正しい言い方

避ける言い方

• 数据库 loosely to refer to any collection of data files or spreadsheets — 数据库 specifically refers to a structured, software-managed system for storing, querying, and managing data; for unstructured data collections use 数据集 (dataset) or 数据仓库 (data warehouse) as appropriate; calling a folder of spreadsheets a 数据库 is technically inaccurate
