Persistence
The following mechanisms were recommended for Zamco
Application architecture for persistence
• The architecture uses JPA Entities to persist the data into the
relational database.
• JPA Entity provides composite view of relational tables to
easily manage the persistence and JPA query language
provides fast access to the table rows with optimized queries.
•
The
use
of
JPA
Entities
to
persist
the
data
increases
scalability across multiple nodes.
• JPA improves database
portability
because of database
independent JPA Query language.
Distribution
The following mechanisms were recommended for Zamco
Application architecture for distribution.
• The architecture uses remote stateless session beans for
accessing the business service from web tier. These
components act as the facade to the JPA Entity layer, which
are
designed
with
composite
model
to
support
container
managed relationship.
• This way we can distribute the business components by
deploying with multiple machines and they can be accessed
by the web tier components from remote. This will increase
the application's scalability as well.
