No benefit to an application, yet takes up more disk space. Milliseconds, many times precision more than a second is just excessive and provides While some use cases necessitate the capturing of Similarly to integers, often times date and time datatypes are chosen that provideįar more detail than necessary. Reduce the ID column's footprint to 25% of its original value. There will be 200+ new states any time soon, it is safe to use a TINYINT instead and may provide a list of all 50 states in the US.Ĭommonly the ID for this table will be an INT data type, but since it is unlikely All of these types are available in SQL 2008+įor example, a table. Value being captured is never going to hit anywhere near that limit, using a SMALLINT (opens new window) for values up to 32,767 (2 bytes) or TINYINT (opens new window) for values up to 255 (1 byte) can drastically reduce storage space. With a size of 4 bytes, it isn't very big but can support numbers up to 2,147,483,647. INT (opens new window) is a common data type for IDs and whole-number numeric data. This advice is meant to be general and should always be assessed in the context of
By assessing the below options,Ī database can take up a fraction of its original size without sacrificing any actual data. # Design SmartĬommonly, databases are created using generic data types that may provide flexibility, butĪlso come at the cost of an increased storage footprint. Generally, the additional CPU required to decompress data that is read from disk is a worthwhile trade off for larger tables and indexes. In SQL Server 2016 SP1+, Express versions can utilize data compression (opens new window) on indexes and tables to increase the size of a database on disk.

Server Express is bundled with software, this can result in customer support calls and Of use it is not uncommon for a database to hit the ceiling on its size. This restriction has been in place for over a decadeĪnd has not increased over time, even as modern data storage has become extremelyĮven if an application doesn't require storing 10GB of data immediately, over years No single database can be over 10GB on modern versions. Limitations of SQL Server Express is the restriction on individual database sizes.
