和長輩們聊天總是很有趣的。即使那是一句老生常談，從長輩提攜的口吻中說出，依然受用。
6/26 的謝師宴，和賴暎杰老師坐在一起，我是這麼問的：「研究遇到瓶頸時，是怎麼面對的。」
「每天都多學會一件事，就不用擔心。」

Data::Model
Data::Model is a new ORM created by yappo, Its usage style is similar to DataMapper and Jifty::DBI.
Different from most famous equivalent, Data::Model handles multi-database. In order to do that, every model was appointed its database and table name in addition to its schema specification.
Let's see a simple example:
This is a simplest model in Data::Model, Only two DDL in it.
The first,
The second, pass the table name and schema to
Wait... Because Data::Model is too young to do auto_migration, we simply write
Though Data::Model is too young to have some important feature such as validator and hook, even has no ability to handle relation between two table. The prototype is really exciting.

Let's see a simple example:
This is a simplest model in Data::Model, Only two DDL in it.
The first,
base_driver( $driver ) specify which database the model would connect to. $driver is a Data::Model::Driver::DBI object. Write those diffusion code in every model is really not perlish, so we extract all possible drivers to MyApp::DB::driver().The second, pass the table name and schema to
install_model(), this step is the same as above two ORM system. and then, all thing done. By the way, columns() is the best syntax sugar provided by Data::Model::Schema.Wait... Because Data::Model is too young to do auto_migration, we simply write
MyApp::DB::make_schema() to do that. Finally, we could do simple CRUD in our application. as below.Though Data::Model is too young to have some important feature such as validator and hook, even has no ability to handle relation between two table. The prototype is really exciting.
