Sequence: provides regular values. Database objects that can be used by multiple users to generate unique values are mainly used to provide primary key values. Index: Improves query efficiency. Synonym: alias for the object. In MYSQL and SQL SERVER databases, the

1. Why Use synonyms: Synonyms, as the name implies is two words, the same meaning, can replace each other. So what's its function? A one of the most obvious purposes is to simplify SQL.

For example, to find a table in another schema, you need to prefix the table name with the schema name. If

(i) the concept of synonyms Synonyms are aliases for tables, views, indexes, or other schema objects in a database, similar to views, where synonyms do not occupy the actual storage space, and only the definition of synonyms in the data dictionary. When you develop a database, you should avoid referencing tables, views, or other database objects directly, otherwise, when the structure of the table changes, it will affect the use of the application, this time need to recompile the program, if you

1. Introduction Due to the limitations of the search algorithm itself, the user's semantic and intent understanding is not enough, and the click adjustment based on user behavior is used as a supplement to the traditional search algorithm, it plays an important role in search. Although user behavior has been proven to be effective in the search, it remains at the query-URL level or the Ngram-URL level [1] without in-depth feedback on the basic policies in the search algorithm, for example, synon

seen as an alias for an object, just like an alias for a command in the Liunx operating system. But the Linux command alias only provides the benefit of easy memory.1. In Oracle, synonyms can be used to:1) Simplify the SQL statements entered in Oracle, and by creating synonyms for objects, we can simplify complex SQL statements for easy memory and manipulation2) Hide the name and owner of the object, create synonyms for the object, such as the EMP table in Scott Mode (SCOTT,EMP), we create a
