Influence of Structured, Semi-
Structured, Unstructured data on
various data models
Shagufta Praveen, Research Scholar, Umesh Chandra, Assistant Professor
Glocal University,
Abstract: Enormous growth of data from diversified sources changed the complete scenario of database world. Most of the
surveys say that data is very important for all the organizations and its proper handling will seek attention in future. Various forms of
data available in the digital world need different data models for their storage, processing and analysis. This paper discusses
various kinds of data with their characteristics with examples, and also represents that the growing data is responsible for the
numerous emerging data models and database evolution.
Keywords: Structured, Unstructured, Semi structured, Data Models
1. Introduction:
Big Data is a term that catches attention of everyone
today. This attention can be justified through some
surveys and facts. These surveys and facts says that
each and every second we all users are creating a new
data which gives a addition to the rate of data
growth. Most of the web applications like Facebook,
Twitter, Instagram, Youtube are the ones which
connects with 1 billion people every day and these
people not only survey but share and create new data
every single second [1]. Survey says that the amount
of digital universe will double in every two years [2].
Most of the organizations are working on data driven
projects [3]. Most of the organization doesn’t consider
web data as dead data where as different research
center using this data for analysis purpose and trying
to utilize it for business intelligence and pattern
prediction. Data mining and data extraction deals
with various algorithms to extract data so that it
could help us for betterment in IT industries.

2.1. Structured data:
Structured data includes mainly text, these data are
easily processed. These data are easily entered, stored
and analyzed. Structured data are stored in the form
of rows and columns which is easily managed with
the a language called “structured query
language”(SQL)[4].Relational model[5] is a data
model that supports structured data and manage it in
the form of row and table and process the content of
the table easily. XML also
Support structured data. Most of the content of the
web pages are in the XML forms. These content are
included in structured data, companies like Google
uses structured data to find on the web to understand
the content of the page [6]. This way most of the
Google search is done with the help of structured
data. Since starting of the revolution of database[7]
network[8], hierarchical[9], relational, object
relational[10] data model deals with structured data.
2.2. Characteristics of
Structured Data
1. Structured data has various data type: date, name,
number, characters, address
2. These data are arranged in a defined way
3. Structured data are handle through SQL
4. Structured data are dependent on schema, it is a
schema based
5.These data can easily interact with computer
2.3.Semi-Structured Data
Semi-structured data includes e-mails, XML and
JSON. Semi structured data is not fit for relational
database where it is expressed with the help of edges,
labels and tree structures. These are represented with
the help of trees and graphs and they have attributes,
labels. These are schema-less data. Data models
which are graph based can store semi-structured data.
MongoDB is a NOSQL model that support JSON
(semi-structured data).
Data consist of tags and which are self-describing are
generally semi-structured data. They are different
from structured and unstructured data. Data object
Model [11], Objects Exchange Model [11], Data
Guide[11] are famous data model that express semi-
structured data. Concepts for semi-structured data
model: document instance, document schema,
elements attributes, elements relationship sets[11].
Fig.3 Attributes of Semi-Structured
Data
2.4.Example of Semi-structured Data
{
Row:{Emp_id:” 12345”,Emp_name:”Ram”},
Row:{Emp_id:” 56786”,Emp_name:”Hari”},
Row:{Emp_id:” 67858”,Emp_name:”Shyam”},
Row:{Emp_id:” 90890”,Emp_name:”John”},
}
2.5. Characteristics of Semi-structured
Data
1. It is not based on Schema
2. It is represented through label and edges
3. It is generated from various web pages
4. It has multiple attributes

3. Unstructured Data
Unstructured data includes videos, images, and
audios. Today, in our digital universe 90% of data
which is increasing is unstructured data. This data is
not fit for relational database and in order to make
them store, scenario came up with NoSQL database.
Today there are four family of NoSQL database: key-
value, column-oriented, graph-oriented, and
document-oriented. Most of the famous organization
today(Amazon, linkedln, Facebook, Google, Youtube)
is dealing with NoSQL data [12 ] and they are
replaced their convention database to NoSQl
database.
3.1.Characteristics of Unstructured
Data
1. It is not based on Schema
2. It is not suitable for relational database
3. 90% of unstructured data is growing today
4. It includes digital media files, Word doc.
,pdf files,
5. It is stored in NoSQL database
Fig.4. Attributes of Unstructured Data
Fig.5. Example of Unstructured Data
4. Conclusion: This paper emphasize on
the concept that growing data directly
influence its related data models and
database technologies, it represents that big
data concept not only deals with huge and
vast data but it gives a new gate to database
analyst and researchers to work on various
data and data models for survival of new
kinds of data in upcoming and present
scenario.
