-<p>Apache Gora is an Object Datastore Mapper which has its own data model. At
the same time, Apache Pig has its own data model too. Because of this, it is
needed an adaptation between both data models.</p>

+<p>Apache Pig is a platform for analyzing large data sets that consists of a
high-level language for expressing data analysis programs. With the module
gora-pig we allow to operate on the data from Pig scripts using Apache Gora as
storage.
+The objective of this document is to describe the approach taken to implement
a Pig adapter for Gora and show how to load/store the data.</p>
<p>Warning: Not all Gora modules are adapted to be used under Pig, since they
have to implement loading the mapping defined from gora properties with the key
"gora.mapping". At this moment are adapted <strong>gora-hbase</strong> and
<strong>gora-kudu</strong>.</p>

-<p>Gora's data entities are generated from Apache Avro schemas, and inherits
the same datatypes defined in Avro. Pig has its own data model.</p>
+<p>Apache Gora is an Object Datastore Mapper which has its own data model
inheriting Avro data types, and Apache Pig has its own data model. Because of
this, it is needed an adaptation between both data models.</p>
<p>The following tables shows the different types and a possible conversions
between Gora and Pig types.</p>
