resulting in data loss. RAID allows you to survive a drive loss without data loss and in many cases without any downtime. 3. RAID 0 - Never‚ unless the data has no value to you. RAID 1 - If you are looking to inexpensively gain additional data redundancy and/or read speeds. A good base RAID level for those looking to achieve high uptime. RAID 5/6 - Web servers and high read environments. Generally will perform worse than RAID 1 on writes‚ so if your environment is write heavy or you don’t need

How to communicate effectively about redundancy When it comes to dealing with redundancies within a firm‚ internal communication is often neglected. But this should always be a priority‚ because it creates engagement‚ and engagement is crucial to productivity. During and after restructures‚ it becomes even more important.

Data Ware House Normalization it’s a process of splitting data into 2 or more entities to reduce data redundancy. Normal Forms: 1. A database table must contain no repeating groups 2. All non-key attributes of a table must rely on the entire key of the table. 3. All non-key fields must depend solely on the table’s primary key. First Business Normal Form: removes repeating groups to another entity. This entity takes its name and primary (compound) key attributes‚ from the original entity and forms

RAID can be used when there’s a lot of important data that we are constantly changing and need to back up often. 3. Define the following types of RAID: a. RAID 0- Has Stripped Blocks and has no Redundancy. Has to have two disks b. RAID 1- Is a mirrored blocks and is the best performance of the four because it isn’t striped and has no parity. It also needs two drives. c. RAID 5- It has striped blocks that spreads across three or more disks. d. RAID 6- RAID 6 is RAID 5 except it can recover
