Geodaten German Admin 12.00

The database contain geodata of the Federal Republic of Germany with geo referenced towns, municipalities, town quarters, administrative units, postal codes, telephone preselections, nature areas and landscapes. The data contain coordinates for navigation and geo-coding, proximity searches and distance computations and for the mapping of nature area and landscape information. Quite often it is necessary to reference an address field e.g. like town or municipality name, postal code or telephone preselection, to corresponding geographical data and coordinates - a Geo Reference. The geo reference can be used for example to direct a customer to the closest store locations of a retail store chain by doing a proximity search. Another possibility it to determine distances between the different objects of the database tables with the included geo references. With the elevation data from a Digital Elevation Model the ground level height of each place can be determined. Often the knowledge is necessary about affiliations and relationships between data derived from different hierarchies. So it can be determined to which federal state, governmental area or governmental county a town, a postal code or a telephone preselection is associated. It is possible to assign a variety of natural and scenic information to each town or municipality. The information is available in different database tables, witch can be linked together by included keys. ORTREF: 12.500 Towns and Municipalities with geo references. ORTGEM: 12.500 Towns and Municipalities without geo references. ORTTLREF: 105.000 Town Quarters with geo references. ORTTLGEM: 105.000 Town Quarters without geo references. PLZREF: 32.000 Postal Codes with geo references. PLZGEM: 32.000 Postal Codes without geo references. VORWREF: 20.500 Telephone Preselections with geo references. VORWGEM: 20.500 Telephone Preselections without geo references. KREIS: 450 Administrative Countys. NATRAUM: Nature Area Classification.

Organic Chemistry 2.0

Organic Chemistry drills students by presenting problems on products of reactions, reactants required for a reaction, naming of organic compounds, structural formulae and identifying compounds as belonging to a particular homologous series. The registered versions permit users to select whatever group or groups they want to work with from: alkanes, alkenes, alcohols, alkyl chlorides, amines, aldehydes, ketones, carboxylic acids, esters, amides and acyl chlorides. The shareware version deals with alkenes. There is also a Pro version. A help file provides assistance for the program and contains student notes on the functional groups, naming, preparations, reactions etc. Requires: the file VBRUN300.DLL
