Most DBMS's will support these two syntaxes:
CREATE VIEW view_name AS SELECT col1, col2, col3 FROM table_name WHERE condition;
Where column names are just copied from the query
and:
CREATE VIEW view_name (colA, colB, colC) AS SELECT col1, col2, col3 FROM table_name WHERE condition;
Where column names are specified.

The two main approaches are Materialized Views and Indexes. Materialized views store the results of the query in a physical table to improve query performance, while indexes are data structures that enhance the speed of data retrieval by providing quick access to rows in a table based on the values of one or more columns.
