Data - -Facts collected, recorded, and stored in a system (e.g., numbers, dates, names) that
alone have no meaning without context.
--Information - -Data that has been organized and given context to make it meaningful and
useful for decision making.
--Information overload - -A condition where too much information reduces the quality of
decision making.
--Information Technology (IT) - -Technology used to help decision makers more effectively
filter and condense information.
--Value of information - -Information is valuable when the benefits of having it exceed the
costs of gathering, maintaining, and storing it.
--Accurate (information characteristic) - -Information that is correct and free of error.
--Complete (information characteristic) - -Information that does not omit important aspects
of events or activities.
--Relevant (information characteristic) - -Information that reduces uncertainty and improves
decision making.
--Timely (information characteristic) - -Information provided in time for a decision maker to
act on it.
--Verifiable (information characteristic) - -Information that two independent people can
produce the same result from the same data.
--Machine-readable format - -A data format that can be read and processed by a computer;
XBRL is an example.
--Business process - -A set of related, coordinated, and structured activities performed by
people or machines to achieve a specific organizational goal.
--Transaction - -An agreement between two entities to exchange goods, services, or any

--Financing cycle - -The business process: give cash — get cash (borrowing and repaying).
--Accounting Information System (AIS) - -A system that collects, records, stores, and
processes data to produce information for decision makers; includes people, processes,
technology, and controls.
--How does an AIS add value? - -By improving product/service quality, improving efficiency,
sharing knowledge, improving supply chain, strengthening internal controls, and improving
decision making.
--Artificial Intelligence (AI) - -The use of computer systems to simulate human intelligence
processes such as learning, reasoning, and self-improvement.
--Data analytics - -The use of software and algorithms to find and solve problems and
improve business performance.
--Cloud computing - -The use of a browser to remotely access software, data storage,
hardware, and applications.
--Virtualization - -Running multiple systems simultaneously on one physical computer.
--Internet of Things (IoT) - -The embedding of sensors in devices so they can connect to the
Internet.
--Value chain - -Links together the different activities within an organization that provide
value to the customer; includes primary and support activities.
--Primary activities (value chain) - -Value chain activities that provide direct value to the
customer.
--Support activities (value chain) - -Value chain activities that enable primary activities to be
efficient and effective.
--Supply chain - -An extended system including the organization's value chain as well as its
suppliers, distributors, and customers.
--Data processing cycle - -The four steps used to process transactions: data input, data
storage, data processing, and information output.
, --Source documents - -Records that capture data at the source when a transaction takes
place (paper, turnaround, or automated).
--Turnaround document - -A document sent to an external party and returned to the
company to be used as input (e.g., a utility bill stub).
--Source data automation - -Capturing transaction data directly from machines at the point
of origin (e.g., POS scanners).
--Chart of accounts - -A numbered list of all accounts used by a company to record
transactions.
--Sequence code - -Items numbered consecutively to account for all items (e.g.,
prenumbered forms).
--Block code - -Blocks of numbers reserved for specific categories of data (e.g., all products
starting with 2 are refrigerators).
--Group code - -Two or more subgroups of digits used to code an item (e.g., a car VIN
number).
--Mnemonic code - -Letters and numbers interspersed to identify an item (e.g., DRY300W05
for a dryer).
--General ledger - -A complete record of all financial transactions organized by account.
--Subsidiary ledger - -A detailed ledger that supports a control account in the general ledger
(e.g., accounts receivable by customer).
--Audit trail - -A path that allows a transaction to be traced from its source document
through journals and ledgers.
--Master file - -A permanent file of records that is updated periodically (e.g., customer
master file).
--Transaction file - -A temporary file containing recent transactions used to update a master
file.
--Batch processing - -Accumulating transactions and processing them all at once at a
scheduled time.
--Online, real-time processing - -Processing transactions immediately as they occur.
--Enterprise Resource Planning (ERP) system - -An integrated system that connects all
business processes (revenue, expenditure, production, payroll, G/L) across the entire
organization.
