Basic requirement for accessing eresources
A digital environment is necessary for
accessioning and disseminated eresources. Retrieval Software is
produced locally and most of the
information is obtained by remote
accesses. The three major components
are for accessioning e- resources.

are following:JSTOR
Blackwell Publishers
Springer Verlag & Kluwer
American Chemical society etc.
E-Zine

is that a database allows storing data
and getting it or modifying. There
are to type of databases –
 Analytical Databases
 Operational Databases
Analytical Databases
Analytical Databases are primarily
static, read only databases , which
store archived, historical data used
for analysis. Web pages are
generated dynamically search
parameters.
Operational Databases
Operational databases allow to
modify that data. These types of
databases are usually used to track
real-time information.
