The document describes the software development life cycle (SDLC) process. There are typically six stages in the SDLC: analysis, planning, design, coding, testing, and implementation & maintenance. The analysis stage involves identifying requirements, feasibility studies, and evaluating possible solutions. The design stage then further develops the logical and physical design based on requirements. Finally, the coding, testing, and implementation stages produce the final software product.

Normally Use Case Diagrams are used but the pictorial information in it is so small that an MS Word Table is sufficient. What is more it can also provide space for "Use Case Goal" which is very important for Use Case Modeling.
Tables are quick and easy to create and edit. No need to waste time to draw and label diagrams. One can still do it if necessary after creating the Use Case TABLE. Try.
A Use Case Table can spill over into multiple pages but a diagram cannot!
UML 2.5 allows TABLES to be used for diagrams. So, there is no compulsion to create diagrams spending a lot of time.

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.

3. The following project describes the internal processes that are common across all stages of the SDLC, and the third chapter describes the inputs, outputs, and processes of each stage. SYIT 191-200 2
4. Cont: There are six stages in SDLC: Analysis Planning Design Coding Testing Implementation & maintenance SDLC uses four main approaches viz. SYIT 191-200 3
7. Contemplative Questions What are the various approaches to developing Information Systems? Is there one best way? What is the difference between techniques, methodologies and tools? What does the popular term “SDLC” actually mean? SYIT 191-200 6
8. SDLC SDLC stands for Systems Development Life Cycle What does it mean? Why do we need it? SYIT 191-200 7
9. What is SDLC? SDLC stands for Systems Development Life Cycle First, SDLC is a Life Cycle. All systems have a life cycle or a series of stages they naturally undergo. The number and name of the stages varies, but the primary stages are conception, development, maturity and decline. The systems development life cycle (SDLC) therefore, refers to the development stage of the system’s life cycle SYIT 191-200 8
10. Approaches to Systems Development Process-Oriented Approach Focus is on flow, use and transformation of data in an information system Involves creating graphical representations such as data flow diagrams and charts Data are tracked from sources, through intermediate steps and to final destinations Natural structure of data is not specified Disadvantage: data files are tied to specific applications SYIT 191-200 9
13. Milestones Following are the milestones in SDLC – Requirement Gathering In this, customer needs are analysed in order to get a clear picture of the user requirements. If it is an existing system, requirements include improvement on the backlogs of the existing system. This is done by interviewing users and consultants of the the company (client). SYIT 191-200 12
14. Cont: Functional Specification It mentions, what functions is the product supposed to have i.e how the interface should be, what should the product do, how will the user use the product. SYIT 191-200 13
15. High Level Design (HLD) In this stage, logical view of the solution to customer requirements is arrived at. It helps in deciding operating systems, hardware, database design, architecture, security issues etc. SYIT 191-200 14
16. Low Level Design (LLD) In this phase, HLD is broken down into smaller modules/programs. LLD is used by developers. SYIT 191-200 15
20. 3.Rapid Application Development (RAD) Approach: Iterative Framework Type 4.Spiral Approach : combination of linear and iterative framework type
21. Waterfall Approach The Waterfall model is a sequential development approach, in which development is seen as flowing steadily downwards (like a waterfall) through the phases of requirements analysis, design, implementation, testing (validation), integration, and maintenance. Basic principles of the waterfall approach are: Project is divided into sequential phases, with some overlap and splashback acceptable between phases. Emphasis is on planning, time schedules, target dates, budgets and implementation of an entire system
22. Prototyping Approach Software prototyping, is the development approach of activities during software development the creation of prototypes, i.e., incomplete versions of the software program being developed. Basic principles of the Prototyping Approach are: Attempts to reduce inherent project risk by breaking a project into smaller segments and providing more ease-of-change during the development process. A basic understanding of the fundamental business problem is necessary to avoid solving the wrong problem.
24. Spiral Approach The spiral model. The spiral model approach is a software development process combining elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down aweigh consideration of project continuation throughout the life cycle. Focus is on risk assessment and on minimizing project risk by breaking a project into smaller segments and providing more ease-of-change during the development process, as well as providing the opportunity to evaluate risks
25. Rapid Application Development (RAD) Approach Rapid Application Development(RAD) is a software development methodology approach, which involves iterative development and the construction of prototypes. Rapid application development is a term originally used to describe a software development process introduced by James Martin in 1991. Standard systems analysis and design techniques can be fitted into this framework. Basic principles: Key objective is for fast development and delivery of a high quality system at a relatively low investment cost. Standard systems analysis and design techniques can be fitted into this framework.
27. Analysis Analysis is first phase in SDLC wherein the possible outcome of the software are discussed in detail. Analysis is similar to a patient visiting a doctor.Doctors always analyse their patient:observing,testing,questioning. SYIT 191-200 24
28. Analysis Phase Identify problem Feasibility study for new system Investigate current system Organisational & system goals Problems / limitations identified Possible solutions Evaluate all data collected Decision to continue
29.
30. Design Phase Hardware / Software to be used Suppliers selection Program specifications Screen design User interface Inputs Outputs Setting up Tests to be performed General Specifications for user documentation
32. Development Stages of the PDLC: Analyse Design Code Debug Test Document Implement Evaluate
33. Development Within he development phase there are various program development methodologies: RAD: Rapid Application Development Prototyping Waterfall model (traditional staged development) Agile model (Short bursts developing functional units of the project)
39. Question that need to be asked? Is there really a problem? If there is a problem, is it worth fixing? Like: Technical feasibility Economic feasibility Legal feasibility Operational feasibility Schedule feasibility SYIT 191-200 36
40. Analysis does not try to describe HOW the solution will work. A problem analysis will describe: required input (what data has to be acquired to produce the output?) required output (i.e. what information is the system supposed to produce?) Data and information should be described in detail. SYIT 191-200 37
71. Purpose of designing To transform the data model (developed in the analysis phase) into logical and physical information structure SYIT 191-200 46
72. Design user interface standards and guidelines The GUI standards and guidelines are based on the requirements for the user interface identified in the analysis phase. Standards are needed to ensure: consistency of the GUI of different parts of the application or system usability of the application (e.g. reducing error in using the application) maintainability SYIT 191-200 47
73. Design system architecture The technical architecture used by the application is described by presenting the various hardware, software and networking components, and their interfaces. SYIT 191-200 48
74. Design software components The design of functionality in Web applications include e.g. navigation (functionality of control buttons) control of windows (moving between frames, opening and closing of pop-up windows) data input (HTML forms, cgi data transfers) data processing output (dynamically created HTML pages) SYIT 191-200 49
75. Conclusion The structure imposed by this SDLC is specifically designed to maximize the probability of a successful software development effort. SYIT 191-200 50
