Friends, Deb Armstrong and I have reached the culmination of our editorial term, and K.D. Joshi of University of Nevada-Reno has been chosen as the new Editor-in-Chief. Professor Joshi is a long-time contributor, Senior Editor, and thought leader in our parent organization, ACM SIGMIS, and its venerable CPR conference. K.D. has a marvelous vision, superb connections with our ACM SIGMIS CPR constituency, and an operational record second to none. She will be a great leader for continuing the growth trajectory of The DATA BASE for Advances in Information Systems.

<p class="p1">Keys consisting of variable-length chamcter strings from the front and rear of surnames, derived by analysis of author names in a particular data base, am used to provide approximate representations of author names. When combined in appropriate ratios, and used together with keys for each of the first two initials of personal names, they provide a high degree of discrimination in search.</p> <p class="p1">Methods for optimization of key-sets are described, and the performance of key-sets varying in size between <span class="s1">150 </span>and <span class="s1">300 </span>is determined at file sizes of up to <span class="s1">50,000 </span>name entries. The effects of varying the proportions of the queries present in the file are also examined. The results obtained with fixed-length keys are compared with those for variable-length keys, showing the latter to be greatly superior.</p> <p class="p1">Implications of the work for a variety of types of information systems are discussed.</p>

Everyone involved in geospatial information systems has heard of Environmental Systems Research Institute (Esri)company. Most people have tried ArcGIS software at least for one time. Esri has been the pioneer in this industry for a long time; it also defines the future of geospatial trends. In this chapter, the author adopts a neutral position to discuss the relation of Esri and open-source community. They cover almost every aspect where Esri and open source co-occur. Even the latest achievement of Esri, which is R-bridge, is discussed here. Going into the details of everything is not the goal of the chapter; however, a minimum description is provided for each section. Proper references are given to the reader for further study.

The paper discusses the photogrammetric methods and process of creating geodata for aeronautical information databases. Efficient technology for collecting data on terrain, obstacles and cartographic information using satellite and aerial photos is given. The measurement, selection and evaluation of spatial data have met the international requirements for the completeness and accuracy as well as the developed structure of the attribute data base. The advantages of digital photogrammetric system and geographic information systems as the main software for aeronautical data gathering, are considered.

To support the vision of UIN Suska Riau, so established the Technical Implementation Unit field of computer and information systems UIN Suska Riau called Computer Center (PUSKOM). However, in 2013, Computer Center (PUSKOM) UIN Suska Riau renamed the Center of Information Technology and Database (PTIPD). Center for Information Technology and Data Base (PTIPD) UIN Suska Riau is a part that manages the use of information technology in environment UIN Suska Riau. PTIPD provide internet network with current bandwidth capacity of 200 Mbps. PTIPD also conduct training in information technology for students and faculty and to develop information systems and applications as needed academic community UIN Suska Riau. Development of information systems that are not systematically planned will lead the organization does not have the priority scale development projects / IT and impressed patchy. This way will impact on the productivity of the organization. Center for Information Technology and Database (PTIPD) requires strategic planning of IS / IT should be appropriate, because if the IS / IT is not appropriate either target or goal, then the IS / IT will not be a competitive advantage for the Center for Information Technology and Database (PTIPD ) UIN Suska Riau. Form of Strategic Planning Information System that discussed in this study is to use a methodology Ward and Peppard, with the input of the internal business environment analysis and environmental analysis of the internal IS / IT. The results of this analysis define the design strategy plan IS / IT for the Center for Information Technology and Data Base (PTIPD) UIN Suska Riau. Keywords : PTIPD, Strategic IS / IT, Strategic Planning SI / IT, Ward and Peppard
