+Data Binding
+------------
+
+There are various ways to bind application level data structures to CQL statements:
+
+* You can write the data binding by hand, as outlined in the Tweet example. This provides you with the greatest flexibility, but it does mean that you need to keep your application code in sync with your Cassandra schema.
+* You can dynamically marshal an entire query result into an `[]map[string]interface{}` using the `SliceMap()` API. This returns a slice of row maps keyed by CQL column mames. This method requires no special interaction with the gocql API, but it does require your application to be able to deal with a key value view of your data.
+* As a refinement on the `SliceMap()` API you can also call `MapScan()` which returns `map[string]interface{}` instances in a row by row fashion.
+* The `Bind()` API provides a client app with a low level mechanism to introspect query meta data and extract appropriate field values from application level data structures.
+* Building on top of the gocql driver, [cqlr](https://github.com/relops/cqlr) adds the ability to auto-bind a CQL iterator to a struct or to bind a struct to an INSERT statement.
+* Another external project that layers on top of gocql is [cqlc](http://relops.com/cqlc) which generates gocql compliant code from your Cassandra schema so that you can write type safe CQL statements in Go with a natural query syntax.

-* [cqlc](http://relops.com/cqlc) generates gocql compliant code from your Cassandra schema so that you can write type safe CQL statements in Go with a natural query syntax.
 * [gocqldriver](https://github.com/tux21b/gocqldriver) is the predecessor of gocql based on Go's "database/sql" package. This project isn't maintained anymore, because Cassandra wasn't a good fit for the traditional "database/sql" API. Use this package instead.
