SQL vs NoSQL, Structured Query Language (SQL)
More rigid and structured way of storing data
Consists of two or more tables with columns and rows
Relationship between tables and field types is called a schema
A well-designed schema minimizes data redundancy and prevents tables from becoming out-of-sync.
NoSQL: Not only SQL
Greater flexibility than their traditional counterparts
Unstructured data from the web
NoSQL databases are document-oriented
Ease of access
Modern databases and its challenges (SQL ,NoSQL, NewSQL)Mohamed Galal
Nowadays the amount of data becomes very large, every organization produces a huge amount of data daily.
Thus we want new technology to help in storing and query a huge amount of data in acceptable time.
The old relational model may help in consistency but it was not designed to deal with big data problem.
In this slides, I will describe the relational model, NoSql Models and the NewSql models with some examples.
An perspective into the raise of NoSQL systems and an comparison between RDBMS and NoSQL technologies.
The basic idea of the presentation originated while trying to understand the different alternatives available for managing data while building a fast, highly scalable, available, and reliable enterprise application.
SURVEY ON IMPLEMANTATION OF COLUMN ORIENTED NOSQL DATA STORES ( BIGTABLE & CA...IJCERT JOURNAL
NOSQL is a database provides a mechanism for storage and retrieval of data that is modeled for huge amount of data which is used in big data and Cloud Computing . NOSQL systems are also called "Not only SQL" to emphasize that they may support SQL-like query languages. A basic classification of NOSQL is based on data model; they are like column, Document, Key-Value etc. The objective of this paper is to study and compare the implantation of various column oriented data stores like Bigtable, Cassandra.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. ORACLE HISTORY
Larry Ellison and his two friends and former co-workers, Bob Miner and
Ed Oates, started a consultancy called Software Development
Laboratories (SDL) in 1977. SDL developed the original version of the
Oracle software.
Developer
Usage
Oracle Database Architecture. An Oracle database is a collection of data treated
as a unit. The purpose of a database is to store and retrieve related
information. A database server is the key to solving the problems of information
management.
The i in oracle 8i and 9i stands for INTERNET and the g in 10g and 11g stands for
GRID, because from 10g onwards oracle supports grid architecture.
Meaning of i & g in Oracle databases
Oracle released Oracle Database 12c into general availability July 1, 2013.
According to Oracle, this is "the first database designed for the cloud.”
Meaning of Oracle 12c

Note: If running on one of the above releases, it is
recommended to always install the latest patch-set.
5. OVERVIEW OF ORACLE GRID ARCHITECTURE
Grid computing is a new IT architecture that produces more resilient and lower cost enterprise information
systems. With grid computing, groups of independent, modular hardware and software components can
be connected and rejoined on demand to meet the changing needs of businesses.
Benefits of Grid Computing
Compared to other models of computing, IT systems designed and implemented in the grid style deliver
higher quality of service,
lower cost, and
greater flexibility.
Higher quality of service results from having no single point of failure,
a robust security infrastructure, and
centralized, policy-driven management.
Lower costs derive from increasing the utilization of resources and dramatically reducing
management and maintenance costs.
Rather than dedicating a stack of software and hardware to a specific task, all resources are
pooled and allocated on demand, thus eliminating under utilized capacity and redundant capabilities.
Grid computing also enables the use of smaller individual hardware components, thus reducing the cost
of each individual component and providing more flexibility to devote resources in accordance with
changing needs.

11. DATABASE STRUCTURE
Logical structure - maps the data to the Physical
structure.
Physical structure -part of the operating system’s file
structure.
Memory structure - where all the processing takes
place.
12. THE LOGICAL STRUCTURES
control how the data must be stored in
the database.
five Logical structures:
tablespaces
segments
extents
data blocks
schema objects
14. TABLESPACES
A database is divided into logical storage units
called Tablespaces.
logical construct for arranging different types
of data
An Oracle database must have at least a
system tablespace.
It is recommended to have different
tablespaces for user and system data.
16. DATA BLOCKS
The smallest unit of Input/Output used by Oracle
database.
The size of data block for any database is fixed at the
time of creation of the database;
Some values of the data block size are 2KB, 8KB,
16KB, and 32KB.
Oracle recommends a size of 8KB
17. EXTENTS
The next level of data storage.
One extent consists of a specific number of
data blocks
One or more extents in turn make up a
segment.
When the existing space in a segment is
completely used, Oracle allocates a new
extent for the segment.
18. SEGMENT
A segment consists of a set of extents
Each table’s data is stored in its own single
segment.
Each index’s data is stored in a single
segment.
More extents are automatically allocated by
Oracle to a segment if its existing extents
become full.
The different types of segments are the data
segments, index segments,rollback segments,
and temporary segments.
19. PHYSICAL DATABASE STRUCTURE
Password file - which contain the password
information for all users.
Parameter file - which contains all the important
information necessary to start a database.
Datafiles - which contain the application data
being stored, as well as any data necessary to
store user-IDs, passwords, and privileges.
Redo log files - which store all the transactions
made to the database. These files are also
called transaction log files.
Control files - which store information
specifying the structure of the database,such
as the name and time of creation of the
database and the name and location of the
21. DATA ACCESS: SQL
Data definition language (DDL) statements
Data manipulation language (DML)
statements
Transaction control statements
Session control statements
System control statements
Embedded SQL statements
22. TRANSACTIONS
A transaction is a logical unit of work that comprises
one or more SQL statement executed by a single
user. According to the ANSI/ISO SQL standard, with
which Oracle is compatible, a transaction begins with
the user’s first executable SQL statement. A
transaction ends when it is explicitly committed or
rolled back.
24. DATA ACCESS: SQL
Session Control Statements
These statements let a user control the properties of the current
session, including enabling and disabling roles and changing language
settings. The two session control statements are
ALTER SESSION and SET ROLE.
System Control Statements
These statements change the properties of the Oracle database
instance. The only system control statement is ALTER SYSTEM.
It lets users change settings, such as the minimum number of shared
servers, kill a session, and perform other tasks.
Embedded SQL Statements
These statements incorporate DDL, DML, and transaction control
statements in a procedural language program, such as those used with
the Oracle precompilers. Examples include OPEN,
CLOSE, FETCH, and EXECUTE
25. Overview of Data types
Each column value and constant in a SQL statement has a data
type, which is associated with a specific storage format,
constraints, and a valid range of values. When you create a table,
you must specify a datatype for each of its columns.
Oracle provides the following built-in data types:
Character datatypes
Numeric datatypes
DATE datatype
LOB datatypes
RAW and LONG RAW datatypes
26. Relational Model Concepts
A Relation is a mathematical concept based on
the ideas of sets
The model was first proposed by Dr. E.F. Codd of
IBM Research in 1970 in the following paper:
– "A Relational Model for Large Shared Data Banks," Communications of
the ACM (Association for Computing machinery), June 1970
The above paper caused a major revolution in the
field of database management
27. FUNCTIONS OF A DBMS
Data definition: SQL lets a user define the structure and organization
of the stored data and relationships among the stored data items.
Data retrieval: SQL allows a user or an application program to retrieve
stored data from the database and use it.
Data manipulation: SQL allows a user or an application program to
update the database by adding new data, removing old data, and
modifying previously stored data.
Access control: SQL can be used to restrict a user’s ability to retrieve,
add, and modify data, protecting stored data against unauthorized
access.
Data sharing: SQL is used to coordinate data sharing by concurrent
users, ensuring that they do not interfere with one another.
Data integrity: SQL defines integrity constraints in the database,
protecting it from corruption due to inconsistent updates or system
failures.
SQL is thus a comprehensive language for controlling and interacting
with a database management system.
28. Informal Definitions
Informally, a relation looks like a table of values.
A relation typically contains a set of rows.
The data elements in each row represent certain facts
that correspond to a real-world entity or relationship
– In the formal model, rows are called tuples
Each column has a column header that gives an
indication of the meaning of the data items in that column
– In the formal model, the column header is
called an attribute name (or just attribute)
30. Relational Integrity Constraints
Constraints are conditions that must hold on all
valid relation states.
There are three main types of constraints in the
relational model:
– Key constraints
– Entity integrity constraints
– Referential integrity constraints
Another implicit constraint is the domain
constraint
– Every value in a tuple must be from the domain of its attribute (or it
could be null, if allowed for that attribute)
31. STRUCTURED QUERY LANGUAGE
SQL (Structured Query Language) is a database sub-language for
querying and modifying relational databases.
It was developed by IBM Research in the mid 70's and standardized by
ANSI in 1986.
Relational Model defines two root languages for accessing a relational
database -- Relational Algebra and Relational Calculus.
