1. RavenDB
What is it?

3. Before we begin…
 Central Texas GiveCamp
 Developers
 Sponsors
 http://ctxgivecamp.org
 RavenDB Boot Camp
 September 5th-6th
 2-day hands-on workshop
 Headspring, Austin, TX
 http://headspring.com

4. Agenda
 NoSQL Crash Course
 Overview of RavenDB
 Development with RavenDB

5. Crash Course
NoSQuirreLs? But why?

6. History of the Datum
 We (the programmers) gave
birth to data
 We put it (the data) in memory
 We discovered a way to persist it
 So we put it in files
 And we had more problems to
solve…

7. From Data To Management
 Common problems
 Data retrieval
 Concurrent writes
 Optimize for space
 Data aggregation
 Lead to the introduction of
 RDBMS
 SQL

8. RDBMS + SQL
Strengths Limitations
 ACID  Scaling horizontally is hard
 Atomic
 Consistent  Scaling vertically is expensive
 Isolated  Object to relation mapping can
 Durable be difficult
 Relational
 Table / Row
 Rich query support
 Data Integrity
 Foreign Keys
 Enforced Schema

9. CAP Theorem

10. Polyglot Persistence
 Relational
 MS SQL Server
 MySQL
 Key-Value
 Redis
 Dynamo
 Column-Oriented
 BigTable
 Cassandra
 Document-Oriented
 MongoDB
 RavenDB

11. Key-Value
 Simplest of all data stores
 IDictionary<string, object>
 Key is a string
 Value is a blob
 Schema free
 Query by key
 Or key range sometimes
 Good candidate for
 User session storage
 Shopping carts

12. Document-Oriented
 Like a key-value store
 Document in known format
 JSON
 BSON
 XML
 Supports server side operations
 Good for
 Complex objects
 DDD Aggregates

13. Column-Oriented
 Not relational at all
 Schema free
 Concepts to understand
 Column families
 Row Keys
 Columns
 A Key Value Pair
 Good for
 Large amounts of sparse data

14. Is SQL Dead?
 Nope
 It’s still the strongest option for
 Reports
 Dynamic Aggregations
 Data integrity enforcement
 Remember
 NoSQL = Not Only SQL
 Or… NoSQuirreLs

15. RavenDB
The Very Brief Overview

16. What is it?
 It’s a document database
 Built on .NET for .NET
 JSON data storage
 Built on top of Lucene
 Open source
 Gets out of your way
 It just works
 Just code – studio not required

17. Features I Really Like
 Scalable via shards and/or replication
 Schema free
 Easy to learn and develop against
 Full power of Lucene
 Full-text search
 Faceted search
 Auto suggest
 More like this
 Multiple deployment options

18. Development
Oh yeah! It’s fun!

19. .NET Client API
 IDocumentStore
 Session factory
 Thread safe heavy weight object
 Thread safe
 Use single instance per application
 IDocumentSession
 Interacts with the database
 Not thread safe light weight object
 Implements Unit of Work pattern
 Use one per thread or web request

20. CRUD Operations
 Create
 IDocumentSession.Store(object)
 Retrieve
 IDocumentSession.Load<T>(string)
 Update
 Retrieve and modify
 Delete
 IDocumentSession.Delete(object)
 Don’t Forget
 IDocumentSession.SaveChanges()

21. Query Operations
 Rich LINQ support
 Basic Query
 IDocumentSession.Query<T>()
 Returns a IRavenQueryable<T>
 Implements IQueryable<T>
 Filtering
 Use a Where(…) clause
 Paging
 Use Skip(int) and Take(int)

22. Dynamic Indexes
 Automagically created on demand
 Raven learns about your application
 Dynamic indexes marked as temporary
 Removed if not used
 Promoted to permanent if used a lot

23. Static Indexes
 Do it your self
 It’s just a class
 That defines
 Implicit or explicit index name
 One or more map functions
 Optional reduce function
 Optional transform function
 May define many other options like
 Field options
 Storage
 Analysis

24. More to Learn
 Querying
 Using the query statistics
 Indexes
 More options
 Hierarchical indexes
 Polymorphic indexes
 Projections
 Document relationships
 Attachments
 Shards and Replication

25. Even More to Learn
 Advanced topics
 Transaction support
 Document metadata
 Spatial search
 Dynamic fields
 Database commands
 Server administration
 Deployment options
 Multi-tenancy
 Using bundles
