Flexible grid optical networks (FONs) can accommodate diverse kinds of service connections with higher networking flexibility and spectrum-utilization efficiency by employing a finer resource allocation granularity (known as frequency slot) and a more sophisticated path-routing and resource-allocation algorithm (known as routing and spectrum assignment algorithm), when compared to the traditional...
A Data Warehouse (DW) is characterized by a huge amount of data centralized in a single database. This centralization has negative impacts on its performance especially for distributed companies; such us elevated storage cost, high query execution time and hard maintenance task. Since a relational data warehouse has the same physical structure as a classical database, it can enjoy all the benefits...
This paper illustrates an embedded database run in an ordinary embedded microprocessor, a description of the database structure and concrete operation methods. Based on this embedded database mechanism, insertion and deletion of data records can be achieved via the communications interface to the embedded microprocessor and all the data records can be inquired and modified via the human-machine interface...
