6. What does MongoDB Looks like?

8. How does a pair of SQL DBAs start supporting MongoDB?
We are not experts

9. What is MongoDB?
MongoDB is an open source database that uses a document-oriented data model
Classified as a NoSQL database program, MongoDB uses JSON-like documents

11. JSON – JavaScript Object Notation
A human-readable, plain text format for expressing structured data with support in many programming languages

12. MongoDB stores data records as BSON documents.
BSON is a binary representation of JSON documents, it contains more data types than JSON.

17. Why use MongoDB? You must store unstructured data
You have a very high write load (without transactions)
You need to handle more reads & writes than a single server can handle
You need a solution that can easily scale-out(sharding)
You work with tables with very inconsistent schemas
You need high availability solution built-in (ReplicaSets)
You need high performance (most of the data is stored in ram)
You need built in geospatial functions

18. Why you wouldn’t want to use MongoDB?
No support for transactions
Limited support for joins
No support for triggers
Document size limit (16 mb)
Your data is relational
You don’t want duplicate data.

19. Use Cases for MongoDB

20. Is MongoDB going to replace SQL Server?NO
Know your data
Know your application

21. Supporting 2 different databases is hard enough right?

The core components in the MongoDB package are: mongod, the core database process; mongos  (mongo sharding service) the controller and query router for sharded clusters; and mongo the interactive MongoDB Shell.
mongod is the primary process for the MongoDB system. It handles data requests, manages data access, and performs background management operations.
mongo is an interactive JavaScript shell interface to MongoDB, which provides a powerful interface for systems administrators as well as a way for developers to test queries and operations directly with the database. mongo also provides a fully functional JavaScript environment for use with a MongoDB. This document addresses the basic invocation of the mongo shell and an overview of its usage.
mongotop provides a method to track the amount of time a MongoDB instance spends reading and writing data. mongotop provides statistics on a per-collection level. By default, mongotop returns values every second.
The mongostat utility provides a quick overview of the status of a currently running mongod and mongos instance. mongostat is functionally similar to the UNIX/Linux file system utility vmstat, but provides data regarding mongod and mongos instances.
