Mongo with Eclipse

This is a simple program


In Eclipse create following 3 classes n add relevant mongo libraray
(in eclipse)
     RC on project -> properties-> java build path -> libraries tab -> add external JARs....
  (in net beans also same)  
     RC on project -> properties->libraries tab -> add JARs/Folder ......
make sure u start mongo server b4 executing java program

NoSql

1)
Advance stuff can be taken from tutorial point
http://www.tutorialspoint.com/mongodb/
u can learn abt relationshiops (embedded docs and references)

(but it is using console )

2)
more details about mongo crud operations etc
http://docs.mongodb.org/manual/reference/method/db.collection.find/

foreing keys
using generated object ids (1:n)
{
   "name": "Tom Benzamin",
   age:23
   "dep_ids": ObjectId("543b968daac4771b60848b8a")
   
}
(m:n)

{
   "_id":ObjectId("52ffc33cd85242f436000001"),
   "contact": "987654321",
   "dob": "01-01-1991",
   "name": "Tom Benzamin",
   "address_ids": [
      ObjectId("52ffc4a5d85242602e000000"),
      ObjectId("52ffc4a5d85242602e000001")
   ]
}

or just use _id field to reference..
need to separately retrieve and display

3)
 Using mongoVUE
install mongoVUE
      1 start d server

• Extract MongoDB zip file and move its contents to a location of your choice (eg: c:\mongodb).
• install mongoVUE (next next etc)
• create folder called "data" parallel to bin folder inside mongodb folder
• mongod.exe --dbpath "C:\mondogb\data"  This will show waiting for connections message on the console output which indicates that the mongod.exe process is running successfully.

     2 start monogoVUE (graphical interface)

            create connection...   server:localhost port:27017  ..give any name

NoSql console

NOSQL
This is a very brief summary with links to refer further

1. http://www.youtube.com/watch?v=2ajlfURobd8

• A you tube video explaining how to use mongo db (which is using NoSql) for basic operations using console

1. first go inside bin n start server "mongod" in a command prompt
2. In another command prompt go inside bin, type mongo

                       (automatically connects to test db)

                       use db_mydb

                       //creating records and inserting to employee table

                        emp1=(name :"mal" )

                       db.employee.save(emp1);

                      //directly inserting

                      db.employee.insert((name : "Malsha"));

                         //view

                       db.employee.find();

                      //counting records

                      db.employee.count();

                         //updating

                       //adding new,deleting existing field of a record

                using $set n $unset

                      / /deleting

                       using remove
