Arquivo Discussoes de Programacao e Tecnologia Bom dia alguem teria tabelas pronta para servir de exemplo para mim de pedido itensdepedido e produto pq estou tendo dificuldade em fazer mapeamento em um sistema q estou desenvolvendo, preciso que seja com o hibernate se tiver o Bean para inserir atualizar e editar tmb seria util só pra servir como exemplo para mim ou algum site que tenha o exemplo.
grato
Mais alguma coisa ?
rsrs só isso
As tabelas pode ser assim:
CLIENTE: Cod_Cliente, Nome,Endereço
PEDIDO: Num_Pedido,Prazo_Entrega Cod_Cliente, Cod_Vendedor,Data
ITEMPEDIDO: Num_Pedido,Cod_Produto,Quantidade
PRODUTO: Cód_Produto,Descrição,Unidade,ValUnidade.
VENDEDOR: Cod_Vendedor,Nome, Comissão,Salario

VENDEDOR: Cod_Vendedor,Nome, Comissão,Salario
Mais alguma coissa? O.o
O ideal é que vc tenha suas idéias, poste suas dificuldades aqui para que possamos te ajudar.
Se alguem sempre fizer para você, vc nunca irá aprender.
uahsduh não quer o db pronto de vez não?
mas avalie a sua necessidade, é fundindo seus neurônios que irá chegar a algo concreto…
Só não se esqueça de estudar um pouco de Diagram de entidade e relacionamento :shock:
ta me dando esse erro violento aki...
