Question

The business environment is increasingly demanding the use of On Line Real Time (OLRT) systems for more up-to-date information. Discuss in detail the issues related to the adoption (or not as the case may be) of an OLRT system. Your answer should include (but not be limited to) implementation and operational concerns, matters related to the qualities of information, internal controls issues, the advantages and disadvantages of OLRT etc.. To illustrate your answer, identify a specific situation in which periodic/batch processing is sufficient to support the business process, and a second situation where immediate processing is necessary to adequately support the process.

Answer 1

On Line Real Time (OLRT) Systems

Online ongoing (OLRT) frameworks assemble business occasion information at the hour of event, update the ace information quickly, and give the outcomes emerging from the business occasion inside a brief span. i.e., progressively. OLRT frameworks complete all phases of business occasion information preparing in quick mode. Prompt mode is the information preparing mode in which there is almost no postponement between any two information handling ventures (rather than occasional mode, in which there is a critical deferral between at least two information preparing steps).

OLRT frameworks normally require three essential sub-procedures to be finished before an occasion is changed over into data that can be utilized by leaders. Figure shows every one of these sub-forms.

Business occasion event and recording of occasion information: At the hour of the business occasion, related information are entered straightforwardly into the framework. Source archives are rarely utilized, as they essentially moderate the procedure and expel a portion of the benefits of non repetitive information section. Notice that the information passage process where the deal is gone into the framework is equivalent to in Figure. This procedure is predictable with the utilization of online exchange section (OLTE) for OLRT frameworks.

Update ace information: Each business occasion went into the framework is handled exclusively and any counts and synopsis finished. This data is then used to refresh the ace information. Note in Figure that the handling is presently being done nearby where the business occasion information are entered. Since every business occasion is handled freely and promptly, the ace information at some random time will be close to being forward-thinking.

Create reports and bolster inquiries: It is neither functional nor alluring that reports be produced after every business occasion is recorded and ace information have been refreshed. Regularly, material reports are produced by the framework on an intermittent premise. Simultaneously, notwithstanding, these reports are typically quickly accessible through access to the framework on an as-required premise, as showed in Figure with the interchanges connects to the deals and stock chiefs. One of the principle points of interest gave by numerous OLRT frameworks is a capacity to check the present status of ace information things at some random time.

Advantages:

• ​​​​​​​Allow reports and queries to be executed at any time from up-to-date data.
• Data entered directly to information system  at the time and place the transaction occurs.Transactions are processed individually and master files are updated instantaneously.
• It allow users to nearly eliminate the delay in accessing up-to-date information.

Disadvantages:

• Requires expensive software, hardware and communication system.
• Transactions can not be integrated on a local computer to be transferred later to a data processing center.
