It does not imply abandoning the concept of models, views and controllers.web2py comes with a Database Abstraction Layer (DAL), an API that maps Python objects into database objects such as queries, tables, and records.The DAL dynamically generates the SQL in real time using the specified dialect for the database back end, so that you do not have to write SQL code or learn different SQL dialects (the term SQL is used generically), and the application will be portable among different types of databases.When the next http request arrives, web2py tries to recycle a connection from the pool and use that for the new transaction.If there are no available connections in the pool, a new connection is established. The pool grows up to the minimum between the value of then connection pooling is not used.Notice that by default web2py uses utf8 character encoding for databases.
