为此，需要维护一个日志；批量装载和导入程序常常将日志写入一个文件，但是在数据库中需要使用一个表。
For this, you need to keep a log; bulk load and import programs often log to a file, but inside the database you need to use a table.
不过处理程序也很容易写入数据库(XML：SAX：DBI)。
But the handler could just as easily write to a database (XML: : SAX: : DBI).
如果不保存它(如将它写入一个真正的文件，或者使用shelve模块或数据库)，则程序结束时，它将消失。
It will be gone when the program finishes if you do not take steps to save it (such as writing it to a real file, or using the shelve module or a database).
另一种管理数据库中写入争用的方法是为一些或所有应用程序数据评估使用NoSQL数据存储的可能性。
Another approach to managing write contention in the database is to evaluate the possibility of using NoSQL data stores for some or all of your application data.
在此模式中，一个应用程序将数据写入数据库，另一个应用程序从该数据库中读取数据。
In this case, one application writes data to a database, while the other applications read from the database.
如上所述，将应用程序数据保存在中央数据库中可以确保在集群环境中写入和一致地读取数据。
As mentioned above, keeping the application data in a central database ensures consistent server write and consistent read data in the cluster environment.
在您尝试伸缩应用程序时，常遇见的问题是数据库中的写入争用。
A common problem as you try to scale applications is write contention in the database.
这种数据写入和读取之间的延迟是由于执行读取的应用程序不知道执行写入的应用程序何时将数据写入数据库所造成的。
This lag between writing and reading of the data is due to the fact that the reading application isn't aware of when the data is written by the writing application.
这个JAR实用程序含有一个执行基于JPA 1.0的数据库交互的类，该数据库将用户从浏览器输入的数据写入数据库表。
This utility JAR contains a class that performs JPA 1.0 based interactions with a database that writes the data entered in a browser by the user to a database table.
使用相同的结果解析器方法，可以指示一个XQuery 1.0程序将输出写入一个XML数据库。
With the same results resolver approach, you can direct an XQuery 1.0 program to write output to an XML database.
EcoSpace能包含将对象写入DB 2数据库的“持久性处理程序”。
The EcoSpace can contain 'persistence handlers' that can write the objects away to a DB2 database.
例如，如果想让应用程序使用sqlite数据库，则需要将数据库文件的路径写入位于sqlobject. sqlite包的sqlite连接构建器中。
For instance, if you want your application to use a sqlite database, you need to pass the path to the database file into the sqlite connection builder located in the sqlobject.sqlite package.
针对实际应用的问题，提出一种基于数据库的文件上传方法，该方法通过表单提交文件信息，服务器端程序从多域数据流析取文件内容并直接写入数据库。
By sending the file information through HTML form, the Action on the server side extract the file from multipart stream and store it into the database.
