The Central Warehouse staff sends the merchandise to the store, files its copy of the GRF form in its records by date, and updates the inventory record of the company on inventory cards manually. a. Prepare a system flowchart for Goods Requisition Process at Sun Food as described above b. Prepare a dataflow diagram for Goods Requisition Process at Sun Food as described above Document A rectangle with a curved bottom represents a document or report. Examples: Sales Invoice, Customer Order: Receiving Report; Purchase Order; Deposit Slips, pay checks; etc. Manual Operation The trapezoid shape is used to show a process, task, action, or operation that is done manually by hand.

Disk Storage A cylinder represents a data file or database on magnetic disc or hard drive (a direct access storage) Omine Storage The shape represents offline storage, regardless of the storage medium. Use a letter to indicate the filling system as follows: Manual Input D-Storing by date A - Storing alphabetically N-Storing by document Number This shape looks like a side view of a keyboard and is used to represent entering data into a computer via a keyboard. Normally, it appears before a computer operation, representing data entry. On page Connector A If you need to connect to another section of the flowchart, and can't draw a line, you can use a circle. You draw the line to the circle and label the circle with a letter. Then you place a copy of the circle where you want the flowchart to continue. This should be avoided, but sometimes is necessary. This shape means the flowchart continues on another page. A letter or page number in the shape tells you where to go Off Page Connector Time Card It is used to represent time cards. Terminator This shape is used to show where the flowchart ends. Flowcharting Shapes To draw a dataflow dingram, first we should learn the flowcharting shapes discussed in Chapter 3. There are only four symbols used in a dataflow diagram as follows: Data Source and Destination: Squares represent source or destination of data (inflow or outflow). Square is labeled with the name of the data source or destination Process: Circles represent the process that take data inflows and transform them to information outflows. Circle is labeled with the process name. Data Stores: Two parallel straight lines display a store or collection of data. A description of the data store content is entered on the symbol
