An information system(IS) is typically considered to be a set of interrelated elements or componentsthat collect(input), manipulate(processes), and disseminate (output) data and information andprovide a feedback mechanism to meet an objective.
Raw facts such as an employee’s name and number of hours worked in a week, inventory part
numbers or sales orders.
A collection of facts organized in such a way that they have additional value beyond the value of the
facts themselves.

There are two types of TPS: Batch processing Real Time processing
7
In the firm collects data from transactions as they occur, placing them in groups or batches. The system then processes the batches periodically.e.g. : Payroll, cheque, billing for electricity, telephone etc.
In data are processed as soon as a transaction occurs..e.g. : ATMs, airline reservation, library system etc.

Computer Aided Design(CAD) Systems : automate the creation and revision of designs, using computers and sophisticated
graphics software. Provide engineers, designers, and factory managers with precise control over
industrial design and manufacturing. 3ds Max(Autodesk ), Blender(Blender Foundation), Inventor(Autodesk ), Solid
Edge(Siemens PLM Software)
Virtual Reality Systems : Have visualization, rendering, & simulation capabilities that go far beyond those of
conventional CAD system. use interactive graphics software to create computer generated simulations that are so
close to reality that users almost believe they are participating in a real worldsituation.
Provide drug designers, architects, engineers, and medical workers with precise,photorealistic simulations of objects.
Investment Workstations : High-end PCs used in financial sector to analyze trading situations instantaneously
and facilitate portfolio management.

Purpose: facilitate the production of goods Inventory systems
Inventory control: and policy (track goods and materials into, out of,and between inventories use UPC and RFID)
Inventory management: use past data to compute stocking levels,reorder levels, and reorder quantities in accordance with inventorypolicy
Just-in-time (JIT) inventory policy: have production inputs (both rawmaterials and work in process) delivered to the production sitewhenever is needed to reduce the inventory to the minimum
Manufacturing planning systems: plan materials, equipment,people, and facilities for manufacturing Bill of material (BOM): a list of every materials that comprise a
product
