NAME DBIx::NoSQL - Experimental NoSQL-ish overlay for an SQL database VERSION version 0.0013 SYNOPSIS use DBIx::NoSQL; my $store = DBIx::NoSQL->new; $store->connect( 'store.sqlite' ); $store->set( 'Artist' => 'Smashing Pumpkins' => { name => 'Smashing Pumpkins', genre => 'rock', website => 'smashingpumpkins.com', } ); $store->set( 'Artist' => 'Tool' => { name => 'Tool', genre => 'rock', } ); $store->search( 'Artist' )->count; # 2 my $artist = $store->get( 'Artist' => 'Smashing Pumpkins' ); # Set up a (searchable) index on the name field $store->model( 'Artist' )->field( 'name' => ( index => 1 ) ); $store->model( 'Artist' )->reindex; for $artist ( $store->search( 'Artist' )->order_by( 'name DESC' )->all ) { ... } $store->model( 'Album' )->field( 'released' => ( index => 1, isa => 'DateTime' ) ); $store->set( 'Album' => 'Siamese Dream' => { artist => 'Smashing Pumpkins', released => DateTime->new( ... ), } ); my $album = $store->get( 'Album' => 'Siamese Dream' ); my $released = $album->{ released }; # The field is automatically inflated print $release->strftime( ... ); DESCRIPTION DBIx::NoSQL is a layer over DBI that presents a NoSQLish way to store and retrieve data. You do not need to prepare a schema beforehand to start putting data in! Currently, data setting/getting works by using JSON for serialization and SQLite as the database (though additional database support should not be difficult to implement) The API is fairly sane, though still an early "alpha." At the moment, a better name for this package might be "DBIx::NoSQLite" USAGE $store = DBIx::NoSQL->new Returns a new DBIx::NoSQL store $store->connect( $path ) Connect to (creating if necessary) the SQLite database located at $path $store->set( $model, $key, $value ) Set $key (a string) to $value (a HASH reference) in $model If $model has index, this command will also update the index entry corresponding to $key $value = $store->get( $model, $key ) Get $value matching $key in $model $value = $store->delete( $model, $key ) Delete the entry matching $key in $model If $model has index, this command will also delete the index entry corresponding to $key Search USAGE $search = $store->search( $model, [ $where ] ) $search = $store->search( 'Artist' => { name => { -like => 'Smashing%' } } ) Return a DBIx::NoSQL::Search object for $model, filtering on the optional $where An index is required for the filtering columns Refer to SQL::Abstract for the format of $where (actually uses DBIx::Class::SQLMaker under the hood) @all = $search->all Returns every result for $search in a list Returns an empty list if nothing is found $result = $search->next Returns the next item found for $search via "$search->cursor" Returns undef if nothing is left for $search $sth = $search->cursor->sth Returns the DBI sth (statement handle) for $search $search = $search->search( $where ) Further refine the search in the same way "$search->where( ... )" does $search = $search->where( $where ) $search = $search->where( { genre => 'rock' } ) Further refine $search with the given $where A new object is cloned from the original, which is left untouched An index is required for the filtering columns Refer to SQL::Abstract for the format of $where (actually uses DBIx::Class::SQLMaker under the hood) $search = $search->order_by( $order_by ) $search->order_by( 'name DESC' ) $search->order_by([ 'name DESC', 'age' ]) Return the results in the given order A new object is cloned from the original, which is left untouched An index is required for the ordering columns Refer to SQL::Abstract for the format of $order_by (actually uses DBIx::Class::SQLMaker under the hood) ...
