1 Universidade Federal de Mato Grosso Especialização em Banco de Dados SQL Multimedia and Application Packages — SQL/MM Still Image Fundamentos de Banco de Dados e Modelagem de Dados

2 Universidade Federal de Mato Grosso Especialização em Banco de Dados Introdução Padrão, baseado no SQL e em tipos estruturados definidos pelo usuário Dividido em partes independentes Definido pela ISO/IEC 13249-5:2003

3 Universidade Federal de Mato Grosso Especialização em Banco de Dados SQL Multimedia and Application Packages — SQL/MM Entre 91 e 92, um pequeno grupo de empresas operando pela IEEE definem SFQL Criticado por outras comunidades pelo 'sequestro' de palavras chaves. ex.: contains A organização dos padrões SQL nota conflitos nas extensões Tóquio 92, modelo objeto-relacional, bibliotecas de classe, métodos SQL/MM, mesma comissão ISO do SQL Padrão múltiplo, partes independentes, Framework
