Computerized batch processing is a method of running software programs called jobs in batches automatically. While users are required to submit the jobs, no other interaction by the user is required to process the batch. Batches may automatically be run at scheduled times as well as being run contingent on the availability of computer resources.
A simple example of a job stream is a system to print payroll checks which might consist of the following steps, performed on a batch of inputs: Read a file of data containing employee id numbers and hours worked for the current pay period (batch of input data).
If the accountant is using a general ledger accounting system, which lacks true job costing functionality, the costs must be manually transferred out of Work in Process to Finished Goods (Cost of Goods Sold for service industries). Of course, in the days of computerized job costing software, journaling costs manually is an obsolete process.
The disadvantages of planning a small batch are that there will be costs of frequent ordering, and a high risk of interruption of production because of a small product inventory. [12] Somewhere between the large and small batch quantity is the optimal batch quantity, i.e. the quantity in which the cost per product unit is the lowest. [12]
The most recent backup is the son, the previous the father, and the oldest backup is the grandfather. This method is commonly used for a batch transaction processing system with a magnetic tape drive. If the system fails during a batch run, the master file is recreated by restoring the son backup and then restarting the batch.
An OLTP system is an accessible data processing system in today's enterprises. Some examples of OLTP systems include order entry, retail sales, and financial transaction systems. [5] Online transaction processing systems increasingly require support for transactions that span a network and may include more than one company.
BatchPipes Version 1 was developed in the late 1980s and early 1990s simply as a technique to speed up MVS/ESA batch processing. In 1997 the functionality of BatchPipes was integrated into a larger IBM product - SmartBatch (which incorporated two BMC Corporation product features: DataAccelerator and BatchAccelerator).
Process costing is an accounting methodology that traces and accumulates direct costs, and allocates indirect costs of a manufacturing process. [1] Costs are assigned to products, usually in a large batch, which might include an entire month's production. Eventually, costs have to be allocated to individual units of product.
