A terminology database is a collection of terms with their corresponding translation in one or various other languages. The database can be mono-directional, meaning that its entries only work from one language to another, or multi-directional, which allow the translation of terms to occur between both languages interchangeably. Worbee Translator's databases are both multilingual and multi-directional: this means that not only can terms be translated in both directions, but one single term can have multiple translations in whichever languages are entered. One does not, for example, need to create separate entries for the same term from English into French and English into Italian: the same English entry can have its French and Italian correspectives, and one can also use the exact same term from French and Italian into English.
A terminology database is not to be confused with a translation memory: whereas translation memories store complete segments along with their translations, and are used to speed up translation by re-entering previously translated parts of the text automatically, terminology databases are collections of words which can be used as references and do not involve automatic population of the translation in the software.
A terminology database is neither to be confused with a dictionary, which provides a definition and various use contexts for the term in question. Terminology databases only feature the term and its unique translation in other languages, which makes them ideal for storing highly specialized terminology related to a particular field, for which one single translation is often available in a particular language.
