摘要

The use of databases is an appropriate approach that helps in organising modern cartographic work, especially covering production and maintenance of electronic charts. However, the databases should be used when the data domain (or its' subset at least) is properly formalised and the formalisation language is suitable for the database engine. Attempts to use databases and formalisation languages outside of the scope of their applicability leads to the uncertainty on how the information is entered, organised and maintained, thus making the advantages of the database approach quite awkward. 'Single unified' databases that claim to be a universal solution for cartographic data production are not really single and universal because there are no traditional (native) database tools capable of maintaining the information consistency. The complexity of the hydrographic reality phenomenon is too high for tools and technologies available as database solutions today. Such complexity is the main driving force for the creation of new algorithmic tools targeted at maintaining the information consistency and efficiency of the entire solution. The author believes that the optimal solution can be elaborated, but the search for a solution should not be substituted with the search for or use of handsome but delusive means.
