无需为默认语言环境创建目录树或消息数据库；用于该语言环境的字符串已经被嵌入到代码中。
You don't need to create a directory tree or message database for the default locale; the strings for that locale are already embedded in the code.
存储库是文件存储和管理的中心位置（有时又被称为树）。
The repository is a central location where files are stored and managed (sometimes referred to as a tree).
“纯”意味着以标注上类型的树的形式存储和处理XML文档，这与商业关系数据库中以前的任何技术都不同。
"Pure" means that XML documents are stored and processed as type-annotated trees, unlike any previous technology in commercial relational databases.
ICMRME知识库表示为节点树，每个节点包含统计学知识和规则，用来帮助系统对文本进行分类。
An ICM RME KB is represented as a tree of nodes, with each node containing statistical knowledge or rules that assist the system in classifying text.
简单的非递归过程表达式并不能访问所有的元素，尽管许多库都包含有帮助功能，可以用于遍历树。
No simple non-recursive procedural expression accesses all elements, although many libraries include helper functions for walking the tree.
最常见的内存中数据库索引策略是T -树。
The most common in-memory database index strategy is called T-tree.
这些物种的信息是通过像国际植物园保护联盟植物收索和英国注册树这些数据库认证的。
The species were identified through databases such as the BGCI's PlantSearch and the UK Tree Register.
在本例中，当用户点击其中一个节点时，树将请求存储库加载条目，存储库将请求资源。
When a user clicks on one of the nodes in the example, the tree will ask the store to load the item and the store will request the resource.
为了简化，这个插件会刷新父节点来显示新添加的文档。最终，文件会添加到库中并显示在树中。
For simplicity, the plug-in refreshes the parent to show the newly added document, and in the end, the file is added to the library and shows up in the tree.
在快照模型中，整个存储库的每个修订(带优化以减少树的大小)的全部文件都被存储。
In the snapshot model, complete files are stored for the entire repository for each revision (with optimizations to reduce the size of the tree).
该层将一段源id映射到物理数据库，对于同一个物理地址的表，通过建立树来处理。
A forwarding layer maps ranges of source IDs to physical databases, and replication is handled by building a tree of such tables under the same forwarding address.
在分层存储库中(例如ldap)，基本项映射到目录信息树中标识DIT中子树顶部的一个项。
In a hierarchical repository, like LDAP, a base entry is mapped to an entry in the directory information tree that identifies the top of a subtree in the DIT.
