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

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:
