### RDBMS Interview questions

RDBMS Concepts

1. What is database?

A database is a logically coherent collection of data with some inherent meaning, representing some aspect of real world and which is designed, built and populated with data for a specific purpose.

2. What is DBMS?

It is a collection of programs that enables user to create and maintain a database. In other words it is general-purpose software that provides the users with the processes of defining, constructing and manipulating the database for various applications.

3. What is a Database system?

The database and DBMS software together is called as Database system.

4. Advantages of DBMS?

? Redundancy is controlled.

? Unauthorised access is restricted.

? Providing multiple user interfaces.

? Enforcing integrity constraints.

? Providing backup and recovery.

5. Disadvantage in File Processing System?

? Data redundancy & inconsistency.

? Difficult in accessing data.

? Data isolation.

? Data integrity.

? Concurrent access is not possible.

? Security Problems.

6. Describe the three levels of data abstraction?

The are three levels of abstraction:

? Physical level: The lowest level of abstraction describes how data are stored.

? Logical level: The next higher level of abstraction, describes what data are stored in database and what relationship among those data.

? View level: The highest level of abstraction describes only part of entire database.

7. Define the "integrity rules"

There are two Integrity rules.

? Entity Integrity: States that "Primary key cannot have NULL value"

? Referential Integrity: States that "Foreign Key can be either a NULL value or should be Primary Key value of other relation.

8. What is extension and intension?

Extension -

It is the number of tuples present in a table at any instance. This is time dependent.

Intension -

It is a constant value that gives the name, structure of table and the constraints laid on it.

9. What is System R? What are its two major subsystems?

System R was designed and developed over a period of 1974-79 at IBM San Jose Research Center. It is a prototype and its purpose was to demonstrate that it is possible to build a Relational System that can be used in a real life environment to solve real life problems, with performance at least comparable to that of existing system.

Its two subsystems are

? Research Storage

? System Relational Data System.

10. How is the data structure of System R different from the relational structure?

Unlike Relational systems in System R

? Domains are not supported

? Enforcement of candidate key uniqueness is optional

? Enforcement of entity integrity is optional

? Referential integrity is not enforced

11. What is Data Independence?

Data independence means that "the application is independent of the storage structure and access strategy of data". In other words, The ability to modify the schema definition in one level should not affect the schema definition in the next higher level.

Two types of Data Independence:

? Physical Data Independence: Modification in physical level should not affect the logical level.

? Logical Data Independence: Modification in logical level should affect the view level.

NOTE: Logical Data Independence is more difficult to achieve

12. What is a view? How it is related to data independence?

A view may be thought of as a virtual table, that is, a table that does not really exist in its own right but is instead derived from one or more underlying base table. In other words, there is no stored file that direct represents the view instead a definition of view is stored in data dictionary.

Growth and restructuring of base tables is not reflected in views. Thus the view can insulate users from the effects of restructuring and growth in the database. Hence accounts for logical data independence.

13. What is Data Model?

A collection of conceptual tools for describing data, data relationships data semantics and constraints.

8. Oracle cursor : Implicit & Explicit cursors

Oracle uses work areas called private SQL areas to create SQL statements.

PL/SQL construct to identify each and every work are used, is called as Cursor.

For SQL queries returning a single row, PL/SQL declares all implicit cursors.

For queries that returning more than one row, the cursor needs to be explicitly declared.

9. Explicit Cursor attributes

There are four cursor attributes used in Oracle

cursor_name%Found, cursor_name%NOTFOUND, cursor_name%ROWCOUNT, cursor_name%ISOPEN

10. Implicit Cursor attributes

Same as explicit cursor but prefixed by the word SQL

SQL%Found, SQL%NOTFOUND, SQL%ROWCOUNT, SQL%ISOPEN

Tips : 1. Here SQL%ISOPEN is false, because oracle automatically closed the implicit cursor after

executing SQL statements.

: 2. All are Boolean attributes.

A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes

in one direction and the hare in the other. The hare starts after the tortoise has covered

1/5 of its distance and that too leisurely. The hare and tortoise meet when the hare has

covered only 1/8 of the distance. By what factor should the hare increase its speed so as

to tie the race?

Planet fourfi resides in 4-dimensional space and thus the currency used by its residents

are 3-dimensional objects. The rupee notes are cubical in shape while their coins are

spherical. However the coin minting machinery lays out some stipulations on the size of

the coins.

The diameter of the coins should be at least 64mm and not exceed 512mm.

Given a coin, the diameter of the next larger coin is at least 50% greater.

The diameter of the coin must always be an integer.

You are asked to design a set of coins of different diameters with these requirements and

your goal is to design as many coins as possible. How many coins can you design?

Alok and Bhanu play the following min-max game. Given the expression

N = 12 + X*(Y - Z)

where X, Y and Z are variables representing single digits (0 to 9), Alok would like to

maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a

single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z).

Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally

Alok proposes the value for the remaining variable. Assuming both play to their optimal

strategies, the value of N at the end of the game would be
