What does a sort mean in a database?
Sort refers to the action wherein the data fetched from a database table is ordered as per a specific criteria. The default order of sort is Ascending and the user can do a descending sort by using the keyword DESC after the order by keyword. Ex: select * from employee_details order by employee_num desc If the above statement is executed data will be displayed in descending order of employee numbers.
How is indexing faster than sorting when accessing data from a table?
Indexing can be faster than sorting. It can also be slower. It depends on how many rows your predicate clause is selecting, and on the data dispersion represented by those index keys. If you are selecting a few rows, such as less than 4% of the table, then by all means use an index. If you are selecting a lot of rows, such as more than 25% of the table, then the use of the index will usually degrade performance, so go for the full table scan followed by a sort. (Of course, now you are adding the use of sort space, so that is a consideration.) The break-even point depends on the particular RDBMS and on the structure of the data. If your RDBMS supports EXPLAIN PLAN, then use it, and learn to know what it means. Also, make sure you understand your data, because (sometimes) only you know the best way to query it, and it might make sense to override the optimzer and force a certain execution plan based on your knowledge.

When you sort data in a query the records in the underlying table are actually rearranged?
No. Most queries list off data, but does not affect the underlying data. Certain types of query can be used to change data in a table, but do not re-arrange the order of the data in the table itself. That is determined by the indexes, mainly the primary key. You can sort the data in the table itself and have it remain that way.
