SQLite Index Visualization

The term "indexes" serves both as the third-person singular present tense of the verb "to index" and as a plural noun form of "index." In contrast, "indices" is the traditional plural form of "index," particularly prevalent in mathematical and scientific contexts. While "indexes" is commonly used in general English, "indices" is often preferred in technical fields to maintain linguistic precision. Employing "indices" in such contexts helps distinguish between the action of indexing and the plural form of index, thereby enhancing clarity.

Says who with what authority?

All major RDBMS use the term "indexes".

FWIW, both are fine (https://www.nasdaq.com/articles/indexes-or-indices-whats-the...), and SQLite and PostgreSQL documentation (as two popular examples) use "indexes".

It depends on your audience. If you're catering to academics, use "indices." If you're catering to the general person, "indices" comes off as pompous.

Try pluralizing "time series". You won't get far.

So what I've seen in Finland is people using "time series" for the plural and "time serie" for the singular.

Nope. Academics prefer “indexes” when discussing databases.

I wonder if one could make a grammar-argument that it's like "Attorneys General." :p
