Use of databases

Before making a search it is very important to check the concepts which may be searched. The operating program provides an opportunity to check the index, to see if the concept you are looking for is featured in the database itself, and how many times. By clicking on the INDEX button, you go to the beginning of the given index. When you write in the START field, the program jumps to the word which is entered (or if it does not exist, then to the closest to it).
When searching, it is also possible to enter a PATTERN. This is worthwhile using when you are searching in an index of expressions, and you do not know if the word you are searching for is at the beginning of the expression. Then it is particularly useful to use CHARACTER REPLACEMENT SYMBOLS:
*: replaces an arbitrary number of characters
!: replaces exactly 1 character
?: replaces 0 or 1 characters
Words (or possibly expressions) are seen on the index hit list, with the number of items in front.

Display of pictorial elements
Rapid and efficient display of large-sized pictures is achieved with the help of the AAGISVIEW client program, which is to be downloaded before use. More precisely, if it has not been downloaded, on attempting to display a picture a warning is given to download it. System owner authorisation is required for downloading and installing the program!
The pictures to be displayed may be independent (one record, one picture), or they may be "in series", which means that several pictures belong to a given record, or the pictures form an independent system, and the pictures belonging to the various records may be studied independently.
To display the "in series" pictures, the list of pictures is seen in the lower right corner and this may be opened with the + sign. A miniaturised copy of the picture (which may be adjusted) appears in the upper right corner, and on this can be seen where the picture detail displayed in the main window is to be found.
Besides the "simple" picture display, the program is also suitable for the synchronised display of georeferred maps. For one thing, this means that the coordinates of the given point appear in the lower right corner of the screen (in both the old and the modern GPS coordinate systems). In this case, the list seen in the lower left corner signifies georeferred maps, which may even be displayed in parallel. There are more than 100 georeferred maps in the Budapest topography database, which show the same territory on maps at various resolutions and dating from different times. When you "move" across one map, all the other maps follow the movement, so it is possible to study the chronology of a given area. This feature also works between the cadastral maps (possible different existing versions of these) and military surveys.
