The following are some of the benefits of normalization:
removes redundancies
achieves consistency.
improves data accessing speed
improves the performance of the server
decreases time accessing from the database.
generally efficient working of the application
Normalization was introduced just to have CONSISTENT Data by avoiding REDUNDANCIES. While doing so, it introduces some overhead by having few new tables which definitely has an impact over PERFORMANCE and SPEED, because of involving many tables in the JOIN operation which itself proves the complexity. In short, you can prefer normalization for having Consistent and Clean Data with the cost of Performance and Speed.

What are the disadvantages of normalizing a table in a database?
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.
What is the means drop command?
The DROP table command of SQL lets you drop a table from database . The database requires you to empty a table before you eliminate from the database. But there is a condition for dropping a table ; it must be an empty table. syntax: 1st - delete from table-name; 2nd- drop table table-name;
Is a data table the same as a database?
No. A table is the primary object used within a database to store data. A typical database will consist of many tables.
What does the term table mean?
In database, Table refers to a structure which contains rows and columns. Data can be stored in these rows and columns in arranged manner.
What does the word table mean in database?
In a database, a table is a structured collection of data organized into rows and columns. Each row represents a unique record, while each column corresponds to a specific attribute or field of that record. Tables are used to store and manage data efficiently, allowing for easy retrieval, manipulation, and analysis through database queries. Essentially, they act like spreadsheets, but are designed for relational database management systems.

What are the importance of table form query in database?
In database system the data is stored in the form of table. So to store the data in the database, table are very important in a database system.
Why is a table created in database?
Tables are central to a database. A table stores the data. Everything else in the database, such as queries, forms and reports, use the data from the table. Without tables, a database is useless as it would have no data.Tables are central to a database. A table stores the data.

What virtual table in a database is known as a?
A view table.
What is RBDMS?
RDBMS stands for Relational Database Management System. RDBMS data is structured in database tables, fields and records. Each RDBMS table consists of database table rows. Each database table row consists of one or more database table fields.RDBMS store the data into collection of tables, which might be related by common fields (database table columns). RDBMS also provide relational operators to manipulate the data stored into the database tables. Most RDBMS use SQL as database query language.
What are the typical benefits of relational databases?
With a relational database, you can quickly compare information because of the arrangement of data in columns.A typical relational database has anywhere from 10 to more than 1,000 tables. Each table contains a column or columns that other tables can key on to gather information from that table.By storing this information in another table, the database can create a single small table with the locations that can then be used for a variety of purposes by other tables in the database. A typical large database, like the one a big Web site, such as the police would have, will contain hundreds or thousands of tables like this all used together to quickly find the exact information needed at any given time
Relationship between a database and a table?
A table is contained within the database and consists of columns and rows. A table is meant to store data and, in relational databases, are related to other tables within the same database.
What is example of partial dependency?
Partial dependency occurs in a database when a non-prime attribute is dependent on only a part of a composite primary key, rather than on the whole key. For example, in a table with a composite primary key consisting of StudentID and CourseID, if the attribute InstructorName is dependent only on CourseID, then this is a partial dependency. It indicates that the design can be improved by normalizing the database to eliminate such dependencies.
