Microservice Project Construction II: database design

01, Basic personnel information and authority design

2, Course related database design

Database table information is :

Create database , The name is : course

One , Create sequence

create sequence base_case_questions_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_examination_site_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_multiple_choice_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_profession_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_rank_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_subject_year_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence base_thesis_title_seq increment by 1 minvalue 1 no maxvalue start with 1;
create sequence rel_examination_questions_seq increment by 1 minvalue 1 no maxvalue start with 1;
