@zaasmi said in CS409 Assignment 1 Solution and Discussion: Question# 01: Scenario In today’s era of intelligence and mobility where every thing is shifted on mobile like mobile commerce, and mobile computing. Suppose you are working as DBA in a multinational company which works on mobile system and your company decided to change the database structure to embedded database, and as a DBA you suggest your company to used SQLite. State the reasons by which you will convince your company seniors to use SQL Lite? Solution: SQLite is file based and embeddable relational database management system. As it is lite and due to its support to relational database management system it is best to use in mobile applications. So, SQLite is very appropriate to construct an embedded database system. It is light database, and it is direct file system engine that uses SQL syntax, also doesn’t require a special database server or anything. Similarly, SQLite can easily adjust with the requirements of embedded system as it has small core, open source and database is a file which is very easy to apprehend the copy, move and cross platform sharing of database files. Now a days, SQLite use is increasing in embedded systems due to its advantages. SQLite will be more widely used in the embedded field, such as the remote control, intelligent mobile terminal, information appliances control, home medical equipment, mobile devices etc. In a multiplatform architecture SQLite having wide scope. Question # 02: Write any ten situations in which using SQLite will give best results? Solution: Embedded devices or applications Replacement for ad hoc disk files Stand-in for an enterprise database during testing or demos Multi-user applications Data analysis Application file format Server-side database Data transfer format Cache for enterprise data Internal or temporary database Websites File archive/ data container Education and Training Experimental SQL language extensions

CS409 Quiz 2 Solution and Discussion

Actually, there might be a bit of confusion in that interpretation. In the context of computer science and storage management exams (specifically regarding Data Center Management or Storage Area Networks), the question is usually asking which technology provides the highest performance and speed. The correct answer remains Array-based Migration. Why “None of the above” is incorrect in this context: While you are right that a prompt needs a clear question, in standardized testing for IT certifications (like EMC, NetApp, or VMware), this specific sentence structure is used to test your knowledge of migration overhead. Here is the technical comparison of why Array-based is the fastest: Host-based: Slowest because it consumes the host’s CPU/memory and moves data across the standard network. Appliance/Fabric-based: Fast, but requires an extra layer of hardware in the middle which can create a bottleneck. Array-based: Fastest because it moves data directly from one storage controller to another at the block level, usually over high-speed Fibre Channel links, with zero impact on the host or the application. If you are filling this out for a quiz, the system expects you to identify the most efficient technology from the list provided.
