Interface DataAccessObject

All Superinterfaces:: DAOView

public interface DataAccessObject
extends DAOView

Gere acessos a dados tabulares lidos de um data source.
Aborda-se a interacção com os dados a um nivel mais elevado permitindo assim ao utilizador concentrar-se na sua lógica de programação em vez de codificar o acesso aos dados.
Mantem associado a toda a informação um conjunto de flags que depois permitem a sincronização dos dados em memória com os do data source.
Nesta fase suporta os seguintes data sources:

Base de dados acedida por JDBC
Objectos serializados (apenas leitura)
XML com estrutura fixa (apenas leitura e apenas com tags já definidas)

Wish List

Suporte de rowid
Suporte de serial
Lock ao registo
Implementação sob a forma de bean
Funcionamento distribuido (com EJB)
Politica de lock/isolamento
Novas caracteristicas do JDBC 2.0 (bulk update, bulk insert, etc)
Implementação do interface RowSet (JDBC 2.0)
Escrita de XML
XML com formatos diferentes
Escrita de Objectos serializados
Dynaset totalmente configurável (apenas parte das colunas dinâmicas)
Exportações diversas
Definição a partir de definição de query
