Working with Large Data Sets
2-199
Export Large Data Sets from MATLAB
When inserting large volumes of data into a database, you might experience slow
processing. To achieve the fastest performance, use the appropriate function to insert the
data.
If you are using native ODBC, use the fastinsert or insert function for fastest
processing. If you are using a JDBC driver, use datainsert for the fastest processing to
export your data from MATLAB.
For a comparison of these functions, see “Inserting Data Using the Command Line” on
page 2-197.
Access Data Stored in a Database Using a DatabaseDatastore
An alternative for importing large data sets in a database into MATLAB is using a
DatabaseDatastore. A DatabaseDatastore is a datastore that contains a collection
of data stored in a database. You can use MapReduce to analyze large data sets stored in
a DatabaseDatastore object. For details, see “Working with a DatabaseDatastore”.
