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.

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”.

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.

2. TYPES OF INFORMATION SYSTEMS
Transaction processing systems
Management information system and
decision support systems
Executive support system for senior management
3. Transaction processing system
Transaction processing system is a type of information system
. TPSs collect, store, modify and retrieve the transactions of an
organization, A Transaction is an event that generates or
modifies data that is eventually stored an information system.
E.g : Order entry system, cheque processing systems,
accounts receivables systems, payroll systems and ticket
reservation systems
These systems help any company to conduct operations and
keep track of its activities

5. TPS CHARACTERISTICS
A TPS records internal and external transactions for a company. It is a
repository of data that is frequently accessed by other systems
A TPS performs routine , repetitive tasks .It is mostly used by lower
level managers to make operational decisions
Transactions can be recorded in batch mode or online.In batch mode
the files are updated periodically.In online mode , each transaction is
recorded as it occurs
There are six steps in processing a transaction.they are data entry
,data validation , data processing and revalidation , storage – output
generation and query support
6. Objectives of TPS
• Process data generated by and about transactions
• Maintain a high degree of accuracy and integrity
• Avoid processing fraudulent transactions
• Produce timely user responses and reports
• Increase labor efficiency
• Help improve customer service
• Help build and maintain customer loyalty
• Achieve competitive advantage
7. TYPES OF TPS
Online system:
it involves a direct connection between the operator and TPS
program , they provide immediate result eg . An order arrive by
telephone call it is processed at that moment and results are
produced
Batch processing:
it is the second type of TPS ,where transactions are grouped
together and processed as a unit
for eg: a cheque proccesing system in a bank all the cheque
received in a particular day are grouped together. They are
then sorted by the account no and processed in a batch
8. More Examples
Batch transaction processing:
Cheque clearance :written order asking bank to pay money to
a person
Bill generation : an invoice for general services provided to the
customers
credit card sales transaction
Examples of real time transaction processing:
reservation systems; set aside service/product for future use
point -of-sale (POS) terminals ;sells goods/services
library loan system ; keeps track of items borrowed from library
9. Difference between real time and
Batch
Real time:
each transaction is unique ; transactions are standlone;
requires master file to be available more often for
updating; fewer errors-transaction data is validated and
entered immediately; infrequent errors may occur; not
practical to shut down the whole system
Batch:
each transaction pat of a group; database not
accessible all of the time; more errors; data is organized
and stored before master file is updated -errors can
occur during these steps; easier to maintain than real-
time.
10. MIS
Designates a specific category of information systems
serving middle management.
Provides middle managers with reports on organization’s
current performance.
Information thus obtained is used to monitor and control
and business and predict future
11. Characteristics of MIS

18. Decision Support System
A decision support system (DSS) is a computer program application
that analyzes business data and presents it so that users can make
business decisions more easily. It is an "informational application"
(to distinguish it from an "operational application" that collects the
data in the course of normal business operation).Typical
information that a decision support application might gather and
present would be:
Comparative sales figures between one week and the next
Projected revenue figures based on new product sales assumptions
The consequences of different decision alternatives, given past
experience in a context that is described
A decision support system may present information graphically and
may include an expert system or artificial intelligence (AI). It may be
aimed at business executives or some other group of Knowledge
workers
19. Characteristics of Decision support system
Provides rapid access to information
Handles large amount of data from different sources
Provides report and presentation flexibility
Offer both textual and graphical orientation
Support drill down analysis
Perform complex ,sophisticated analysis aqnd
comparisons using advanced s/w
20. Activities in decision support system

22. DSS:Example
Voyage estimating system calculates financial and
technical voyage details. It is based on analytical
models.
Financial calculations include :
ship/time costs(fuel, labor, capital) ,freight rates for
various types of cargo and port expenses
Technical details include factor as:
ship cargo capacity, speed ,port distances ,fuel and water
consumption and loading patterns ( locations of cargo for
different ports
23. cont
The system can answer questions such as:
Given a customer delivery schedule and an offered
freight rate, which vessel should be assigned at what
rate to maximize profits?
What is the optimal speed at which a particular vessel
can optimize its profit and still meet its delivery
schedule?
What is the optimal loading pattern for a ship bound for
US west coast from Malaysia?
24. DSS : Intrawest(largest Ski operator in
north America
The system is not not model driven , focusing instead on
extracting useful information to support decision making
from massive quantities of data.
It uses special software to analyze these data to
determine the value , revenue potential and loyalty of
each customer so managers can make better decisions on
how to target their marketing programs
The system segments the customers into categories from
“passionate experts” to “ value – minded family
vacationers “ etc
The company then emails video clips that would appeal to
each segment to encourage more visits to its resort
25. EXECUTIVE SUPPORT SYSTEMS FOR SENIOR
MANAGEMENT
Issues at senior Management level:
What will employment be in 5 yrs ?
What are long term industry cost trends , where does our
firm fit in?
What products should we be making in next 5 yrs?
What new acquisitions would protect us from cyclical
business swings ?
26. Characteristics of ESS
Are tailored to individual executives
Are easy to Use
Have drill down abilities
Support the need for the external data
Can help with situations that have high degree of
uncertainty
Have a future orientation
Are linked with value added business processes
27. Role of ESS
• Addresses non routine decision requiring judgement , evaluation, and
insight
• Presents graphs and data from many sources through an interface that is
easy for senior managers to use
• Incorporates data about external events such as new tax laws or
competitors ,but also draws a summarized information from internal MIS
and DSS
• It filters ,compresses and track critical data , displaying that data of
greatest importance to senior managers.

Ensuring that no assets illegitimately exit that organization
39. Types of Accounting IS
General ledger systems
Asset Management
Order-entry system
Account receivables and payable system
Inventory control system
Payroll system
Cash management
40. Accounting Information Systems
The Accounting Information System (AIS) performs the firm’s accounting
applications . A high volume of data processing characterizes these applications .
Data processing consists of four major tasks – data gathering , data manipulation
, data storage , and document preparation
AIS is data oriented rather than information oriented , and the data is largely
historical
Although the AIS is data oriented, it does produce some information .In addition
, it provides the database that serves as the foundation for other CBIS
subsystems
41. Financial Information System
The term Financial Information System is used to describe the CBIS
subsystem
That provide information to persons and group both inside and outside
the firm concerning the firm’s financial matters . Information is provide
in the form of periodic reports , special reports , and results of
mathematical simulation , electronic communication , and the advice of
expert systems
A financial MIS provides financial information not only for executives
but also for a broader set of people who need to make better decision
on a daily basis. Financial MISs is used to streamline reports of
transactions.
42. Features of financial Information system

45. System Analysis and Design
The overall process by which information systems are designed
and implement within organizations is referred to as System
analysis and design ( SA &D).Within this process are contained
activities that include idedentification of business problems ;
the proposed solution , in the form of an information system
(IS ) , to one or more of the problems identified ; and the
design and implementation of that proposed solution to
achieve the desired and stared goals of the organization
46. The system development life cycle
One of the methods of using the systems approach to develop
information system solutions , and the most prevalent one in the
organization system analysis and design , can be viewed as multistep
, iterative process called the systems development life cycle (SDLC)

49. Systems analysis
System analysis is not a preliminary study; however it is an in
depth study of end user information needs that produces
functional requirements that are used as the basis for the design
of a new information system.System analysis traditionally
involves a detailed study of:
The information needs of a company and endusers like yourself
The activities , resources , and products of one or more of the
present information system being used
The information system capabilitiesrequired to meet your
information needs , and those of other business stakeholders
that use the system
50. Important steps for System analysis
Organizational analysis
Analysis of the present system
Logical analysis
Functional requirement analysis and
determination
51. Examples of Functional requirement for
proposed e commerce system for a business
Examples of Functional requirements
• USER FRIENDLY INTERFACE
• Automatic entry of product data and easy to use data entry
screens for web customers
• PROCESSING REQUIREMENTS
• Fast , automatic calculation of sales totals and shipping costs
• STORAGE REQIREMENTS
• Fast retrieval and update of data from product , pricing and
customer data base
• CONTROL REQUIREMENTS
• Signals for data entry errors and quick email confirmation for
customers
52. Eg of the functional requirements for the
proposed e commerce system
User interface requirement
Automatic entry of product data and easy to use data entry screens
for web consumers
Processing requirement
Fast, automatic calculation of sales totals and shipping costs
Storage requirements
fast retrieval and update of data from product , pricing , and
customer daabases
Control requirements
Signals for data entry errors and quick email conformation for
customers
53. System design
Once the analysis portion of the life cycle is complete , the
process of system design can begin . here is where the logical
model of the current system is modified until it represents
the blueprint for the new system.
Focus is on how the system will accomplish its objectives.
This is where issues related to hardware , software
, networking , data storage , security , and many others will
be discussed and determined .
As such system design consists of design activities that
ultimately produce physical system specifications satisfying
the functional requirements that were developed in the
system analysis process.

55. Useful guideline for the design of business
web sites
Remember the customers
Successful web sites are built solely for the customers, not to make
company VP happy
Aesthetics
Successful designs combine fast loading graphics and simple color palettes
for pages that are easy to read
Easy to navigate
Make sure it’s easy to et from one part of your site to another. Providing a
site map , accessible from every page
Searchability
Many sites have their own search engines , very few are actaully
useful.make sure yours is
Incompatibilities
A site that looks great on a PC using IE can often look miserable on an Ibook
running Netscape
Registartion forms
Registration forms are a useful way to gather customer data.But make your
customers fill out three page form and watch them flee
Dead links
Dead links are the bane of all web surfers – be sure to keep your links up
dated.many web design s/w tolls can now do tis for you
56. System Implementation
The system implementation stage involves hardware and
software acquisition , software development , testing of
programs and procedures , conversion of data resources , and a
variety of conversion alternatives.
It also involves the education and training of end users and
specialists who will operate a new system.
Implementation can be difficult and time consuming process ,
however it is vital in ensuring the success of any newly
developed system .Even a well designed system will fail if it not
properly implemented which is why the implementation
process typically requires a project management effort on part
of IT and business unit managers
