Volumetria Base de Dados

Oi pessoal,
Alguem já precisou fazer a estimativa de crescimento da base?
Pesquisei bastante, mas só achei algo meio genérico e não entendi muito bem.
Eu usei esses script's, mas não sei se isso é o suficiente.
-- Retorna o tamanho da base
SELECT DB.name, SUM(size) AS Tamanho FROM sys.databases DB
INNER JOIN sys.master_files
ON DB.database_id = sys.master_files.database_id
GROUP BY DB.name

-- Retorna a quantidade de coluna de cada tabela e o tamanho maximo.
select o.name
, count(*) Colunas
, sum(case when max_length = -1 then 0 else max_length end) TamanhoMax
from sys.objects o
join sys.columns c
on o.object_id = c.object_id
where o.type ='U'
and is_ms_shipped = 0
group by o.name
e criei essa procedure

Oi Simone, Bom dia!!!

Acho interessante acompanhar o crescimento sim.

Se nao me engano ja houve algumas discursoes aqui no forum a respeito de monitorar o tamanho das base e houveram algumas dicas.

Eu sugiro verificar os blog dos Junior Galvao http://pedrogalvaojunior.wordpress.com/ , muuito bom, e acho que deve ter alguma sugestao la, e do Gustavo Maia http://gustavomaiaaguiar.wordpress.com/, SQL From Hell, e outros.

Espero ter ajudado.

Abraco.

acompanhando o post, essa questão de volume do banco de dados me interessa. esse SQL From Hell ja tinha add nos meus favoritos, esse outro não conhecia.

Alex, obrigada, vou dar uma olhada.

Jefferson, achei muito interessante esses script's, é sempre bom acompanhar essas coisas.
Mais não é bem isso que preciso, mas muito obrigada, já salvei os scripts e certeza que vou utiliza-los.
