- In unit eight, we are introduced to advanced database topics. In typical client–server systems the server machine is much more powerful than the clients; that is, its processor is faster, it may have multiple processors, and it has more memory and disk capacity. Consider instead a scenario where client and server machines have exactly the same power. Would it make sense to build a client–server system in such a scenario? Why? Which scenario would be better suited to a data-server architecture? Database systems are in use everywhere in our society. Explain the advantages of cloud computing over the traditional IT model (Table 10.1) and reference 2 additional websites.In the context of distributed file systems, compare and contrast NFS (Network File System) and HDFS (Hadoop Distributed File System). What are their strengths and weaknesses for different use cases?The conversion of requests to outcomes across the internal, external, and conceptual levels of a three-schema architecture is referred to as
- Explain what is the main purpose for creating this OSI Reference Model? Why it is a layered model?Describe the CAP theorem (Consistency, Availability, Partition Tolerance) and its implications in distributed systems design. How do different system models trade off these three aspects?In distributed database systems, which is preferable: data replication or data fragmentation? Could we mix fragmentation and replication, in your opinion? How distinct are the two types of fragmentation, vertical and horizontal? Could you provide me an illustration of your point?
- Describe a scenario in a NoSQL database where data can be at rest, in use, and in motion at the same time. Refer to the architecture diagrams for one of the NoSQL database systems covered in the lecture slides.Why and how should dynamic scoping be used? What are the performance implications of using dynamic scoping?What is dynamic scoping, when and where is it used, what are the performance costs associated with dynamic scoping, and how may these costs be minimised?
- What is dynamic scoping, when and where it is applied, what are the performance impacts of using dynamic scoping and how can these be minimized?Consider a database system based on a client-server architecture, with the server acting as a data server. A. What is the effect of the speed of the interconnection between the client and the server on the choice between tuple and page shipping? B.. If page shipping is used, the cache of data at the client can be organized either as a tuple cache or a page cache. The page cache stores data in units of a page, while the tuple cache stores data in units of tuples. Assume tuples are smaller than pages. Describe one benefit of a tuple cache over a page cache.In distributed database systems, which is preferable: data replication or data fragmentation? Is it possible, in your opinion, to combine the processes of fragmentation and replication? Can we differentiate between vertical and horizontal fragmentation? Could you provide me an illustration of your point?
