The rule for first normal form (1NF) is a table in which the intersection of every column and record contains only one value. In other words a table that contains more than one atomic value in the intersection of one or more column for one or more records is not in 1NF. The non 1NF table can be converted to 1NF by restructuring original table by removing the column with the multi-values along with a copy of the primary key to create a new table. See Figure 8.4 for an example of this approach.…

volume of data that needs to be scanned. When the query is too complex, the optimizer is no longer able to determine an optimal method and resorts to whole table scans to find the desired records, ignoring the indexing. A whole table scan on a moderate-sized table may take only seconds, but on the very large tables found in data warehouses, it can take several minutes. And when performing a complex query that involves many tables and many indices on those tables, whole table scans can force a…

This statement means that bullying should not be a narrative for physical aggression only. In addition, there are different forms of aggressions that bullies can use to inflict harm or hurt on their victim. Furthermore, bullying can be difficult to identify and differentiate the forms of aggressions.…

Another kind of hurtful bystander is someone who encourages the bully by reacting positively to their actions, like laughing, cheering, or shouting encouragement (Education Development Center, 2008). This kind of bystander is also a bully. By encouraging it to happen, they are participating in the bullying. The more bystanders who do this, the worse it gets. Bystanders who do this should be held to the same standards as the bully when it comes to punishment, because their actions are equally bad…
