1 RUNNING HEAD: Holism versus Reductionism Holism versus Reductionism Yashwanth Reddy Aluguvelli Wilmington University 2 RUNNING HEAD: Holism versus Reductionism Abstract The objective of this paper is to examine the concepts of holism and reductionism as they relate to System Dynamics (SD) and to a lesser extent Systems Thinking (ST) then to relate the findings of that examination to some of the disillusionment with System Dynamics and the resultant lack of commercial take up. This paper deals in wide range of academic areas starting from medicine to philosophy related to the concepts of Holism and Reductionism according to the system dynamics literature. Practical applications of Reductionist and Holistic principles are examined. From this examination the basic way of System Dynamics as an all holistic/Reductionist approach is concluded and separated from the all the more by and large all holistic nature of Systems Thinking. It can be concluded that though system dynamics methodology is not necessarily described by practitioners, it is a reductionist methodology. The paper recommends that there be further work carried out in the field of theoretical and practical holism and greater awareness of these issues within the practitioner community. Within the conclusions there is a pointer for some further fundamental areas of work. Keywords: \"System Dynamics\1 Running Head: System Development Life Cycle System Development Life Cycle Yashwanth Reddy Aluguvelli Wilmington University 2 Running Head: System Development Life Cycle Abstract SDLC is multiple and iterative process which is very essential cycle for a system to perform each and every step in project development. This gives an easy way to an organization to development the project with most suitable model of SDLC. SDLC is involved in implementation, process, control of the project. Hence, it plays a major role in project development. Since, many kinds of projects are developed now-a-days; the SDLC is also growing with many models introduction. Traditionally, SDLC is defined in five stages or phases, but now it is being varied from four stages to twelve stages. Among all those models, two models of SDLC are going to be discussed in this paper. Seven step SDLC model and four step SDLC models are explained in detailed in this paper. These two models are further compared and which is better for a system is checked. The conclusion is given on the basis of features and comparison results between both models. This paper enables one to identify each and every prospective of the models and hence concludes which one is better option among the both. Keywords: SDLC model, Seven step SDLC model, Four step SDLC model. Seven Step SDLC Model The seven step SDLC model is now widely used in a system now-a-days. This process is most detailed and involves keen observation of the project development. The steps involved in this model are named as: 1. 2. 3. 4. 5. 6. 7. Planning Systems Analysis and requirements System Design Development Integration and Testing Implementation Operations and Maintenance 3 Running Head: System Development Life Cycle 1. Planning: Planning is the basic step that every SDLC has. It is the first and fore most step that is to be performed for a project development. In this stage, each and every requirement for the project development are mentioned and listed in a document including project cost, problems and solutions while project is under process and many more. This document is submitted to the higher officials in the organization such as stakeholders, who give financial support to the project development. This document is generally termed as business case for a project. The whole process of project development is mentioned step by step accurately. 2. System Analysis and Requirements: Here the total project will be analyzed and problems or errors in the project development are sorted out. The solutions for those problems are given and hence make the development process more effective. If there is a need of change of any functionalities or operations of the project, the changes are made and implies more better project. There are several tools for the making changes and creating solutions for the problems. Some of the most common tools that we use in the project development are: CASE (Case Aided Systems/Software Engineering) Requirements gathering Structure Analysis 3. System Design: Designing of a project is the most essential part in the project development. The detailed information about the features and operations of the proposed system are mentioned. They are designed as per the requirements specified in the planning document. The users' or employees' and stakeholders' discussions and meetings on the proposed project will come to an end in this stage as the total components such as hardware and software are confirmed at this stage. This step is the basic stage for the 4 Running Head: System Development Life Cycle further development of the project and helps in developing the project to the better and best level of the proposed system. 4. Development: This is where the real process of project development starts. In this step, the components and requirements specified are further developed for the complete system. Programmer, network employee and database developer play the major role in this development stage as programming and storage and web services of the desired system should be ensured. This is the major task of the whole process of project development. In this stage, the process is put into a flow chart to ensure the development is organized in correct way. The production of the project starts at this stage and involves most of installation and change of programming according to the project requirements is done. There is a huge benefit to the organization in this stage, as the training of the employees will also be included in this stage. 5. Integration and Testing: The integration and testing is the checking process of the project after development. Here, the errors in the project development are sorted and verified and further rectified by creating solutions for those problems accordingly. The integration is performed to check whether the project meets the required level or not and on the other side, the verification and validation tasks are performed in order to make sure that the project is successfully completed or not. 6. Implementation: Here, the major work such as writing code for the project and installation of newly developed project is performed. This enhances the production by transferring the modified components from old system to the new system. This stage gives the new project by reducing the risk to the project working and the project is to be realized by system analysts and users for implementation of the project. 5 Running Head: System Development Life Cycle 7. Operations and Maintenance: This is the final stage of the project/system development life cycle and this stage performs the action of maintenance and upgrading the project to boost the performance of the system. Four Step SDLC Model The 4 step SDLC model contains all the operations for the system development in only four steps. This model is very complex inner because it contains all the seven step operations in only four steps. The best example for four step SDLC model is Spiral Model. This model of SDLC is used mostly for larger projects involving constant enhancements because it is a combination of both the sequential as well as prototype model and performs larger tasks in shorter span. There are some projects with large software program part but developed for small outputs where spiral model is used and gave good results. The four phases/stages/steps of spiral model are: 1. Planning Phase 2. Risk Analysis Phase 3. Engineering Phase 4. Evaluation Phase 1. Planning Phase: As similar to that of the seven step model, planning phase of four step model also gathers all the information about the project development. The document such as business case is prepared by mentioning the process of the development along with the requirements. This enhances feasibility of study of the project development and the review of the overall objectives of the development results in better planning and helps to overcome the drawback in the process as mentioned in the document. This helps in finalizing the list of requirements for the project output also. 2. Risk Analysis Phase: 6 Running Head: System Development Life Cycle The risk analysis phase refers to the analysis of the total project development and checks whether there are any problems or errors may occur during the development. If there are chances for occurrence of the problems or errors, certain solutions for expected problems are found and kept for the use when problems occur. Once the risks or problems occur, the reduction and prevention strategy is planned and according to it the risk is either completely eliminated or mitigated. This phase plans a documentation specifying all the risks or errors as well as their solutions. This document clearly specifies each and everything that is carried in this stage and the appropriate methods and rectifications are performed accordingly. 3. Engineering Phase: The engineering phase is nothing but the real time work of the project development. In this phase, the development process of the project takes place and gives the output and further subjects for an evaluation process. The development process includes installation of some software tools and developing the project with the help of them. The software tools are generally used for coding the program for the project and implementing it with or without the help of hardware. We some cases use hardware part, when a product (such as mobile phones, gadgets, etc.) is subjected to development. The hardware is not necessary in case web application development and other only software based programs. Once the coding process is completed, the developed project model is then taken test. Based on the test results, the developed may be re-developed by overcoming the errors and drawbacks of the project when subjected to test. The components and other requirements of the old project are transferred into newly developed project and tested again. The final project is provided to the final review of the stakeholders along with the test summary and documents of each and every stage. 4. Evaluation Phase: 7 Running Head: System Development Life Cycle The evaluation phase is performed mostly by the customers and users who use the product/ project in future. The working, tools and other specifications of the project are checked, verified and evaluated in this phase. The feedback is generated on the basis of the project evaluation and hence released into the market according to the customer satisfaction. All the features of the project are documented and provided to the customer or user as user manual. Comparison between 7-step model and 4-step model The two models of SDLC are used to development of the project by using different stages and software tools based on the requirements of the project. But, among both the development methods, the seven step method is very useful and can be easily implemented for the development. The four step model is some more complex and difficult to develop a project as it has merged stages in the development process. The four step model is expensive than the seven step model and hence seven step model is mostly preferable model for the project development. The seven step model is time taking process, whereas, four step model is time saving process. But, seven step model is preferred because the four step development process cannot look over small issues in the project development and remained same causing some issues in the project while being used by the customers or users. Since the seven step model uses many steps for the development process and takes more time for each phase, the project after the complete development will be in a good working condition than that of the four step development method. Hence, by considering all the aspects of both the methods, I do believe that seven step SDLC model is more advantageous than four step SDLC model. Because, four step model has 8 Running Head: System Development Life Cycle intermediate stages and immediate documentation resulting in huge budget for the project. But, seven step model doesn't involve immediate documentation with intermediate stages and enhances the performance of the final project by concentrating more on the project for better results and this will be done in low cost and hence it is used mostly for the project development for ensuring the perfection of the project that is developed References Boehm.

This is very necessary for proper functioning of the system. The database backups are composed in different techniques for different level and requirements of usage. Disaster planning is a pre-planning for the system to create an easy recovery after being affected by the sudden and unexpected accidents. The disaster planning is the document used in many organizations now-adays. It is very necessary for an organization to contain a proper and well-designed planning documentary. This paper explains about the database backups and disaster planning. This paper also explains how important the integration of both the techniques is and also describes the clear view of the impact whether both the techniques are not executed properly. I look forward to give more information about both the techniques in detailed and clear. Keywords: Database backups, disaster planning, integration, impact Database Backup The database backup technique is very useful in retrieving the hidden, lost or old information in a system by setting up frequent backups of the system. The backups should be scheduled time-by-time to help in recovery of the system frequently. If the backups are run properly, then the restoring process will be easy and hence make the system more efficient in working. The backups are generally run for the purpose of getting back the data lost while virus is injected into the system, any sudden accident taken place, etc. There are various kinds of backups and database backup is one among those types. There can be two ways of database backups. They are: 1. SQL Database Backup 3 Database Backup and Disaster Planning 2. Oracle Database Backup SQL Database Backup: Microsoft SQL database backups are most advantageous backup systems. These backups are very easy to run and take less time when compared to other backup systems. There are two kinds of backups in SQL database backups, they are: 1. Database backup under simple recovery model 2. Database backup under full recovery model. Database Backup under Simple Recovery Model. The database backup under simple recovery gives the simple and easy and quick backup of the system. In this case, the backups are done in a step-by-step process. The database is set to potential work loss after every backup completion and this work loss enhances the system and update to the next backup. This series backup is performed in order to provide the system with good performance and also helps in easy recovery of the system from the disaster. In such backup processes, the system can recover to the old stage when the system is infected with some malware or virus since the system contains multiple backups and it can use anyone of those backups to return to the normal state of functioning. Database Backup under Full Recovery Model. The database backup which uses only single step backup process for the whole database is known as database backup under full recovery model. This backup process is time taking process as it creates the images files for whole database at once and keeps that files for recovery of the system. In this case, the backup process may be failed when the system is affected with malware or virus and hence the system cannot recover to the previous stage as it uses only one step backup and if that backup files are 4 Database Backup and Disaster Planning also infected due to the virus, then the whole system must be formatted to get back the system to good condition. But it gives most advantages to the organizations which use this backup process. While the backup is performed, the time and date of the backup is recorded and the transactions logs till that moment are recorded in the backup files. Hence, this gives the user to choose to which stage recovery the user requires and to which transaction details the user is required to go to and recovers the database to that situation to decrease the subsequent changes occurred to the database due to some virus or malware infections. Now-a-days, this backup system is mostly used in laptops and computers in order to avoid the backups to occupy more space in the hard disk. Oracle Database Backup: The oracle database backup system is generally used in business organizations for better functioning of the database backup and recovery options. The database used in business organizations is very large in memory and hence they use oracle backup system. This uses critical backup and recovery processes that are processed within minutes of time. This backup is flexible and simple backup system and helps in data security and availability. Many versions of the oracle database backups such as oracle database 11g release 2, Oracle Solaris 11, Oracle Linux 6.x, Oracle VM 3.0, etc. are introduced into the market along with the increasing demand for the backup systems and with updated versions of the backup. This backup also enhances us to increase the data security and control the data storage in the business environment. Disaster Planning The disaster planning is the precaution measure to save an organization from sudden and unexpected disasters and also helps in organizational early recovery than before. This contains 5 Database Backup and Disaster Planning clear definition of the disasters that occur in an organization and also step-by-step procedure for recovery of the organization. The attributes like integrity of data, information identifying with the safeguarding of its significance and culmination, the consistency of its representation(s) and its correspondence. Data that should be shielded from unapproved, unforeseen, or accidental alteration or annihilation emerged from the data innovation establishment, and the incorrectness bargains the estimation of the data framework. Disaster notice is a notification used to inform clients, representatives and business accomplices with respect to the work administration keeping up around in the association whether it is business association or company. The accompanying graph is the case of warning rundown in company. It gives information about threats for the company and the characterization of threat is, Assets: Identify all organization resources which is substantial and immaterial Exposure: Locate resources and distinguish exposures Losses: Loss of powerlessness information and resources Terrorist's bombings anticipated that would increment Workplace roughness Earthquake. Earthquake tremor demonstrated they can happen anyplace and most don't have a clue about that to do. Your threat can be evaluated by considering your risk, introduction and powerlessness. To see the level of risks in your general vicinity, look at this earthquake tremor perils map. Tornado. It is vital to know where to cover up in the occasion a tornado is coming, particularly for organizations situated in an elevated structure. Gets ready likewise has a tabletop tornado drill to rehearse with your representatives 6 Database Backup and Disaster Planning Hacking. It is extremely convoluted risk for business with a specific end goal to control secure establishment and characterized investigation is to be done to overcome structure the spam or threat. The disaster recovery plan affiliations are obliged to adequately ease the threat rising up out of usage of information and information systems in the execution of mission/business frames. The test for affiliations is in realizing the right plan of security controls. Security controls are picked and completed. Backup phase and recovery phase. The three factors play vital role in data backup are availability, confidentiality, integrity, used for recovering the data, which is lost, of an organization. The associations must make, execute and test powerful plans to manage episodes and calamities. Should recognize physical or procedural perils. Alerting the whole association Protect the wellbeing and security of workers Minimize harm to the association Financial premise for techniques Provides comprehension of the measure of threat to accept Emergency Phase. In this phase, the establishment of occasion operations, post recovery of data innovation works, etc is referred. Moreover, the manager, chief staff of the organization and senior team lead will be under the emergency phase. Emergency - A sudden, startling occasion requiring quick activity because of potential risk to wellbeing and security, the earth, or property. Emergency Preparedness - The order which guarantees an association, or group's preparation to react to an emergency in a planned, auspicious and viable way 7 Database Backup and Disaster Planning Emergency Procedures - An arrangement of activity to start instantly to keep the death toll and minimize harm and property harm. Integration with Database Backup and Disaster Planning The integration is very essential part in the database backup and disaster planning system. These two systems are very closely related to each other. The database backup is created to help the database in recovery process when some unexpected things happen and effect the whole organization to a great extent. The disaster planning is the pre-planned documentation which also contains the information of the backups and recoveries and according to this all the backups and recovery process are performed. When these two techniques are not integrated properly, the system may crash or stop working in the middle of the process and hence leads to damage of the whole system and gives a great loss to the organization. Since, every organization is dependent on the backup and recovery processes, the space and other requirements are to be provided to the system for easy and error free processing of the both techniques. If these processes are not properly done, there may be many losses to the users like data loss, system loss, money loss and many more losses. The integration should be done to the systems by providing even extra hard disks if the system doesn't allow space for the backups. Hence, this makes the efficiency of the system increased and the system works more effectively than before. These processes can't be neglected and should be carefully done in order to increase the system performance. 8 Database Backup and Disaster Planning Reference Database Backup.
