we do not consider cryptographic methods of information protection, which, as applied to information systems, ensure security of data storage and transfer. The focus in this paper is on the models based on access control and information flow control ...
As the DBs need to work alongside information flow controlled programming languages and operating systems for tracking flows, there is a need to enforce the security policy not only on the DBMS but also on the application platform. Due to the underlying requirement of decentralization, it calls ...

ELECTROTEHNICS, ELECTRONICS, AUTOMATIC CONTROL, INFORMATICS VENDOR-INDEPENDENT DATABASE APPLICATIONS – AN ARCHITECTURAL APPROACH The ability to switch between different Database Management Systems (DBMS) is a requirement for many database applications in which effort was invested by many researchers. The...
Cooperative Adaptive Cruise Control (CACC) systems have the potential to increase roadway capacity and mitigate traffic congestion thanks to the short following distance enabled by inter vehicle communication. However, due to limitations in acceleration and deceleration capabilities of CACC systems, deactivat...
Upload the cloud credentials to the instance using dbms_cloud.create_credential procedure. Load tpcds data and tables in your instance. A dump of tpcds scale 1 is available in the OCI location, where you can copy data to your own bucket. Lastly, import data by running the following comma...
athe effect of p53 DBMs mutations on survival and therapeutic response should be analyzed in ongoing or planned clinical trials to confirm or exclude their more aggressive nature under particular clinical settings. 在持续或计划的临床试验应该分析p53 DBMs变化的作用在生存和治疗反应精读firm或排除他们...
Yes. One suggestion is the reduction of synchronous processing in the Control Flow. When you want to introduce a data-staging environment, it’s natural to first pick up the data from the source and land it to a staging environment, and then pick the data back up from the staging environm...
数据库安全与操作系统安全密不可分 如果多级安全 DBMS 的安全策略不违反 OS 的安全策略 那么可 以使用多级安全 OS 的安全机制来实现 DBMS 的部分安全功能 如强制访问控制 . 信息流分析使我们能更好地理 解安全策略的意义和内容 . 该文给出了多级安全 OS 模型和以该模型为基础的多级安全 DBMS 模型 首次详细分...
