MongoDB for the SQL Server
- 1. MongoDB for the SQL Server Pro
- 2. What is MongoDB? • Open source NoSQL database • Document-oriented • Stores JSON-like documents (dynamic schemas) • Includes a strong query language (javascript) • Powerful, flexible indexing (including geospatial) • Sharding and replication • Cross-Platform (many drivers )
- 3. QUICKSTART - SETUP MONGODB Demo
- 4. Get MongoDB and Driver(s) • Quick download, zero install • Also get your driver (C# for us)
- 10. COMPARING DOCUMENT DATABASES TO RDBMS SYSTEMS Understanding more..
- 11. So which type of NoSQL? CAP… Consistency Availability Partition Tolerance CP = noSQL/column Hadoop Big Table H-base MemCacheDB (graph)? CA = SQL/RDBMS SQL Sever / SQL Azure Oracle MySQL AP = noSQL/document or key/value MongoDB DynamoDB CouchDB Cassandra Voldemort
- 12. DB Features for MongoDB & SQL Server primary keys and indexes queries with models for sorting / limiting results a strong typing system aggregations like SUM(), COUNT(), etc… Large object support
- 13. DB Features unique to Document DBs Collections, not Tables Query language, not T-SQL Idrefs, not Joins No pre-defined Schema • Aggregation Framework • Grouping or MapReduce Aggregations • No multi-document transactions No Transactions No Full-text search
- 14. Use 10gen Quick Reference Cards
- 15. DB Features of note in MongoDB • BSON supports more complex types (date, geo-spatial, etc…) • Supports dynamic queries via proprietary query language – Uses “find()” which returns a [lazy] cursor – Multi-key indexes can be created • Scalability via Replication and Sharding
- 16. Why use MongoDB? • Document-like • Semi-structured • Few Joins • Geospatial Data Structure • Large or Huge • Distributed • Unpredictable Data Volume
- 17. MongoDB Scenarios Document Management systems E-commerce (catalog portion only) Archiving / event logging Real time analytics (based on logging) Gaming Geospatial Mobile
- 18. IMPORTING DATA TO MONGODB Demo
- 19. Adding Data • Data must be in JSON format - converter • “Insert” CREATES a collection if needed
- 22. USING VELOCITY FOR MODELING Demo
- 23. Modeling Use short names • each name is saved for each document • can save up to 30% storage Keep collections small • Can create non- default (narrower) key • Document size maximum is 4 MB Use GridFS for BLOBs
- 24. Comparing…
- 26. Using Find Find, Fields, Sort, Count, Skip, Limit, Visualize or Export
- 28. Queries
- 29. Queries 2 …
- 30. Queries 3…
- 31. What is Grouping? • Similar to T-SQL ‘Group By’ • Written in javascript
- 32. What about Joins? No traditional joins in MongoDB Can use Arrays Can use Embedded Documents Can use DBRef Can De- normalize schema
- 33. About the Aggregation Framework • New in MongoDB 2.2 • Layer on top to facilitate easier query-writing
- 34. Query Tuning • Use best indexes – Evaluate use of _id – Add columns to index (specificity) – Multiple columns, most specific first – Can use fully covered indexing (indexOnly:true) – Test to make sure indexes are being used • Qty scanned s/b same as QTY returned • Use .explain
- 35. Understanding Explain • Query execution detail plan • Review number of scanned objects
- 36. ADD INDEXES TO MONGODB Understanding more
- 37. Modifying Data Update • alone does a replace Update w/ $set • does an update Update w/ $inc • increments Upserts • must be enabled • then insert if new, update if existing Multiple field updates • occur by default
- 38. Using Update
- 40. What is GridFS? • Used to hold objects larger than 16 MB
- 41. CONNECTING TO MONGODB WITH C# Demo
