Given the SQL Database as the following: CREATE TABLE t1 (id integer, name text); INSERT INTO t1 VALUES (generate_series(1,10000), ‘Noname’);   And the NoSQL Database in MongoDB as the following: Collection t1 {     { id: 1, name: “Noname” },     { id: 2, name: “Noname” },     { id: 3, name: “Noname” },      …      { id: 10000, name: “Noname” }, } Create the shell commands in MongoDB that are equivalent as the following SQL Command:   SELECT name FROM t1 WHERE id>1000; For example: SQL Command                                  MongoDB Shell Command SELECT * FROM t1;                          db.t1.find( ); or db.t1.find({ });
