Accounting Information Systems - Chapter 7
Sale Order Event
A mutually commitment event where the enterprise agrees to deliver goods to a customer and the customer pays for goods symbolized by sale order document or date entry screen (e.g. order data, promised delivery date, payment terms, dollar amount, which sales representative and customer participated, what products were ordered, etc.) data to record it is entered into sale order, reservation, and sales call-sale order fulfillment table (if separate table)
What notation is used in a conceptual model to represent a duplicate copy of a class that is already used elsewhere in the model?
A diagonal slash is placed through the bottom right corner of the class's rectangle and the attributes are removed from the class
Economic Increment Events in the revenue cycle
Almost always a cash receipt event External agent transfers ownership of cash (or equivalent) to the enterprise Symbolized by a remittance advice document or data entry screen (e.g. date, dollar amount, customer who cash was received, employee who processed receipt, sale or other revenue generating activity to which cash receipt applied, etc.) Resource- cash Internal Agent- cashiers, accounts receivable clerks or other financing personnel External Agent- customers or clients Date to record cash receipt is entered into cash receipt and duality tables
Sale Event
An economic decrement event in which title (ownership) of one or more products is transferred from the enterprise to a customer. Transfer may take place in person or in transit symbolized by a bill of sale, sale invoice, or similar document or data screen (e.g. date, dollar amount, product which title transferred, payment terms, which sales representative and customer participated) sales that occur via transit are usually also symbolized by a packing list and a bill of lading data to record a sale is entered into the sale and stock flow tables and into the sale order- sale fulfillment table (if separate table)
Customer Inquiry Event
An instigation event that is externally initiated; typically involves a customer contacting the enterprise to inquire as to pricing or availability of products or services data is not typically captured for this event
Sales Call Event
An instigation event that is internally initiated; typically involves a sales representative calling on a customer to describe features of goods or services symbolized by a sales call report document or data entry screen (e.g. which sales representative and customer participated, date, start time, end time, location, what products and/or services were presented to the customer and their reactions, etc.) data to record it is entered into the sales call and proposition tables
Agent-Agent Relationships
Assignment and Responsibility
View Integration
Combing the models together to form a complete whole Involves 3 steps
Resource-Agent Relationships
Custody links resource to internal agent use when an internal agent's responsibility for a resource needs to be tracked INDEPENDENTLY of any event
Sales/Collection Process Events
Customer Inquiry Event Sales Call Event Sale Order Event Sale Event Sale Return Event May be internally instigated (marketing events such as sales calls, advertising campaigns, or promotions) May be externally instigated (customer inquiries) Internal Agents- sales/marketing personnel or customer service representatives External Agents- customers there is no need to specifically identify a good or service but rather information about the good or service is sufficient
Attribute Conflicts
Different attributes used to describe the same class is various views Includes all attributes needed for all transaction cycles as attributes for the class in the integrated model Are resolved by performing a set union of the attributes needed for the different cycles
Event-Event Relationships
Fulfillment, reversal, and reciprocal
View Integration - Step 1
Identify the common classes in two conceptual level views -each pair of cycles that is connected in the value chain shares at least one common resource -many cycles have at least one agent in common -cash receipt events and cash disbursement events exit in multiple cycles
Mutual Commitment Events in the Revenue Cycle
Involve enterprise and an external business partner agreeing to exchange resources at a defined future time Don't always happen at a discrete point in time; often involve a series of activities Internal Agents- sales or customer service representatives and/or order entry clerks External Agents- customers Information about type of good or service is sufficient Enterprises would be able to trace mutual commitment events to the instigation events that triggered them
Resource-Resource Relationships
Linkage and Typification
View Integration - Step 2
Merge the common classes, resolving class and attribute conflicts
Mutual Commitment Events involved in the Acquisition/Payment Process
Purchase Order Event Purchase (acquisition) Event Purchase Return Event typically enterprises would like to be able to trace mutual commitment events to the instigation events that triggered them
Event-Resource Relationship
Proposition and Reservation
Economic Decrement Events in the revenue cycle
Represent the revenue generating activities; the giving up one or more resources in order to get some other resource (usually cash) Do not happen at discrete point in time; may involve series of workflow activities Resources vary for different types of businesses (inventory, labor, temporary use of asset) Internal Agents- salespeople, shipping clerks, delivery clerks, service engagement personnel External Agents- customers or clients
View Integration - Step 3
Resolve association conflicts, including name conflicts and structural conflicts -ensure each association has a unique name -ensure multiplicities are appropriate for associations once common classes are merged
Economic Decrement Reversal Events
Reverse economic decrement events e.g. a sale return reverses a sale event
Economic Increment Reversal Events
Reverse economic increment events Giving something back that you hoped would satisfy your needs e.g. a purchase return reverses a purchase event
Purchase Order Event
Supplier agrees to provide goods to the enterprise who agrees to pay a price for those goods symbolized by purchase order document or data entry screen that summarizes information about event (e.g. order date, promised delivery date, payment terms, dollar amount, supplier and purchasing agent participated, who products enterprise ordered, etc.) data to record this is entered into purchase order and reservation tables
Class Name Conflicts
Synonyms and Homonyms
View Modeling
The separate modeling of each transaction cycle
Purchase Return Event
Title (ownership) for goods previously transferred from a supplier to the enterprise are transferred back from the enterprise to the supplier A resource (or resource type) is decreased as a result but this is considered an economic incremental reversal event symbolized by authorized request to return, packing list, and debit memorandum documents or data entry screens that summarize info about the event (e.g. date, what quantities of which products were returned to supplier, dollar amount, etc.) data to record it is entered into purchase return, stock flow association, and reversal association table (of reversal is separate table)
Sale Return Event
Title (ownership) for products that were previously transferred from seller to buyer is transferred back from buyer to seller A resource is increase as a result, but it an economic decrement reversal event Symbolized by sales return authorization, receiving report, and credit memo documents or data entry screen (e.g. data, what quantities of which products were received from customer, dollar amount, customer involved, employee who processed return, etc.) data to record sale return is entered into sale return, reversal association, and stock flow association tables
Purchase (acquisition) Event
Title (ownership) of product is transferred from supplier to enterprise Transfer may take place in person, or via transit Symbolized by a receiving report document or data entry screen that summarizes info about the title transfer (e.g. date, dollar amount, product for which title transferred, payment terms, etc). data to record this is entered into purchase and stock flow tables
View Modeling and View Integration
Used to reduce complexity and to simplify the reality into manageable pieces when designing information systems
Acquisition Cycle Instigation Event
Usually internally instigated; triggered by an identified need Internal agents involved are usually the department supervisor (who identify the need and authorize the expenditure) and purchasing agents (who process the requisitions) there is no need to specifically identify a good or service but rather information about the good or service is sufficient *external instigation is possible and would involve suppliers
Mutual Commitment Event
When commitments by the enterprise and its partners are combined
Economic Decrement Events in the acquisition cycle
almost always a cash disbursement event enterprise transfers ownership of cash (or equivalent) to a supplier symbolized by a check or disbursement voucher document or data entry screen summarizing info about the event (e.g. date, dollar amount, supplier, employee, acquisition or other event to which cash disbursement applied, etc.) resource- typically cash internal agent- cashiers, accounts payable external agent- suppliers or vendors
Commitment Event
an event in which commitments are made by the enterprise or by one of its external business partners for a part of a future economic exchange
Instigation Event
an event that initiates activities in the business process may be internally (e.g. a marketing event) or externally instigated (e.g. call from suppliers salesperson)
Purchase Requisition Event
an instigation event that is entirely internal (e.g. department supervisor communicating need to purchasing department) symbolized by a purchase requisition document or data entry screen that summarizes info about this event (e.g. which department supervisor and purchasing agent participated, date of request, date when goods/services are needed, etc.) data to record is entered into purchase requisition and proposition tables
Typification Relationship
each resource, event, or agent can be related to a resource type, event type, or agent type
Acquisition/Payment Process Event
involve the enterprise and an external business partner agreeing to exchange resources at a defined future time don't always happen at a discrete point in time; often involve a series of activities internal agents- purchasing agents external agents- suppliers there is no need to specifically identify a good or service but rather information about the good or service is sufficient
Reservation Relationship
link commitment events to resources or resource types
Reversal Relationship
link economic events to the events that reverse them
Reciprocal Relationship
link increment and decrement commitment events is the commitment-level equivalent of duality
Proposition Relationship
link instigation events to resources or resource types
Responsibility Relationship
link internal agent to internal agent use when one internal agent is responsible for another, INDEPENDENT of their mutual participation in an event
Fulfillment Relationship
links instigation events to commitment events and links commitment events to economic events
Assignment Relationship
links internal agent to external agent use only when relationship between internal agent and external agent exists INDEPENDENTLY of their mutual participation in an event
Linkage Relationship
links two resources use to identify resource made up of another resource
Homonyms
one class name used to represent two or more different classes
Event-Agent Relationship
relationship between the added events, and internal agents who participate in them
Economic Increment Events in the acquisition cycle
represent receipt of goods or services (usually paid by cash) do not always happen at discrete point in time; involve a series of workflow activities resources vary for different types of businesses (inventory, services, temporary use of asset) internal agents- purchasing agent or receiving clerk external agents- suppliers or vendors
