Getting Started with SQLiteby file systems – efficient data access amongst large sets of data, extremely granular security, highly standardized, cross‐ platform APIs, and structural independence. Databases support retrieving information Databases support security even down to individual fields in an extensible manner. Databases have highly standardized APIs for cross‐platform access. Lastly, applications that use databases are not dependent relational databases utilize the Structured Query Language (SQL) for data access and manipulation. SQL is highly standardized across databases. Although there are some differences, the significant aspects are0 码力 | 43 页 | 1.03 MB | 1 年前3
