All databases tend to be normalized to some degree; in fact, a relational database almost must adhere to a minimum of 1NF to be useful. However, the more a database is normalized, the greater the impact of processing time of queries is likely to be. For one thing, higher levels of normalization results in larger numbers of decode tables and the like, requiring more table joins in retrieval queries and more referential integrity overhead.
Where the 'query tree' or 'algebra tree' is transformed using a set of predefined rules that will improve the queries performance. Performing the selections as early as possible to reduce load. It is a form of Query Processing.

Queries are done in a database.
The query wizard can only do a limited set of types of queries. There are some kinds of queries that it cannot create. Some kinds of queries can only be done in SQL. Union queries and data definition queries for example. It is more complicated to do queries in SQL, but you can do more powerful ones. The query wizard is just for simple queries or for getting a basic query which you can then enhance using the design grid or SQL.
No. Only your tables store data. Queries, Forms, Reports and Pages can just do things like display the data and manipulate it but, the data is always stored in the tables. When you run a query, open a report or a form, the data you see is ultimately coming from underlying tables. You can do queries on queries, or reports on queries or forms on queries but the original data always comes from the tables.
in databases what are the twi main fuctions of queries
A query in which the output is possibly infinite. This most often occurs in queries which are recursive or which contain negation. Such queries are disallowed by many database management systems to prevent unsafe queries.
The queries for which the result documents tend to concentrate on restricted time interval.
