LocalDB can act as an embedded database for a small application and SQL Server ExpressĬan act as a more robust, full-featured remote database engine for larger applications. Strives to be more of an exact match to other SQL Server versions from installation down toĭespite their differences, Microsoft still allows both to be used for production applicationsĪt no cost. While it can be usedįor the same purpose as LocalDB, it will consume more hardware resources to do so and Microsoft SQL Server 2012 Express with SP2 are a free, feature-rich editions of SQL Server that is ideal for learning, developing, powering desktop.

SQL Server Express, on the other hand, can be used for local development but requiresįar more installation and configuration time, stays on until it is manually turned off,Īnd can be installed many times on a single server or computer. This does not contain the database, but only the tools to manage SQL Server instances, including LocalDB, SQL Express, SQL Azure, full version of SQL Server 2012 Management Studio with SP2, etc. And by startingĪutomatically when an application connects, it only consumes resources necessary to runįor the duration of the connection, shutting off when no longer needed. Servers a very real need for developers to quickly and painlessly use a local database. As a result, it is only able to have one installation per version, runs in-process and not as a service,ĭoesn't stay running without active connections, requires a special connection string, and cannot be accessed remotely.īy providing the convenience of an embedded database with the compatibility of SQL Server, LocalDB To developers and less common for actual application use. I have updated the comparison table from the excellent discussion of the differences between Compact 3. However, LocalDB is intended for a different use case by addressing needs that are specific Now that SQL Server 2012 and SQL Server Compact 4 has been released, some developers are curious about the differences between SQL Server Compact 4.0 and SQL Server Express 2012 (including LocalDB).

SQL Server Express and LocalDB have a lot in common: LocalDB is packaged with Visual Studio (opens new window) as well as SQL Server Express (opens new window) (with Advanced Services for versions 2016 and earlier). The complexity for developing and testing applications with a SQL Server backend. Having the database access stay local greatly reduces The overhead of managing and installing a full SQL Server instance. No configuration to run and allows for quick access to a database engine without That can be turned on automatically when needed and turned off when not in use. LocalDB is a developer oriented, on-demand managed instance of the SQL Server engine
