Accessing database through expression language(EL)

[Rachit Kumar Saxena]

Hello all,just after studying the concept of expression language,from the marvellous book on the subject,HeadFirst Servlets and Jsp,I thought one thing,just as it was possible to access bean components,easily and displaying it(saving us from much coding in servlets and from the deprecated use of scriplets in our jsp page) on the screen,can we redirect that information to our database?If so how?Is this a good practise?Why?Why not?(in terms of space and time complexities).Is this a violation of MVC model and is it still prevalent?I will be highly obliged to hear your kind suggestions.
