RAID 0 – Disk Striping – Used for the storage of noncritical items but which requires fast read-write.– Does not have parity (parity is about checking whether the data has been lost or overwritten on transition)– Does not have redundancy or fault tolerance. i.e., when the drive dies, the data is lost. RAID 1 – Disk Mirroring – Used usually for OS, SQL Engine etc. installation– Two or more disks used to write data and is in parallel– High performance– High availability– No data loss on disk failure RAID 2 RAID 3 RAID 4 RAID 5 – Striping with Parity…

Write a program in a language of your choice to find the critical path from a given set of tasks. A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish. Each circle (A-G) are tasks with specific duration (in Hours). Input: Array of task names and duration given in the diagram. Output 1. Longest path (Critical path) is A+G+B+F+C+D (42Hrs)2. Shortest path is A+B+C+D (26 Hrs)

Well, the question is slightly wrong until the context is specified because it is possible to build Modern Data Warehouse by including Cosmos DB in the architecture. This is too much relevant today because the data is no more straight forward content with human readable entities and relations (structured), but unstructured and/or streaming too. Also the pace of the data flow, or business requirement is becoming near real-time. See a reference architecture below: Image Source: MS Docs Here, in this blog, the context is about Traditional Data Warehouse possibility, where you will be modelling the data, specifying relationships, etc. Let…
