Example of Assist in developing business strategies
Long-term Business decisions, Executive Information Systems (EIS) On line executive information systems would likely provide strategic level information to company leadership, not analytical data to managers.
Functions Performed on Data
Collect, Process, Store, Transform, Distribute
What's the sequence of events under an AIS
Transaction data from paper source documents is entered into the AIS by an end user;
The original paper source documents, if exist, are filed;
The transactions are recorded int he appropriate journal;
The transactions are posted to the general and subsidiary ledgers;
Trial Balances are prepared;
Financial Reports are generated.
Avon Corporation has a management information system. From the management information system, several different reports are available, including reports that are monthly budget vs. actual reports, reports that highlight where sales representatives have not met their assigned sales quotas, account analysis reports that can be requested by accountants as needed as a part of the closing process, and reports that are created by end users to obtain information as needed at any time during the month. The 4 types of reports are best described as:
Demand reports, scheduled reports, exception reports, and ad hoc reports.
Scheduled reports, exception reports, demand reports, and ad hoc reports.
Scheduled reports, ad hoc reports, exception reports, and demand reports.
Exception reports, scheduled reports, demand reports, and ad hoc reports.
In batch processing, the grandfather-father-son file rotation procedure can be used either to recover from processing problems or to retain files off-site for disaster recovery.
Batch totals, often used in batch processing, are totals of dollar fields in transactions. The total computed from the batch is compared to an input batch total for the batch of transactions; if the two totals are the same, processing of the batch can continue.
Hash totals, often used in batch processing, are totals of fields in transactions other than dollars. The total computed from the batch is compared to an input hash total for the batch of transactions; if the two totals are the same, processing of the batch can continue.
In the past, batch processing predominated. These days, there is no justification for batch processing.
I, II, and III are correct.
Mill Co. uses a batch processing method to process its sales transactions. Data on Mill's sales transaction tape are electronically sorted by customer number and are subjected to programmed edit checks in preparing its invoices, sales journals, and updated customer account balances. One of the direct outputs of the creation of this tape most likely would be a:
Report showing exceptions and control totals.
In a batch processing system, one of the input controls would be a report showing exceptions and a control total for all invoices processed in each batch.
Which of the following are components of a Business Information System (BIS)?
Hardware, software, network, people, and data.
The term Data Processing (DP) has come to have the same meaning as which processing methodology?
Electronic Data Processing (EDP) is the use of IT to perform an organization's transaction oriented data processing. EDP is a fundamental AIS application in every organization. As computer technology has become commonplace, the term Data Processing (DP) has come to have the same meaning as EDP.
During the annual audit, it was learned from an interview with the controller that the accounting system was programmed to use a batch processing method and a detailed posting type. This would mean that individual transactions were:
With batch processing, input documents/transactions are collected and grouped by type of transaction. These groups (called batches) are processed periodically (e.g., daily, weekly, monthly, etc.).
Production and test data are normally stored together in the same databases.
Production and test data are normally stored separately, with the production data stored in production databases and the test data stored in test databases.
Access to production and test data are normally the same.
The general characteristic of transactions processed within individual transaction cycles is that:
Transaction cycles generally capture few generic transactions (e.g., customer orders) and process them repeatedly in a nearly identical fashion. Transaction cycles are established to organize and process data in an efficient manner.
Security Federated Insurance Company numbers its insurance policies with a 10 character code that identifies the type of property or casualty insurance sold, the policy year, the customer type, and a customer number. Numbering of this character is an example of:
Group coding embeds intelligence into the identification numbers associated with a particular item. The identification of different features of an insurance policy with specific numbering scheme is an example of group coding.
not block coding..
what type of coding represents assignment of blocks of numbers to broad categories of items (e.g., a general ledger chart of accounts that assigns assets to the 1,000 series of account numbers, liabilities to the 2,000 series, etc.).
What type of coding purely numbers documents, transactions, or other items in order.
What is the subject of the stored information (employee, customer)
What is the data of specific interest for each entity (rate of pay for employees, credit rating for customers)
Data values are stored in a physical space known as _____.
This might be the employees name or the customers street address.
The attributes gathered about an entity are accumulated in fields that comprise a ____
(employees, name, address, W-4 status, rate of pay)
The content of fields are typically referred to as ___
Records are grouped into ____
Similar to a ledger, the _____ stores cumulative information
Similar to a journal, the ____ stores individual transactions
Files that are interrelated and coordinated are referred to as a ______
Concepts of computer storage define a logical sequence of smaller to larger components of stored data that would most likely be displayed as follows:
Fields comprise records that are organized into files that create databases.
Which of the following terms best describes a payroll system?
transaction processing system (TPS) On line transaction processing systems would process customer payments or other transactions, not analyze or trend transactions.
An employee mistakenly enters April 31 in the date field. Which of the following programmed edit checks offers the best solution for detecting this error?
The only programmed edit checks in the choices are reasonableness checks and edits for mathematically accuracy. Obviously, April does not have 31 days. A check on this kind of data entry would be easy to implement and is standard.
The process of capturing data and ultimately producing information output is referred to as:
Transaction processing contemplates data capture through information output.
Credit Card International developed a management reporting software package that enables members to interactively query a data warehouse and drill down into transaction and trend information via various network set-ups. What type of management reporting system has Credit Card International developed?
Online analytical processing allows end users to retrieve data from a system and perform analysis using statistical and graphical tools. A credit card company's system that enables members to interactively query a data warehouse and drill down into transaction and trend information is an online analytical processing system.
input documents/transactions are collected and grouped by type of transaction. These groups are processed periodically (daily, weekly, monthly). Either use sequential storage devices or random access storage devices
What type of processing always has a delay
what are the steps in batch processing
1 create a transaction file
2 update the master file
This type of processing, the master files are updated as the transactions are entered. It requires random access storage devices. It is immediate processing. (POS systems, scanners)
online real time processing (OLRT)
this type of environment maintains all data and perform all data processing at a central location. Mainframe and large server computing applications
occurs when computing power, applications, and work are spread out (or distributed) over many locations
decentralized (distributed) processing (may result in inconsistent processing at a various processing locations)
this type of report is available on demand. the end user can log onto a workstation and obtain a response in the form of a report without waiting for the scheduled time.
reports are produced when a specific condition or exception occurs
report that does not currently exist but can be created on demand, without having to get a software developer.
ad hoc reports
information can be pushed and sent toa computer screen or computer desktop.
used by organizations to present summary information necessary for management action
