一次插入多行,每行有8000以上字符,SQLite使用事务速度 快于 access 一倍左右 SQLite查询速度极快,甚至快过SQL Server 2008 r2 10倍(因为MSSQL索引列不能超过900个字符,所以varchar(max)不能建索引) 单条数据插入速度比Access略慢,事务插入大量数据,在每行数据量不大时,远快于Access Access经常出现数据库坏的情况,...
SQLite supports many functions and has high performance, but it does not support stored procedures. SQL is made up of three parts: Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL). SQLite architecture is file-based. SQLite differs from other SQL...

Better Performance: The SQLite database allows for quick reading and writing operations. It's over 35% faster than the File system. Rather than reading and storing the entire file in memory, it only loads the data that is required.
Our data provider offers data fetching control (background, on-demand, pagination) and helps establish server-side data relationships. The refresh of specific records and selective column loading facilitate effective performance optimization. Microsoft technology support ...
A series of tests were run to measure the relative performance of SQLite 2.7.6, PostgreSQL 7.1.3, and MySQL 3.23.41. The following are general conclusions drawn from these experiments: SQLite 2.7.6 is significantly faster (sometimes as much as 10 or 20 times faster) than the default ...
