As an answer to the question I asked yesterday ( the “New Master Data” object, identical to the existing one: a separate object or another solution? ), Someone recommended that I index the attribute.
After a long search on Google about what an “index” is in SQLite / Core Data, I’m afraid that I’m no closer to knowing exactly what it is and how it speeds up attribute-based fetching. Keep in mind that I know nothing about SQLite / databases in general, except for the vague idea of reading, path, path, too much about Core Data over the past few months.
