DBMS is an acronym for database management system and it can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Some examples of a database management system (DBMS) are RDBMS, Oracle, SQL server, PostgreSQL, dBASE, Clipper, MySQL, Microsoft Access, etc.
A DBMS commonly receives data update requests from application programs through the Open Database Connectivity ( ODBC ) driver in case of communication with other database management softwares.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.

Some of the ones towards the start may not be right but I gave it a go :)
def dx(fn, x, delta=0.001):
return (fn(x+delta) - fn(x))/delta
def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
for tries in xrange(maxtries):
err = fn(x) - value
if abs(err) < maxerr:
return x
slope = dx(fn, x)
x -= err/slope
raise ValueError('no solution found')
