TABLESPACE_NAME | FILE_NAME | ALLOCATED_MB | FREE_MB | CAPACITY |
Is there way to store daily size of all table-space in another table automatically ? Actually i need to prepare checklist regarding table space on daily basis. So I wan't to create front end which email me the table space size details automatically on the basis of that table which store the information about table space size on daily basis..

Try the below query to get all tablespace details in oracle. Assuming that you have the necessary privileges to access dba tables.
SELECT a.file_name,
substr(A.tablespace_name,1,14) tablespace_name,
trunc(decode(A.autoextensible,'YES',A.MAXSIZE-A.bytes+b.free,'NO',b.free)/1024/1024) free_mb,
trunc(a.bytes/1024/1024) allocated_mb,
trunc(A.MAXSIZE/1024/1024) capacity,
a.autoextensible ae
FROM (
SELECT file_id, file_name,
tablespace_name,
autoextensible,
bytes,
decode(autoextensible,'YES',maxbytes,bytes) maxsize
FROM dba_data_files
GROUP BY file_id, file_name,
tablespace_name,
autoextensible,
bytes,
decode(autoextensible,'YES',maxbytes,bytes)
) a,
(SELECT file_id,
tablespace_name,
sum(bytes) free
FROM dba_free_space
GROUP BY file_id,
tablespace_name
) b
WHERE a.file_id=b.file_id(+)
AND A.tablespace_name=b.tablespace_name(+)
ORDER BY A.tablespace_name ASC;
Or
COLUMN TABLE_NAME FORMAT A32
COLUMN OBJECT_NAME FORMAT A32
COLUMN OWNER FORMAT A10
SELECT
owner, table_name, TRUNC(sum(bytes)/1024/1024) Meg
FROM
(SELECT segment_name table_name, owner, bytes
FROM dba_segments
WHERE segment_type = 'TABLE'
UNION ALL
SELECT i.table_name, i.owner, s.bytes
FROM dba_indexes i, dba_segments s
WHERE s.segment_name = i.index_name
AND s.owner = i.owner
AND s.segment_type = 'INDEX'
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.segment_name
AND s.owner = l.owner
AND s.segment_type = 'LOBSEGMENT'
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.index_name
AND s.owner = l.owner
AND s.segment_type = 'LOBINDEX')
WHERE owner in UPPER('&owner')
GROUP BY table_name, owner
HAVING SUM(bytes)/1024/1024 > 10 /* Ignore really small tables */
ORDER BY SUM(bytes) desc;
