The main idea of this final paperwork, entitled “Electronic office business and business processes” is to show the business that takes place in the office business. Office business is a system of technical actions and procedures which ensures efficient organization, search and storage of documents. This paperwork is divided into several chapters from which every one of them makes a separate unit. First chapter refers to electronic business. In the second chapter the fundamental concepts of office business, such as registry office, archives, submission classification code etc. are considered. All of these concepts are crucial for business, because, without them, the operation wouldn’t be functional. The third chapter shows the term and basic features of electronic business. Here we can conclude that the wide use of electronic business refers equally to public and private sector just as it applies to use of information and communication technologies. It’s also important to mention that an electronic signature implies a whole set of data in electronic form, by which the identification of the user is provided as well as the verification of the authenticity of the signed electronic document. The fourth chapter explains business processes. This last part focuses on business information systems which consist of input and output data that are available and usable to anyone who needs it.
