Simple Bus transfer algorithm: Three tables (most simplistic, do not consider fuzzy query, one-way street and other things):1, the Site table Stop (stop_id,stop_name)2, route table line (line_id,line_name)3, Route site table (point line Relational table) Linestops (line_id, stop_id, seq) the SEQ here refers to the order of a site in a line. Now analyze the algorithm:1, Direct LineFirst of all, according to two site names to obtain the respective IDs o
