document recommends mapping categories of user data to collections and extending the data model over time as new use cases emerge. It also demonstrates querying and aggregating the user data through examples like finding places near a location, filtering check-ins by time, and auditing a user's clicks.

User Data Management with MongoDB
- 1. Solutions Architect, MongoDB Heather Kirksey #MongoDB User Data Management with MongoDB
- 2. Agenda
- 3. Agenda • High Level Overview – MongoDB – User Data • Modeling & Querying User Data – Insurance Company User Data – User Check-Ins • Extending the Data Model for Future Use Cases – Tracking UserActivity – Social Media
- 4. MongoDB is a(n) ___________ database • Document • Open source • High performance • Horizontally scalable • Full featured
- 5. User Data • Account Information – Name, address, etc. – Account status – Notes • Activity Streams – Posts, tweets, likes, check-ins – Recording user actions • Social Networks – Friends, connections – Groups, tags
- 6. Data Modeling Exercise • Insurance Company Data • Account information – Name, address, etc – Account status – Notes
- 8. Data Modeling Example User Opened Date: 05/26/2013 Status: Successful Account Modified Date: 06/04/2013 Status: Added spouse User Call Log Date: 01/22/2014 Type: Complaint
- 9. Insurance Company Site User Opened Date: 05/26/2013 Status: Successful Account Modified Date: 06/04/2013 Status: Added spouse User Call Log Date: 01/22/2014 Type: Complaint 2 types of data 2 types of data
- 10. Rule of Thumb • Categories of data map well to MongoDB Collections Policies Activities
- 11. Policies policy = { name: “John Smith” employer: “10gen”, address: “555 Fictional Ave”, e-mail: “[email protected]”, spouse: “Yes” , dependents: “No”, dates: [ {start: 5/26/2013 10:12:00}, end: 5/26/2023 10:12:00}],
- 12. Activities activity = { user-id: “JohnSmith421” type: “account-opening” , status: “Success”, dates: 5/26/2013 10:12:00, related-doc: “/customer/JohnSmith421/open .pdf” } User Opened Account Date: 05/26/2013 Status: Success Account Modified Date: 06/04/2013 Action: Added Spouse User Call Log Date: 01/22/2014 Type: Complaint
- 13. User Check-Ins • Activity Streams – Posts, tweets, check-ins – Recording user actions
- 14. Places Q: Current location A: Places near location User Generated Content Places
- 15. Inserting a Place var p = { name: “MongoDB HQ”, address:“229 W 43rd St”, city: “NewYork”, zip: “10036”, tags: [“mongoDB”,“business”], latlong: [40.0, 72.0], tips: [{user:“John Smith”, time: “3/15/2013”,tip:“Make sure to stop by for office hours!”}]} > db.posts.save(p)
- 16. Updating Tips db.places.update({name: “MongoDB HQ”}, {$push :{tips: {user: “John”, time:3/10/2014, tip: “stop by for office hours on Wednesdays from 4-6”}}})
- 17. Querying Our Places • Creating Indexes • db.places.ensureIndex({tags:1}) • db.places.ensureIndex({name:1}) • db.places.ensureIndex({latlong:”2d”}) • Finding Places • db.places.find({latlong:{$near:[40,70]}}) • Regular Expressions • db.places.find({name: /^typeaheadstring/) • Using Tags • db.places.find({tags: “business”})
- 18. User Check Ins Record User Check-Ins Check-Ins Users Stats Users Stats
- 19. Users user1 = { name: “John Smith” e-mail: “[email protected]”, check-ins: [4b97e62bf1d8c7152c9ccb74, 5a20e62bf1d8c736ab] } checkins [] = ObjectId reference to Check-Ins Collection
- 20. Check-Ins user1 = { place: “MongoDB HQ”, ts: 9/20/2010 10:12:00, userId: <object id of user> } Every Check-In is Two Operations • Insert a Check-In Object (check-ins collection) • Update ($push) user object with check-in ID (users collection)
- 21. Simple Stats db.checkins.find({place: “MongoDB HQ”) db.checkins.find({place: “MongoDB HQ”}) .sort({ts:-1}).limit(10) db.checkins.find({place: “MongoDB HQ”, ts: {$gt: midnight}}).count()
- 22. Stats w/ MapReduce mapFunc = function() {emit(this.place, 1);} reduceFunc = function(key, values) {return Array.sum(values);} res = db.checkins.mapReduce(mapFunc,reduceFunc, {query: {timestamp: {$gt:nowminus3hrs}}}) res = [{_id:”MongoDB HQ”, value: 17}, … , …] …or try using the aggregation framework!
- 23. Adding More User Data User Opened Date: 05/26/2013 Status: Successful Account Modified Date: 06/04/2013 Status: Added spouse User Call Log Date: 01/22/2014 Type: Complaint
- 25. Each Click Creates a New Doc Policies Activities Clicks
- 26. Clicks click = { user: “JohnSmith”, ts: 9/20/2010 10:12:00, link: “http://some-link-here.com/wherever” } Now we can audit user activity... db.clicks.find({user:”JohnSmith”}).sort({ts:-1}) Show me all of John’s clicks sorted by timestamp.
- 27. Extending the Schema user1 = { name: “John Smith” e-mail: “[email protected]”, check-ins: [4b97e62bf1d8c7152c9ccb74, 5a20e62bf1d8c736ab] }
- 28. Extending the Schema user1 = { name: “John Smith” e-mail: “[email protected]”, check-ins: [4b97e62bf1d8c7152c9ccb74, 5a20e62bf1d 8c736ab] } friends: [7b47j62bk1d3c5621c1icv90, 1h11p62bf1d8 c716za]
- 29. Takeaways • User data fits well in MongoDB – Flexible data model – Stay agile; make changes – Many customers in production • Application patterns drive data design – Optimize data model for queries – Primary use cases drive design • Adding features is easy – Create new data structures – Extend existing
