(20 cards)
letters & numbers are interspersed to identify an item. The mnemonic code is derived from the description of the item & is usually easy to memorise
Mnemonic codes
- be consistent with its intended use, which requires that a code designer determine desired system outputs prior to selecting the code - allow for growth - be as simple as possible to minimise costs, facilitate memorisation & interpretation, & ensure employee acceptance - be consistent with a company’s organisational structure & across a company’s divisions
Guidelines that result in a better coding system?
a list of numbers assigned to each general ledger account. - a great example of coding
Chart of accounts
used to record infrequent or non-routine transactions, such as loan patents & end-of-period adjusting & closing entries
General journal
records large numbers of repetitive transactions such as sales, cash receipts & cash payments
Specialised journal
a traceable path of a transaction through a data processing system from point of origin to final output, or backwards from final output to point of origin.
Audit trail
something about which data is stored, such as employees, inventory items & customers
Entity
each entity has attributes or characteristics of interest, that are stored, such as pay rate & address. Each type of entity possess the same set of attributes.
Attributes
computers store data in a field
Field
Specification for values of data elements comprising a database , prescribed to ensure data consistency. Is a field within a record.
Data value
a group of related records
File
like a ledger in a manual AIS, stores cumulative data about an organisation. Inventory & equipment master files store data about important organisational resources. Customer, supplier & employee master files store data about important agents with whom an organisation interacts. Permanent; they exist across fiscal or accounting periods. Individual master file records may change frequently
Master file
contains records of individual business transactions that occur during a specific time. Not permanent & may not be needed beyond the fiscal period. They are usually maintained for a specified period for backup purposes, as well as for audit & tax investigations.
Transaction file
a set of interrelated, centrally coordinated files
Database
CRUD: Creating Reading Updating Deleting
Four different types of data processing activities?
1) Creating new data records 2) Reading, retrieving or viewing existing data 3) Updating previously stored data 4) Deleting data
CRUD?
updating done periodically, such as daily
Batch processing
most companies update each transaction as it occurs. It ensures that stored data in master files are always current, thereby increasing it’s decision-making usefulness. It is also more accurate because data input errors can be corrected in real time or refused.
Online processing / realtime processing
- document - report - query response
Information is usually presented in one of the three forms?
records of transaction or other company data
Documents
