For a long time, since a large number of (or even almost all) Java applications rely on databases, it has been a hot topic for programmers to use the Java language to access databases efficiently, reliably, and concisely. The newly released Java SE 6 is also upgraded in this regard, providing programmers with many useful new features. Specifically, Java SE 6 has an embedded 100% database system written in Java. In addition, Java 6 began to support a series of new features and attributes of JDBC

I. Overview of DB-API Python supports a number of different databases. Because different seller servers result in different network protocols for database communication. In earlier versions of Python, each database had its own Python module, all of which worked in different ways and provided different functions. This method is not easy to write code that can run on multiple database server types, so the DB-

During the process of generating SQLite database files on the SD card in Android today, we found that A. DB-Journal file with the same name as the database file with a size of 0 is generated. I do not understand the purpose of this file, so Google's SQLite official documentation found that the file is used as follows: This file is a temporary log file of SQLite. It is mainly used for the SQLite transaction rollback mechanism and is generated at the be
