An entity represents a grouping of attributes around a single, key, unifying information concept, for example, person, product, order or payment.
一个实体表示围绕一个单独的、关键的、统一的信息概念进行属性分组，例如人、产品、订单或支付。
The typical method is to look up the entity by its primary key, because that will guarantee a unique result.
典型的方法是根据实体的主关键字进行查询，因为这可以保证产生一个独一无二的结果。
An entity's primary key is the attribute or set of attributes that distinguish one instance of the entity from another.
实体的主键是使该实体的一个实例区别于其他实例的一个或一组属性。
However, in many cases, an entity of importance is a subset of a record, or spans several tables and requires data to be joined through a common key.
但是，在很多情况下，重要的实体是一个记录的一个子集，或者跨多个表，需要通过公共键链接数据。
Multiple attributes in the entity may be combined to form a composite primary key.
实体中的多个属性可以组合成一个复合的主键。
The private key remains under the protection of the entity to which it belongs.
私有密钥一直处于其所属实体的保护之下。
We also use a primary key class, constructed from the values comprising the EJB primary key, to make it easy to specify the primary key as a single entity.
我们还使用由组成ejb主键的值构建的主键类使得把主键指定为一个单独的实体很容易。
Thus, if one encrypts a message using the public key of an entity, then it is guaranteed that only the entity can decrypt the message.
这样，如果使用实体的公钥加密消息，那么可以保证只有该实体能够解密此消息。
The private key is only known (or should only be known) to the entity that owns the key pair.
私钥（或应该）只有拥有密钥对的实体知道。
Your entity class must have matching fields on the class or it can embed the key as an embeddable key
您的实体类必须在类上具有匹配字段，或者它可以作为可嵌入键嵌入该键
In this test, we created a single entity named OgisCustomer, which has four member attributes including the primary key (SRCSEQ).
在该测试中，我们创建了一个名为ogiscustomer的实体，它有包括主键(SRCSEQ)在内的4个成员属性。
RDA's content assist key (ctrl+space) displays the defined words when you select an entity or attribute name Figure 4 shows.
当选择一个实体或属性的名称时，RDA的内容辅助键（ctrl+space）会显示已定义的词，如图4 所示。
On the primary key Tasks page, select deptno as the primary key for the Department entity.
在主要关键字Tasks页面中，选择deptno以作为Department实体的主要关键字。
If there is an existing collection of runners, the new runner instance key is added to it; otherwise, a new collection is created and the runner's key (the id property on the entity) is added to it.
如果有一个现成的runners的collection，则新的runner实例键将添加到它；否则，将创建一个新的collection，且这个runner的键(实体上的id属性)将添加到它。
To find an individual entity by its key, you simply invoke the get method, which takes a class type and the key.
为根据键找到个别实体，您仅需调用get方法，该方法接受一个类类型和键。
The key to the dependency-injection approach is that you query data by injecting the Class of the entity that the DAO will be querying, along with defining the generic type.
依赖项注入方式的关键是，在查询数据时，要注入DAO将查询的实体的Class并定义泛型类型。
For example, if account Numbers are assigned across all types of accounts, account type may need to be used along with account Number to form the primary key of the accounts entity.
例如，如果所有类型的账户都被指定一个AccountNumber，那么可能需要使用AccountType和AccountNumber一起作为Accounts实体的主键。
The relationship is represented by a new CMP entity bean called Attendee, having two fields (three if we count the primary key field).
用名为attendee的新CMP实体bean表示关系，该bean有两个字段(如果加上主键字段则有三个)。
Each record saved in the datastore, also called an entity, requires a primary key.
保存在数据存储中的每一条记录，即实体，都需要有一个主键。
Digital certificates address this problem by certifying that a public key belongs to a named entity.
通过认证一个公钥属于一个命名的实体，数字证书解决了这个问题。
When an SSL-protected page is requested, the browser identifies the server as a trusted entity and initiates a handshake to pass encryption key information back and forth.
当请求一个SSL 保护的页面时，浏览器认为服务器是一个可信任的实体，并且启用一个连接来回传递加密的信息。
An immediate question that comes to mind is how to be assured that the public key being used is indeed bound to a legitimate entity and not to someone else.
这时会在脑海中立即出现一个问题，即怎样确保正在使用的公钥的确被绑定到合法实体上而没有绑定到其它实体上。
That is, if concurrent transactions update an entity bean with same primary key, updates could get lost.
如果并发事务用同样的主键更新实体bean 时，更新资料将会丢失。
In the real world, the certificates are typically themselves signed by some trusted authority such as VeriSign or an internal entity so you know that the public key is legitimate.
在现实世界中，证书通常由一些受信任的机构(如versign)或者某个内部实体进行签名，这样您便可以知道公钥是合法的。
The entity bean is a very simple example, named Person, which has attributes firstName and lastName, and a key field named id.
实体bean是一个很简易的实例，名为Person，具有firstName和lastName属性以及一个主字段，名为id。
"True" indicates that the public key corresponding to the private key used for signing does belong to the entity that claims to have signed the docs.
true “表明，用于签名的私钥所对应的公钥的确属于那个宣称对该文档进行了签名的实体。”
