II.Very Short Answer.

1.Define Data Model and list the types of data model used?

Data models define how the logical structure of a database is modeled.
Data models define how data is connected to each other and how they are processed and stored inside the system. The various data models are;

  1. Hierarchical Database Model,
  2. Network Model,
  3. Relational Model and
  4. Object-oriented Database Model.

2.List few disadvantages of file processing system.?

Data Duplication – Same data is used by multiple resources for processing, thus created multiple copies of same data wasting the spaces.
High Maintenance – Access control and verifying data consistency needs high maintenance cost.
Security – less security provided to the data.


3.What are the ACID properties ?

ACID Properties – The acronym stands for Atomicity, Consistency, Isolation and Durability. Atomicity follows the thumb rule “All or Nothing”, while updating the data in database for the user performing the update operation. Consistency ensures that the changes in data value to be constant at any given instance. Isolation property is needed during concurrent action. Durability is defied as the system’s ability to recover all committed actions during the failure of storage or the system.


4.What is SQL?


5.State few advantages of Relational data base?

  1. High Availability
  2. High Performance
  3. Robust TrAnswer:actions and support
  4. Ease of management
  5. Less cost


Part – C

III. Short Answer.

1.Explain on Evalution of DBMS ?

  1. The concept of storing the data started before 40 years in various formats.
  2. In earlier days they have used punched card technology to store the data.
  3. Then files were used. The file systems were known as predecessor of database system.
  4. Various access methods in file system were indexed, random and sequential access.
  5. The file systems has limitations like duplication, less security. To overcome this, DBMS was introduced.

2.Explain Types of SQL Commands?

Data Definition Language (DDL),
Data Manipulation Language (DML),
Data Query Language (DQL),
Action Control Language (TCL),
Data Control Language (DCL).


3.Discuss on cardinality in DBMS ?

Cardinality is defined as the number of items that must be included in a relationship, i.e. number of entities in one set mapped with the number of entities of another set via the relationship. Three classifications in Cardinality are one-to-one, one-to-many and Many-to-Many.

12th Computer Applications 2nd Assignment July 2021 Answerkey

In the above example we have two entities Person and Vehicle. If we consider the current vehicle, the driver is operating, then we have one-to-one relationship between Person and Vehicle.
In the above example, Customer places the Order is a one-to-many relationship. Here the customer can place multiple orders and the order is related to only one customer. The example of many-to-many relationship is Students registering the Courses. A student can register more than one courses and A course can be registered by many students. Hence it is many-to-many.


4.List any Five privileges available in mySQL for the User ?

Privileges:

  1. Select_priv
  2. Insert_priv
  3. Update_priv
  4. Delete_priv
  5. Create_priv
  6. Alter_priv

Action Performed (If Granted):

  1. User can select rows from database tables.
  2. User can insert rows into database tables.
  3. User can update rows of database tables.
  4. User can delete rows of database tables.
  5. User can create new tables in database.
  6. User can make changes to the database structure.


5.Explainthe DDI commands?

IV.Write in detail.

Discuss on various database models available in DBMS?

DBMS Database Models:
The database technology came into existence in terms of models with relational and object-relational behavior. The major database models are listed below:

(i) Hierarchical Database Model The famous Hierarchical database model was IMS (Information Management System), IBM’s first DBMS. In this model, each record has information in parent/child relationship like a tree structure. The collection of records was called as record types, which are equivalent to tables in relational model. The individual records are equal to rows.

12th Computer Applications 2nd Assignment July 2021 Answerkey

n the above model we have many advantages like less redundant data, efficient search, data integrity and security. This model also has few limitations like complex to implement and difficulty in handling many to many relationships.

(ii) Network model:
The first developed network data model was IDS (Integrated Data Store) at Honeywell. Network model is similar to Hierarchical model except that in this model each member can have more than one owner. The many to many relationships are handled in a better way. This model identified the three database components Network schema, Sub schema and Language for data management. Network schema – schema defines all about the structure of the database.
Sub schema – controls on views of the database for the user.
Language – basic procedural for accessing the database.
The major advantage of this model is the ability to handle more relationship types, easy data access, data integrity and independence. The limitation of network model is difficulty in design and maintenance.

(iii) Relational model:
Oracle and DB2 are few commercial relational models in use. Relational model is defined with two terminologies Instance and Schema.
Instance – A table consisting of rows and columns
Schema – Specifies the structure including name and type of each column.
A relation (table) consists of unique attributes (columns) and tuples (rows).

12th Computer Applications 2nd Assignment July 2021 Answerkey


(iv) Object-oriented database model:
This model incorporates the combination of Object Oriented Programming (OOP’s) concepts and database technologies.
Practically, this model serves as the base of Relational model. Object oriented model uses small, reusable software known as Objects.
These are stored in object oriented database.
This model efficiently manages large number of different data types. Moreover complex behaviors are handled efficiently using OOP’s concepts.

Discuss in detail on various types of attributes in DBMS?

Types of attributes:

  1. Key Attribute
  2. Simple Attributes
  3. Composite Attributes
  4. Single Valued Attribute
  5. Multi Valued Attribute

1. Key Attribute:
Generally a key attribute describes a unique characteristic of an entity.

2. Simple Attribute:
The simple attributes cannot be separated it will be having a single value for their entity. For Example: Let us consider the name as the attribute for the entity employee and here the value for that attribute is a single value.

3. Composite Attributes:
The composite attributes can be sub-divided into simple attributes without change in the meaning of that attribute. For Example: In the above diagram the employee is the entity with the composite attribute Name which are sub-divided into two simple attributes first and last name.

4. Single Valued Attributes:
A single valued attribute contains only one value for the attribute and they don’t have multiple numbers of values. For Example: Age- It is a single value for a person as we cannot given number of ages for a single verson, therefore it is a single valued attribute.
Attribute:

  1. Degree
  2. Bank_Account

Values:

  1. 3
  2. 85

5. Multi Valued Attributes:
A multi valued attribute has more than one value for that particular attribute. For example:
Degree – A person can hold n number of degrees so it is a multi-valued attribute.
In the below table are some examples for multi valued attributes.

Attribute:

  1. Degree
  2. Bank_Account

Values:

  1. B.TEch, MBA
  2. SBI, HDFC
