For process bubble "Issue and record disbursements", identify each information input and output into or out of the process (make sure to say whether each item you identify is an input or an output) 2. For the same process bubble, use another data flow diagram from the text to identify where the GL cash disbursements update is sent 3 What level of DFD is represented in Figure 13.67 Question 6 (3pts)

Answer 1

1.A data-flow diagram (DFD) is a way of representing a flow of a data of a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself.In DFD, following are the five primary steps in the cash disbursements process at DFD:

1. Receive vendor invoice and record payable

2. Prepare the check

3. Sign and send the check and cancel the invoice

4. Record the cash disbursement

5. Post the cash disbursements to the accounts payable ledger

In DFD, following are the five primary steps in the cash disbursements process at DFD:

1. Receive vendor invoice and record payable

2. Prepare the check

3. Sign and send the check and cancel the invoice

4. Record the cash disbursement

5. Post the cash disbursements to the accounts payable ledger

Each of these processes is represented by a circle or bubble in Figure below. Since this is the Starting level of DFD, have to assign each of these processes a real number, with the first digit after the decimal point being a zero. One has to also place the circles in the order that the data should flow in the process' As a result, "Receive and Record Invoice" is assigned process 1.0, "Prepare Check" is assigned process 2.0, 'Approve and Sign Check" is 3.0, "Record Cash Disbursement" is 4.0, and "Post Cash Disbursement to Accounts Payable Ledger" is 5.0. This numbering system allows us to decompose these processes into more detailed sub processes and still keep a consistent numbering system. Thus, if there will be need to decompose process 3.0 to a more detailed level, one could assign sub process bubbles as 3.1,3.2,3.3, etc. One can even provide greater detail by decomposing process 3.1 into sub processes 3.1.1,3.1.2,3. i1.3, etc.

Next, has to place the data sources and data destinations on DFD. Because of having only one data source and destination (i.e., the vendor), have to draw a square and label it “Vendor” lt is very important to reconcile back to the context diagram to prepare the different levels of DFDs. That is, the same data sources and destinations that appeared on the context diagram must also appear on the level of DFDs. No new data sources and destinations may appear on the starting level of DFD. If, when preparing the starting level of DFD, one will discover that a data source/destination, is necessary to document the system properly, then one must revise the context diagram with the new data source/destination, because the context diagram should represent the entire process.

Once the data source/destinations and processes are drawn, then connect them by drawing the arrows between the appropriate symbols. These arrows represent the data moving or flowing from one process to another and from one source or destination to or from a particular process' Accordingly, vendor invoice will be moving from the vendor to the Receive and Record Invoice" process and from that process to the "Prepare Check', process. The vendor invoice and a check move from the "prepare check, process to the. Approve and Sign check, process' Having arrows leaving process 3.0 to represent the signed check being-sent to the vendor and the cancelled invoice going to process 4.0, Record cash Disbursements. Some processes require that data be stored. As a result, one should also draw any necessary files or data stores. The starting level of DFD is the first time data stores appear in a DFD set. (Note: Data stores should not be represented on a context diagram.) Data store labels should identify the data being sent to or from it. As a result, labeling the data flows to or from data stores is normally unnecessary Data stores are prepared by drawing two parallel lines and inserting the name of the data store between the parallel lines. In Figure they are three data stores: the cash disbursements journal, accounts payable subsidiary ledger, and the cancelled invoices data store. Because the cash disbursement Journal is updated in process 4.0, a data flow is sent from the process 4.0 circle to the cash disbursements journal data store.

Vendor Vendor Invoice 1.0 Receive & Record Invoice Vendor Invoice Accounts Payable (AP) Subsidiary Ledger Signed Check Vendor Invoice & Check 2.0 Prepare Check Cash Disbursements (CD) Journal 3.0 Approve & Sign Check Cancelled Invoice 4.0 Record Cash Disbursement Cancelled Invoices 5.0 Post CD to AP Ledger
