Source Code of an object

Question

Hello there,
I was wondering is there any way to know what was the sql statement used to create a object in the past. I mean to say is there any table which stores the sql command.
Eg. if we create the table the Source of the table like " Create Table Xtable( No number, name varchar2(5));"
Will this sql statement get stored in any table ? so that if I want to view it later on or maybe another person/DBA wants to view it in future will know what was the statement.
Regards.

... or use DBMS_METADATA :
SQL> set long 100000
SQL> select dbms_metadata.get_ddl('TABLE','EMP','SCOTT') from dual;
DBMS_METADATA.GET_DDL('TABLE','EMP','SCOTT')
  CREATE TABLE "SCOTT"."EMP"
   (    "EMPNO" NUMBER(4,0) NOT NULL ENABLE,
        "ENAME" VARCHAR2(10),
        "JOB" VARCHAR2(9),
        "MGR" NUMBER(4,0),
        "HIREDATE" DATE,
        "SAL" NUMBER(7,2),
        "COMM" NUMBER(7,2),
        "DEPTNO" NUMBER(2,0),
         CONSTRAINT "EMP_PK" PRIMARY KEY ("EMPNO")
  USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
  PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
  TABLESPACE "USERS"  ENABLE,
         CONSTRAINT "DEPT_FK" FOREIGN KEY ("DEPTNO")
          REFERENCES "SCOTT"."DEPT" ("DEPTNO") ENABLE
   ) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
  STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
