TAILIEUCHUNG - PDF Forms and Database Connectivity Solutions

First, replicas need to check if they are receiving a valid sequence of operations from each client. Most checks are simple, such as verifying if a BEGIN is always followed by a COMMIT/ROLLBACK and if the unique identifiers that are sent are valid. There is one additional aspect that could be exploited by a Byzantine client: the client first executes operations in the coordinator and later propagates the complete se- quence of operations (and results) to all replicas. At this moment, the coordinator does not execute the op- erations, as it has already executed them. A Byzantine client could exploit this behavior by sending a sequence of operations during the COMMIT PBFT. | Amgraf Inc. PDF Conference 2005 PDF Forms and Database Connectivity Solutions By Franklin J. Garner III President and CEO Amgraf Inc. September 26 2005 Introduction Every company and organization uses business forms and now most have PC s with access to the Internet. With great software like Amgraf OneForm Designer Plus OFDP and Adobe Acrobat paper forms can be converted to Internet forms I-forms thereby saving significant costs in printing and storage. With additional effort I-forms can be extended into fillable submittable containers for data capture retrieval presentation and processing. The benefits of database-connected I-forms solutions include improvements in productivity transaction accuracy and user satisfaction. So where s the problem Forms layout and design and even the steps to insert fill fields are usually graphic designer tasks. A non-connected PDF form is a self-contained file with everything packaged within the visual image. To make an I-form submittable the originator must go beyond the form image and interact with software for field data extraction data communication with acknowledgement and navigational methods to start and end the form filling session. These functions have traditionally been performed by computer programmers and are worrisome tasks for graphic designers. Adding database connectivity also introduces another layer of complexity onto I-forms. This white paper is intended to clarify the technical issues involved in implementing an I-forms data collection and retrieval system. Basic Internet Forms Functionality Internet forms can be used for many online transaction functions. The starting point is where the image of a form is converted so that it can be displayed on a computer screen and output to a local printer. Most Acrobat Distiller users have mastered this conversion step and many web sites now have links to PDF forms for user access. Upon clicking a link the free Adobe Reader opens within the browser window and a PDF form is .
