The data source view defines the capabilities of a data source control , and performs all the work necessary to retrieve data from the underlying data store and perform operations such as sorting , inserting , deleting , and updating 数据源视图定义数据源控件的功能，执行从基础数据存储区检索数据所必需的所有工作，并执行排序、插入、删除和更新等操作。
To set and restore the state of the database , some functions are needed , including insert , delete , update , refresh , etc . when going into particulars , sqlclient and olddb is included in the design of the frame 为了能够方便的设置以及恢复数据库的状态,需要提供一些基本的功能,包括插入、删除、修改、更新等等。在该面向数据库的单元测试框架具体实现方面,该框架针对sqlclient以及oledb两种数据接口。
Is that it uses a single map - wide lock , which must be held for the entirety of an insertion , removal , or retrieval operation , and sometimes even for the entirety of an iterator traversal . this prevents other threads from accessing the ）的可伸缩性的主要障碍是它使用了一个map范围（ map - wide ）的锁，为了保证插入、删除或者检索操作的完整性必须保持这样一个锁，而且有时候甚至还要为了保证迭代遍历操作的完整性保持这样一个锁。
As the scheme of information arrangement of corba is flat file style , which handles querying , deleting , and inserting information inefficiently compared to osi . a tree structure of managed objects arrangement like mib ( management information base ) has been used to provide efficient operation on managed objects . in addition , arrangement , definition , implementation and finding schemes for corba managed objects are also given by the tree structure 针对corba管理信息的组织采用类似于非结构化的文件方式，及其处理管理信息的查询、插入、删除等操作效率较低的缺陷，在corba管理中，提出采用类似于osi系统管理和snmp ( simplenetworkmanagementprotocol ，简单网络管理协议)管理的mib ( managementinformationbase ，管理信息库)树形组织与存储。
After locating the exact tandem repeats , we use them as seeds and expand them by wraparound dynamic aligning , and finally get all the valid approximate tandem repeats with insertion , deletion and dismatching . this is the algorithm for locating approximate tandem repeats . a software replocate is implemented , which can locate all the tandem repeats effectively in genome sequences 在此精确串联重复识别算法的基础上,把精确串联重复作为核,通过回绕动态规划比对将精确串联重复和它所在的序列片段进行比对,使精确串联重复序列扩展为具有插入、删除和错配结构的有效模糊串联重复。
