Option A is true. SQLite, like most relational database systems, assigns a type to each column in a table. The data types supported by SQLite include INTEGER, REAL, TEXT, BLOB, and NULL.
Option B, Option C, and Option D are all false. SQLite supports LEFT OUTER JOIN, but it does not support RIGHT OUTER JOIN or FULL OUTER JOIN. Therefore, Option B and Option D are both incorrect. On the other hand, Option C is incorrect because SQLite does support JOINs and therefore, it supports OUTER JOINs as well.
Option E is false. SQLite supports the creation of views, which are virtual tables based on the result-set of a SELECT statement. Views can be used to simplify queries, encapsulate complex logic, and enhance security by granting users access to specific columns rather than the entire table.
In summary, Option A is true, Options B, C, and D are false, and Option E is false.
