As a result, many basic questions concerning DBMS prioritization remain open.;This thesis studies the implementation of prioritization in DBMS (commonly in commercial applications) with high- and low-priority users. The goal is to provide high-priority users with performance isolation, whereby high-...
Advantage 1: Fault isolation A previously successful test case fails when mNew is added to what has been tested so far The fault must lie in mNew or the interface(s) between mNew and the rest of the product 优点2:存根不会被浪费掉 每个存根都在适当的步骤中扩展为相应的完整制品 Advantage ...
DAIS: A real-time data attack isolation system for commercial database applications DAIS is a COTS-DBMS-specific implementation of a general isolation algorithm that was developed previously (P. Liu et al., 2000). The design of the ... L Peng - Computer Security Applications Conference 被引量...
In many database systems, including IBM DB2 and Microsoft SQL Server, the ‘ARIES’ (Algorithms for Recovery and Isolation Exploiting Semantics) system is used to provide such durability. ARIES uses ‘write-ahead’ logging to record each change to an object in the database before the change is...
Out-of-order execution in SPARC64 V contributes to high performance. SPARC64 V implements a large branch history buffer to predict its instruction path. The history buffer is large enough to sustain a good prediction rate for large-scale programs such as DBMS and to support the advanced ...
Vulnerability Discussion: An isolation boundary provides access control and protects the integrity of the hardware, software, and firmware that perform security functions. Security functions are the hardware, software, and/or firmware of the information system responsible for enforcing the system ...
Ecosystem incompatibility: The proprietary data formats employed by CC DBs create isolation, impeding interoperability with external data consumers. These factors collectively contribute to the limited industrial uptake of CC, despite its theoretical advantages. Our prior research introduced Thespis [12], a...
COVID-19 has led to an increase in mental health problems such as mental illness, depression, and suicide due to the social isolation and the social disconnection of vulnerable individuals. This study developed a healthcare analysis technology to assess individual mental and physical health conditions...
2)一致性(Consistency):数据库要一直处于一致的状态,事务的运行不会改变数据库原本的一致性约束。3)独立性(Isolation):指并发的事务之间不会相互影响,一个事务要访问的数据正在被另一个事务修改,那么在另一个事务提交之前,看到的数据是未改变的。4)持久
Unlike modern approaches, our solution does not depend on intermediate proxy that we believe a single point of breakdown and a blockage limiting accessibility as well as scalability of representative cloud database services. Secure DBaaS put together existing cryptographic methods, isolation and novel ...
