NoSQL-PL2SQL-Simple version 0.23
================================
NoSQL::PL2SQL is an object oriented interface to access data:
## Instantiate a data definition (includes a data source)
my $datadef = new myDataDefinition ;
## provided the data definition includes "contactemail"
my $user = $datadef->contactemail('
[email protected]')->record ;
## prints something like "myDataDefinition=HASH(0x0000000)"
print $user ;
## prints the equivalent of "Jim Schueler"
print join ' ', @$user{ qw( firstname lastname ) } ;
## prints the equivalent of "TQISJIM"
print $user->{cpanid} ;
## modify and save the record
$user->{contactemail} = '
[email protected]' ;
$user->save ;
This example illustrates the simplicity of the API required to manage
data.
NoSQL::PL2SQL::Simple provides a shrinkwrapped version of NoSQL::PL2SQL.
There are only a few setup requirements:
1. Define a data source (DSN)
2. Create a data definition
The data source is an implementation of NoSQL::PL2SQL::DBI. The best
approach is to wrap the data source (dsn) in an abstract data source
subclass, which is described in the documentation.
The data definition is essentially a list of the object record
properties. The data definition only consists of properties that will
be queried. Essentially the same as an RDB table index.
NoSQL::PL2SQL::Simple requires a second DSN (RDB table) in addition to the
one used to store object data. However, both tables can be applied to
multiple data definition classes. With NoSQL::PL2SQL::Simple, It is
possible to build a fully normalized data set using only two tables.
