Abstract: A method, system, and computer program product for managing data associated with a document stored in an electronic form. The document can be a part of a file. Computer processed algorithms, user-operated computer graphics tools, or both can be used to derive data from or assign data to the document or the file. First data is derived from the document, second data is assigned to the document, or both. The first data, the second data, or both are organized as attributes of an object of a first computer database. At least one attribute is organized as a child object of the object. The at least one attribute is associated with a feature of the document. Optionally, an attribute is moved from the object of the first computer database to an object of a second computer database and an address of a location in a memory at which the object of the second computer database is stored is added as a new attribute of the object of the first computer database.

Abstract: The novel acylated guanidines, ureas and substituted ureas correspond to the general formula: ##STR1## in which R.sub.1 repesents a substituted or unsubstituted aromatic ring, R.sub.2 represents an alkyl, aryl, or arylalkyl group, R.sub.4 repesents hydrogen or a variously substituted aryl group, X is oxygen or an imine group: NH and Y represent an alkyl aryl alkyloxy or aryloxy group or a hydrogen atom when X represents oxygen or the group COR.sub.3 with R.sub.3 representing an aromatic group, an aryloxy, aralkyloxy or alkyloxy group when X represents the NH group. They are prepared by heating an appropriate compound under reflux with an oxyaminoalcohol, in a suitable solvent. The products are useful as medicaments for the treatment of arterial hypertension, ischemica diseases of the heart and rhythmic disorders of the latter.
