- Transform conversion as a view, and when inserting into it, actually insert into 3 tables: conversion_table, conversion_method and conversion_param, so that method and parameter names are not repeated each time. - Similarly for helmert_tranformation, insert into helmert_transformation_tabl and coordinate_operation_method. This reduces the db size from 6 344 704 bytes to 5 853 184 bytes, without significant slowdown for queries.
