-The graph below is a visual representation of the tables in the database. Each table includes an "id" as primary key (PK) and one or more foreign keys (FK) which point to the "id" columnn of a different table. It is by foreign keys that the tables are chained together in many-to-one relationships. The entity boxes for the tables include the names and datatypes of the columns where "tinyint" and "smallint" are two types of integer, "varchar" is a limited length, while "text" is an unlimited length text type.
+The graph below is a visual representation of the tables in the database. Each table includes an "id" as primary key (PK) and one or more foreign keys (FK) which point to the "id" columnn of a different table. It is by foreign keys that the tables are chained together in many-to-one relationships. The entity boxes for the tables include the names and datatypes of the columns where "tinyint" and "smallint" are two types of integer, "varchar" is a limited length, while "text" is an unlimited length text type. The three colours indicate the three different sources from which the tables are created. Tables in shaded blue are created from the same source as the core "text" table, i.e. the _Digest_ text as presented in Amanuensis, but they were separated to structure the information.
