What is MongoDB

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

What MongoDB Lag with

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

…MongoDB Lag

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.

How I over come with PYTHON

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.

…Pyton

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 .

PyMongo

…PyMongo

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

About Bottle framework

Bottle is a fast, simple and lightweight WSGI micro web-framework for Python.

It is distributed as a single file module and has no dependencies other than the Python Standard Library.

Code and Algorithm

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

bottle.run(reloader=True,debug=True,host=“127.0.0.1",port=8080)

Where it is useful

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
