The most important concept which i learnt in this course are the overall system design .We learnt how to use information technology is use as a combination of hardware and software products and services that companies use to manage,access,communication and share information.the main components of the information system are hardware ,software,data,processes and people .how system development life cycle works with planning ,analysis ,design and implementationvarious system development methodologies and how RAD and JAD works with agile methods,how companies use EDI,common reason for system projects , advantages of system review committee,the tangible and intangible benefits and different fact finding techniques that system analysts use during th preliminary investigationDifferent system requirements and how traditional methods of fact finding ,how JAD is different from RAD . The project team works with teamspirit. what type of feaseability issues analysis with oraganizations.Information about project management like create gantt chart,PERT chart,what requirement determination are used for analysis phase.how to make context diagram and 0 diagram, the symbols which are used in DFD’s,how to balance DFD’s data flow diagrams,context level diagram and ERD diagram,how to develop entities and make attributes ,different types of relationships,cardinality and how to build relationship diagrams and to convert tables into different normal forms .most common reason for choosing company the in house approach,information about request of perposal and request of quotation.swe learnt different design strategies and moving from physical to logical models.Architecture design includes architectural components,server based architectures and client based architectures and client server architectures and client server tiers,what are the requirements for creating an architecture designlike operational,performance,security and cultural and political requirements.Different specification of software and hardware and what concept do we use for applying at CD selection. How ERP can extend to suppliers and customer in a process in supply chain management,discssion about middle ware as a software that connects dissimilar application and enables them to communicate and exchange data.The impact of the internet on system architecture,how online processing and batch processing performed.Difference between various topologies and hoe they work on their platforms and where does system implementation fit in the SDLC,what design are used for implementation,got information about structure charts,symbols and cohesion and coupling.how unit testing ,integration testing and system testing is performed in system analysis and design.What type of documentation does the analyst prepare and which system change over methods are used .We got knowlegde about system operation ,support and security,classification of maintenance about release methodology and the advantages of release methodology in system operation, the purpose of capacity planning and steps in requesting maintanance. different levels of security and different types of obsolescence that approach the information system. i have some problems in cardinality and relationship,they are little bit difficult and i will try again and again to understand the concept of many to many and many to one ,one to one because these are the main in the ERD diagram.
