MS SQL 2005 : To Check the size of the Database

Use the Below Query to Check the Database Size with all *.mdf & log.*ldf file sizes

****QUERY****

SELECT DB_NAME(database_id) AS DatabaseName,
Name AS Logical_Name,
Physical_Name, (size*8)/1024 SizeMB
FROM sys.master_files
WHERE DB_NAME(database_id) = 'Database_Name'

RETURNS DATETIME
    WITH SCHEMABINDING
AS

MS SQL - Standby Servers and Types of Standby Servers

Standby servers - Standby Server is a type of server that can be brought online in a situation when Primary Server goes offline and application needs continuous (high) availability of the server. There is always a need to set up a mechanism where data and objects from primary server are moved to secondary (standby) server. This mechanism usually involves the process of moving backup from the primary server to the secondary server using T-SQL scripts. Often, database wizards are used to set up this process.

Languages for BI – MDX, DMX, XMLA

BI stands for Business Intelligence 

What languages BI uses to achieve the goal? 

MDX – Multidimensional Expressions. This language is used for retrieving data from SSAS cubes. It looks very similar to T-SQL, but it is very different in the areas of conceptualization and implementations.

DMX – Data Mining Extensions. This is again used for SSAS but rather than cubes it is used for data mining structures. This language is more complicated than MDX. Microsoft has provided lots of wizards in its BI tools, which further reduced experts for learning this language which deals with data mining structures.

XMLA – XML for Analysis. This is mainly used for SSAS administrative tasks. It is quite commonly used in administration tasks such as backup or restore database, copy and move database or learning meta data information. Again, MS BI tools provide lots of wizards for the same.
