- 2. Codelab
- 3. Who are we ? Who are we ?
- 4. Data and storage ● Most apps need storage ● Apps store data ● There is two types of data ○ Structured data ○ Unstructured data
- 5. What do we look for in a database ? Right structure to match our data Performance and Scale Features that help developers
- 6. Relational Relational designed for one thing, used for everything
- 7. Relational ● Query on any field ● In-place updates ● Two-dimensional storage ● Each field contains a single value ● Very structured schema (table) ● Normalization, process requires many tables, joins, indexes and poor data locality Oracle, MSSQL, MySQL, PostgreSQL, DB2 Primary key
- 8. Apps and Data today Modern apps use unstructured data Data growing in size and complexity Agile development Scalability and distribution
- 9. NoSQL Large volumes of rapidly changing structured, semi-structured, and unstructured data Object-oriented programming Geographically distributed scale-out architecture (We call this Horizontal scaling)
- 10. NoSQL Database Types Document databases MongoDB Graph stores Neo4J Key-value stores Redis Wide-column stores Cassandra and HBase
- 11. NoSQL or RDBMS for my-app ? You know the answer now….
- 12. MongoDB Finally we can talk about this “MongoDB” MongoDB is a NoSQL Document Database It’s free and open source
- 13. What the hell is a document A Document is not a word or a pdf document It’s a JSON Object JSON == JavaScript Object Notation
- 15. Scalability
- 16. Consistency
- 17. Developers super-powers with MongoDB
- 18. Let’s Play Let’s play some MongoDB now To your keyboards !
- 19. Import data set mongoimport --db codelab --collection companies --drop --file ~/Desktop/companies.json
- 23. find db.getCollection("restaurants").find({$or: [ {"cuisine":"Italian"}, {"address.zipcode":"10075"} ] } )
- 28. update db.getCollection("restaurants").update({"name":"Juni"}, {$set :{"cuisine": "American (New)"}})
- 30. Aggregate db.getCollection("restaurants").aggregate( [ {$match:{"borough":"Queens", "cuisine":"Brazilian"} }, {$group:{"_id":"$address.zipcode", "count":{$sum :1}} ] )
