+# Globally Distributed Database Schema Design 
+
+## Data Distribution Schema Design - Creating Sharded Tables
+
+Sharded tables can be created in the following distribution methods:
+
+- <b>System-Managed Data Distribution</b>: data is automatically distributed across the shards using partitioning by consistent hash;
+
+- <b>User-Defined Data Distribution</b>: User explicitly maps data to individual shards. A sharded table in a user-defined distributed database can be partitioned by range or list and no tablespace sets are created;
+
+- <b>Composite Data Distribution</b>: is a combining of the two previous methods. Composite data distribution method allows you to partition subsets of data that correspond to a range or list of key values in a table partitioned by consistent hash.
