connect语句将一个数据库连接与一个用户名相关联。
The connect statement associates a database connection with a user name.
报表不是凭空而来的；它们需要某个数据源以向用户显示数据。
Reports don't appear from nowhere; they need a source of data to present to the user.
通过TP，用户可以手动地定义每个数据分区，包括将被包括到那个分区的值的范围。
With TP, the user can manually define each data partition, including the range of values to include in that data partition.
这个数据区域执行良好，大多数JCS用户将它指定为最先使用的默认缓存区域。
This data region performs well, and most JCS users designate it as the default cache region to use first.
这个数据可以来自用户也可以来自数据库。
用户如何查询可用实例的列表，如果它们是这个数据的不同实例(对每一个用户来说)。
How the user can query the list of available instances if they are separate instances of this data (for each user).
可以考虑使用一个数据库或者前端，以允许用户更新白名单和黑名单。
Consider using a database or a front end to allow users to update the whitelists and blacklists.
此外，每一个数据库拥有自己的目录表和用户表。
In addition, each database has its own catalog tables and user tables.
这些服务定义并使用数据操作层元数据，例如各个数据库位置、模式、规则、连接、用户ID和密码等等。
They define and use the data manipulation layer metadata, such as various database locations, schemas, rules, connections, user IDs and passwords, and so on.
每个数据地图保存单个表单实例的用户输入。
Each data map maintains the user input of a single form instance.
使用目录存储用户和组信息的优点是，可以将多个数据库集中于单个位置，以便降低用户和组的管理复杂性。
Using a directory to store user and group information has the advantage of centralizing databases in a single location for reducing user and group management complexity.
同时还假设已经下载了一个用户名和密码的清单到这个数据库中，并且当用户每次试图登陆到这个应用软件时，这个应用软件都会对它进行验证。
Also assume that a list of user names and passwords are preloaded into the database, and that the application verifies against this data every time a user attempts to log in to the application.
下一步是创建一个数据库来存储用户信息。
The next step is to create a database for storing user information.
这个数据库中有200个用户，但是在正式的测试中，仅仅选择了20个用户来运行相关场景。
There were 200 users in the database, but only 20 users were selected to run scenarios in the formal test.
本例中的模式是当第一个事务读取某个数据行时，它将加上时间戳和用户标识，这类似于悲观会话锁定的处理方式（稍后讨论）。
The pattern in this case is that when the first transaction reads a row it will "stamp" it with the identity of the user, similarly to how pessimistic session locking is handled (covered next).
IDS是一种强大的关系数据库服务器，它提供了许多特性，可以帮助每个数据库用户(从应用程序用户到管理员)完成复杂的活动。
IDS is a versatile relational database server that is powered with a wealth of features. It helps every database user, from an application user to an administrator, with complex activities.
注意，这里跳过访问JDBC驱动程序的配置步骤，因为我们假设每个数据库用户已经具备了这些配置。
Note that the step to configure access to JDBC drivers was skipped, since it is assumed that each database user already has these available.
每个用户连接分配一个数据库代理。
例如，用户可以从一个数据集提供的客户列表中选择一个客户。
For example, a user may select a customer from a list of customers provided by a data set.
用户与分区数据库的交互是通过一个数据库分区，即用于那个用户的协调分区创建的。
User interaction with a partitioned database occurs through one database partition, known as the coordinator partition for that user.
每个数据点增加1,000个用户，这里的CPU百分比是一小时的稳定状态下的平均值。
The CPU percent showed the average of the one-hour steady state of each 1,000-user increment.
基本上只要用户需要输入数据，就需要对这个数据进行验证。
Basically, in any scenario where a user must enter data, that data must be validated.
另外，当指定XML数据类型时，会向数据库用户公开这个数据模型。
Furthermore, this data model is exposed to database users when XML data type is specified.
类似地，每个数据库用户也都被赋予一个安全标签，这个标签将决定他/她可以访问哪些贴了标签的数据行或列。
Similarly, each database user is assigned a security label that determines which labeled data rows or columns he or she can access.
注意在同一下允许多个标签，会导致每用户操作出现多个数据库事务。
Note that multiple tags are allowed under the same, resulting in multiple database transactions per user action.
为了避免为每个数据源一一执行用户认证，可以利用单点登录。
To avoid having to authenticate the user for each data source, single sign-on techniques can be leveraged.
例如，接收某个数据对象的用户可能认为其不是包装数据对象，并尝试直接访问数据。
For example, a user receiving a DataObject may think that it is not a wrapper DataObject and try to access the data attributes directly.
DDL同样也包含了我们的两个数据库用户使用的grant语句。
The DDL also contains the GRANT statements for our two database users.
将这个数据库与您先前创建的用户数据库连接起来(图12)。
Link that database to the user database that you created earlier (Figure 12).
将这个数据库与您先前创建的用户数据库连接起来(图12)。
Link that database to the user database that you created earlier (Figure 12).
