keywords into several parts with the same number of digits (the number of digits in the last part can be different), and use the overlay sum (rounding) of these parts as the hash address, this method is called folding ). The hash address can be obtained by using the folding method when the number of each digit in a keyword is evenly distributed. For example, the hash address of the international standard library No. 0-442-20586-4 is as follows: 5. Except the remaining remainder The remainder o

Oracle Data Dictionary Overview Data dictionary is an important component of Oracle databases. It is a set of read-only tables used to record database information. The data dictionary contains: Definition of all schema objects in the database (including tables, views, indexes, clusters, synonyms, sequences, processes, functions, packages, triggers, etc) How much space the database allocates to a solution object and how much space the object currentl

In addition, bitmap is stored in a compressed format, so the disk space occupied is much smaller than that of B-tree indexes. Synonym (synonyms) A synonym is an alias for another data object. The public synonym is for all users. The private synonym is for only the object owner or the account granted permissions. Synonyms in

However, as mentioned earlier, since other natural language processing tools do not recognize underscores, if two words are used, you must use an open list, such as [physical, thing | x]. All predicates are used to convert the WordNet file instead of the original data. You can choose whether to use the complete database or its subset. WordNet is most directly used to find words. The predicate Lookup (+ word) searches for words from the wn_s.pl file and displays its syntax category
