1. Management information system Third Year Information Technology Part 17 Cross-Functional Enterprise Systems Tushar B Kute, Sandip Institute of Technology & Research Centre, Nashik tbkute@gmail.com

2. E-commerce vs. e-business

3. Cross-functional enterprise system It is a group of people with different functional expertise working towards a common goal. It may include the people from finance, marketing, operations, human resources. Typically, it includes employees from all levels of an organization. Cross-functional enterprise system often function as self-directed enterprise systems responding to broad, but not specific directives.

4. evolution Task Orientation Functional Orientation Cross-functional system

5. Application frameworks Customer Relationship Management Supply Chain Management Selling Chain Management Enterprise Resource Management Enterprise Application Integration E-procurement Knowledge Management Decision Support Business Intelligence

6. Cross-functional system architecture Supplier Business Partners SCM Employees ERP Partner Relationship Management Knowledge Management EAI CRM SeCM Customer

7. Collaboration system in manufacturing It is designed for one basic purpose, to help unite employees or people that are working on similar task, or it could be the exact task and system helps unite them to complete their task and achieve whatever goal that task sets out to do. E.g. Slovak, Instant Messaging

8. Enterprise collaboration system Communicate Coordinate Collaborate and Cooperation

9. Tools used Electronic mail Voice mail Bulletin board systems Fax Video conferencing tools

10. Collaboration system in manufacturing Structured collaboration system Easier to organize Excellent for hierarchical organizations Increases proficiency Limitations of structured collaboration system Same workflow information Can cause groupthink Encourages lack of creativity

11. Enterprise application integration The use of software and computer systems architectural principles to integrate a set of enterprise computer applications. It is an integration framework composed of collection of technologies and services which form a middleware to enable integration of systems and applications across the enterprise.

12. Transaction processing systems A 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 in an information system. The essence of a transaction program is that it manages data that must be left in a consistent state. E.g. if an electronic payment is made, the amount must be both withdrawn from one account and added to the other; it cannot complete only one of those steps

13. Single-User System centralized system DBMS presentation application services services user module Presentation Services - displays forms, handles flow of information to/from screen Application Services - implements user request, interacts with DBMS ACID properties automatic (isolation is trivial) or not required (this is not really an enterprise)

14. Centralized Multi-User System Dumb terminals connected to mainframe Application and presentation services on mainframe ACID properties required Isolation: DBMS sees an interleaved schedule Atomicity and durability: system supports a major enterprise Transaction abstraction, implemented by DBMS, provides ACID properties

15. Centralized Multi-User System communication central machine presentation application services services • • • DBMS presentation application services services user module dumb terminal

16. Transaction Processing in a Distributed System Decreased cost of hardware and communication make it possible to distribute components of transaction processing system Dumb terminal replaced by computers Client/server organization generally used

17. Two-Tiered Model of TPS database server machine client machines presentation application services services • • • DBMS presentation application services services communication

18. Three-Tiered Model of TPS database server machine application server machine client machines presentation server DBMS • • • application server presentation server communication

19. features Rapid response Reliability Inflexibility Controlled processing

20. types Batch processing Real time processing
