Difference between e-resuming system of bdjobs and phrotom alo.com
A manual system analysis require individuals to supply input directly into a system designed to simulate real life events. An automated system is controlled by technology to automatically supply input.
Systems approach involves a combination of three approaches: the classical approach, the behavioral approach and the management science approach. Contingency approach on the other hand combines two or more of the other approaches depending on the given situation.

System analysis and design (SA&D) and object-oriented analysis and design (OOAD) are two different approaches to the development of computer-based information systems. SA&D is a traditional approach that focuses on understanding the requirements of the system, analyzing the current system, and designing a new system that meets those requirements. It is a process-oriented approach that typically involves creating a detailed specification of the system before beginning development. On the other hand, OOAD is a modern approach that focuses on modeling the system as a collection of objects that interact with each other to achieve the desired functionality. It is a more object-oriented approach that involves designing a system by first identifying the objects in the system, their properties, and the relationships between them. Some of the key differences between SA&D and OOAD are: Focus: SA&D focuses on the process of designing a system, while OOAD focuses on the objects in the system and their interactions. Design: SA&D is typically a top-down design approach, while OOAD is a bottom-up design approach. Requirements gathering: SA&D emphasizes the gathering of requirements and creating detailed specifications before beginning development, while OOAD emphasizes rapid prototyping and iterative development. Abstraction: OOAD relies heavily on abstraction, while SA&D relies more on specific details and processes. Overall, both SA&D and OOAD are valid approaches to the development of computer-based information systems, and the choice between them depends on the specific needs and requirements of the project.
system analyst is a person who investigates the system and identifies the components that are required to realize the system.and identifies those roles. where as designer specifies how to solve the problem specified in requirement analysis.
behavioural approach is a field of information system that deals with behaviour issues arising from the developed system and long time maintenance of the information system also deals with issues that cannot be explode using formulas.technical approach this approach emphasis on three things- mathematical based models to study an information system-looks at physical technology and formal capability of the system- emphasis at identifying solutions that can be represented by formulas
Systems are created to solve problems. One can think of the systems approach as an organized way of dealing with a problem. In this dynamic world, The subject System Analysis and Design, mainly deals with the software development activities.

The difference is a point of analysis, whether the origin or center point or zero point in analysis is at the earth or at the sun. This does not force a theory about the center of the Universe. You could describe the United States from the center in Washington, or a center in Chicago. the distance between Chicago and new York would be the same. The center point of analysis is relative and a point of convenience. Astronomers and Astrologers use the geocentric system for convenience. The Middle Ages debate about the Earth being the center of universe was about religion not science or analysis. The heliocentric view offered a more convenient analysis of the solar system than the geocentric system, but for events on earth, the geocentric system is better for analysis still and is used today, Right Ascension system.
