Q&A

4.  MongoDB is open source , document based
Database.
 Very popular now a days for its unique feature
 high performance, high availability, and easy
scalability.
 Documents (objects) map nicely to
programming language data types

5.  MongoDB is awesome Database.
 Every great software will be one or more Lag
 Password Complexity ( At least one capital
letter, one small letter, one letter and special
character )
 Every shift starts with resetting users
password, An UI needed to give a platform to
end-user to reset their password

6.  Web Interface is the easiest way to deploy
and reach all the end-user.
 Password can be reset for a user particular
server and particular Database.

7.  Python is a general-purpose interpreted,
interactive, object-oriented, and high-level
programming language.
 It has always been possible to use Python for
creating web sites but it was a rather tedious
task.Therefore, many frameworks and helper
tools have been created to faster and more
robust sites.

8.  Python Having Lot of core programming
Benefits, easier logic to implement and easier
to understand.
 Python used to connect with MongoDB using
PyMongo Driver.
 I needed a web based UI platform, python has
lot of Framework to use .

10.  PyMongo is a Python distribution containing
tools for working with MongoDB, and is the
recommended way to work with MongoDB
from Python.

11.  Bottle is a fast, simple and lightweightWSGI
micro web-framework for Python.
 It is distributed as a single file module and has
no dependencies other than the Python
Standard Library.

12.  Algorithm is simple
 Host the application in server and share the URL
 When user hit the url , it takes username from the
windows login(java script)
 Asks user to select the DB server.
 Lists the DB reside in that server.
 Asks for the New Password
 Checks the complexity meets requirement
 Resets the Password

try:
username = bottle.request.forms.get("username")
svrnames = bottle.request.forms.get("svrname")
db1 = str(bottle.request.forms.get("dbid"))

con =
pymongo.MongoClient("mongodb://username:password@h.o.s.t:port/dbname”)
answer =
con['admin'].system.users.find({"user":username,"db":db1}).count()
if answer == 1:
con[db1].add_user(username,pswd)
return bottle.template('changed',usr=username,svr=svrnames,dbs=db1)
else:
return
bottle.template('nochange',usr=username,dbs=db1,svr=svrnames)
con.close()

17.  I work as a DBA and resetting password all
the day is only not my job
 It will be usefull when you having quite big
users of Database, keep sending you ticket
for reset password
 Avoid lot of junk work and time
