I'd be curious to discover the way the major databases compare when it comes to recognition. What amount of the market does Oracle have? Just how much does MS SQL have? MySQL, PostGre, ...? So how exactly does this breakdown within the more compact marketplaces (e.g. small web applications, large web applications, huge corporate services,...)?

I am searching for statistics here. Not impressions.

Thanks.

Note: I'd say the amount of programs/projects with different given db will be the way of measuring recognition.

Javier's given an answer not every that different in spirit from mine - some questions. However the questions listed here are slightly different:

  • The number of copies distributed?
  • How much cash received?
  • Amount of data under management?
  • Amount of non-duplicated data?

The very first measure most likely favours outdoors source items the 2nd favours the greater costly the 3rd favours the mainframes the 4th penalizes Google. A mix of the 2 teams of questions provides you with enough concern to see the right path with the various documents that provides you with their spin around the amounts.

Gartner was once a resource of these information other similar analyst firms can most likely also help. I am unsure if the VLDB site has much to assist. Google "dbms share of the market" pops up with Gartner - I made use of it to verify my memories.

From Oracle website, they're # 1.

Gartner 2008 Worldwide RDBMS Share Of The Market Reviews 48.9% Share for Oracle (*)

Gartner has released their share of the market amounts by operating-system for 2008 according to total software revenues. Based on Gartner, Oracle

The large three DBMS suppliers stay the same: Oracle then IBM then Microsoft. Following the large three, # 4 is Sybase with 3.5% share of the market and # 5 is Teradata with 3.3% share of the market.

i haven't any source, however i reckon that anybody you request may have different solutions for various definitions of 'popularity', for instance:

  • quantity of designers that develop from this DB
  • quantity of DB admins which use this DB
  • quantity of shops running this DB
  • quantity of servers by using this DB
  • quantity of programs running on the top of the DB
  • quantity of records handled about this DB
  • quantity of customers offered by applications about this DB

during my totally noninformed view, i'd reckon that the very first definitions favor SQLite or MySQL, as the last couple of favors Oracle

To sum up: a "hard question to reply to.Inch Gartner clearly measures revenue, which skews by cost and minimizes open-source usage. However, other DBMS can claim high usage share because they are baked into programs (like SQLite in apple iphones, Postgre in 'cisco' hubs, MS SQL Server in Sharepoint, etc). Therefore it most likely is dependent available on the market segment: e.g. SQLite will most likely not be a large player in data warehousing!
