     6 What is  `Google AppEngine` ?

     7 ------------------------------

     8 

     9 `Google AppEngine`_ is provided with a partial port of the `Django`

    10 framework, but Google stated at Google IO 2008 that it would not

    11 support a specific Python web framework and that all

    12 community-supported frameworks would be more than welcome [1]_. 

    13 

    14 Therefore `Logilab`_ ported `CubicWeb` to run on top of `Google AppEngine`'s

    15 datastore.

    22 Essentials

    23 ----------

    24 

    25 To build a web application for `Google App Engine`'s datastore, you

    26 need to have a good understanding of the main concepts of our 

    27 `CubicWeb` framework.

    28 

    29 The main concepts are:

    30 

    31   - *schema*

    32 

    33   - *query language*

    34 

    35   - *result set*

    36 

    37   - *views*

    38 

    39   - *generated user interface*

    40 

    41   - *cube*

    42 

    43 You can find detailled explanation of those concepts in :ref:`TermsVocabulary`.
