Until the 1990s, before the widespread adoption of personal computers and the Internet, companies were using information systems to manage data processing and record-keeping activities associated with business transactions like maintaining the general ledger (book keeping), payroll, billing, inventory management, etc. The focus was mainly on maintaining files and databases related to day-to-day operations. Communications, both internal and external, relied on paper, telephone, faxes, and other analog media. Today, companies have eliminated the inaccuracy of paper-based tracking by implementing ERP systems. 63 percent of companies used their ERP software to eliminate inefficiencies in processes such as order tracking.

Drawbacks of offline information system

Many reasons you have to eliminate the offline information system like:-

1. Access Time

One of the primary disadvantages of traditional file systems is the time it takes to access data. It can take minutes if not hours to locate a few files in a large paper filing system. Electronic databases allow for almost instantaneous access to information. Faster data access time can increase the productivity of managers, analysts, accountants and other workers who use data on a regular basis.

2. Editing and Communication

Traditional file systems are cumbersome in that they do not allow users to easily edit files or send information to others. Paper files often cannot be edited directly, forcing users to make new copies to update old files. To distribute data on paper files, users must mail, fax or scan the data. Databases allow users to edit information fields directly, and because information is stored digitally, it is already in a form that can be easily transmitted.

3.Order of data

Data can get out of order in traditional filing systems. If someone accidentally puts a file in the wrong place, or takes a file out of a cabinet and forgets to put it back, it can lead to lost data or the creation of additional copies of files. Electronic filing systems allow users to quickly check whether information already exists somewhere in the system, which helps avoid problems like redundant files and data loss.
