摘要： Versioning and concurrency control architecture of data operations on data of a data source by multiple independent clients of a user. Data operation messages between the clients and the data source are intercepted and tracked for serialization control to a data view instance of the data source. The architecture can be located as an always-on centrally-located system (e.g., mid-tier), accommodate data operations that include create, read, update, delete, and query (CRUDQ) against data sources, and provides support for distributed transactions, locking, versioning, and reliable messaging, for example, for data sources that do not expose such capabilities. A hash is employed for version control and to control changes at the data source. The central system also provides logic for the individual CRUDQ operations, and granular error classification to enable retries whenever possible.

摘要： Aspects of the subject matter described herein relate database virtualization. In aspects, clusters of database servers may be located at various locations of the Internet. When a client seeks to access a logical database, the client may send a logical server and logical database name in a data structure. These names may be used to find a physical server(s) and database(s) that correspond to the logical database. Once the location is determined, a proxy component is used to intercept and/or forward communications between the client and the physical server(s) and database(s) corresponding to the logical database. Using this system, a client may access data from a logical database without knowing the physical address of the logical user database.
摘要翻译：本文描述的主题的方面涉及数据库虚拟化。在方面，数据库服务器的集群可以位于因特网的各个位置。当客户端寻求访问逻辑数据库时，客户端可以在数据结构中发送逻辑服务器和逻辑数据库名称。这些名称可用于查找与逻辑数据库对应的物理服务器和数据库。一旦确定了位置，代理组件被用于拦截和/或转发客户端与对应于逻辑数据库的物理服务器和数据库之间的通信。使用该系统，客户端可以在不知道逻辑用户数据库的物理地址的情况下从逻辑数据库访问数据。

摘要： An apparatus for suppressing power frequency common mode interference in a bioelectrical signal measuring system includes a driving circuit configured to amplify and change the phase of a common mode interference signal to produce a first driving signal, wherein the common mode interference signal is extracted from a plurality of first electrodes attached to a patient; phase compensating and processing circuitry electrically connected to the driving circuit for receiving the first driving signal, the phase compensating and processing circuitry configured to produce a second driving signal by phase-compensating the first driving signal based on a characteristic value of power frequency interference in a bioelectrical signal acquired through the plurality of first electrodes; and a switch to receive the first driving signal and the second driving signal, the switch configured to selectively switch between providing the first driving signal and providing the second driving signal to a second electrode attached to the patient.
