MAGISTRAL

SOFTWARE PACKAGE INCLUDES

• original object oriented network data base, which is characterized by high speed performance of main operations (searching, selection, sorting) when the information volume is about 5--7 Ìb (about 10000--20000 records). The hierarchical structure of forms allows to find quickly the information concerning any network object. The using of extended patterns provides the selection of records by the full set of fields simultaneously. Wide using of 'hot keys' makes the exploitation quick and convenient. Package have high degree of reliability. In particular, it can be used in special mode to avoid accidental changes.
• high performance map supporting system, that allows user to choose arbitrarily the list of geographic layers (in part, hydrography, frontiers of regions, areas and republics) , to define the palette, to change the scale. Problems of managing the screen are solved efficiently. The plenty of geographic objects is chosen automatically without dependence on the current scale; it excludes the situations the screen is overloaded by the information.
• the subsystem of visualization of network data. All the objects are put on the map by pictograms and colors reflecting their parameters. List of parameters to visualize is elected by user himself; he have an opportunity to point whether the names of towns or codes of trunk lines and nodes are typed near corresponding objects. The special means is created for the more complicated objects,- nodes and trunk lines. This is structure scheme which ascribes the object itself and its interconnection with adjacent elements: telephone network directions, links of trunk lines and nodes. Vast menu allows to change widely level of detail of scheme.
• All subsystems are naturally included into the united multywindows integrated environment, that supports the independent settings of regimes in different windows, an ability of arbitrary changing of their dimensions and location, abilities of sorting, hiding and showing again on the screen. All actions may be performed using 'mouse'-device. The principles of dialogue are not too far from these in MS-Windows.
