    2 Announcing Dabo <Version>. 
     1May 1, 2004 
     2Announcing Dabo 0.1 
    33 
    44Dabo is a Python module, allowing for easy construction of 3-tier desktop 
    5 applications for distribution on Mac, Windows, and Linux. The 3 tiers are: 
    6  
    7     + The database, which can be any database with available dbapi modules. 
    8       Currently, Dabo only supports MySQL, but we intend to support very 
    9       soon: 
    10        
    11         + MySQL (already supported) 
    12         + PostgreSQL 
    13         + PySQLite 
    14         + Microsoft SQL Server and MSDE 
    15         + Oracle 
    16          
    17       This module abstracts the details of getting a database connection and 
    18       acquiring a recordset. SQL can be built piece-by-piece, allowing for 
    19       easy dynamic where clauses, for example. 
    20        
    21        
    22     + The business object, which abstracts the interaction with the database 
    23       tier and enforces business rules as set by your application code. Users 
    24       of the Codebook Framework for Visual Foxpro will feel right at home with 
    25       Dabo's bizobj class, as it uses the exact same API in most cases. 
    26        
    27        
    28     + The user interface, which can be any of several GUI's available for use 
    29       with Python. Currently, Dabo only supports wxPython, but we have left  
    30       open the possibility of supporting: 
    31        
    32         + wxPython (already supported) 
    33         + tkInter 
    34         + PyQt 
    35         + curses (text-UI could be useful for simple applications) 
    36          
    37        
    38       Dabo provides a host of useful UI base classes, including bizobj-aware 
    39       forms, data-aware controls (textbox, editbox, spinner, checkbox, etc.), 
    40       message boxes, and a data-browsing grid with incremental search built-in. 
    41        
     5applications for distribution on Mac, Windows, and Linux. The design allows 
     6easy separation of the database from the business logic from the user- 
     7interface. It should appeal to Windows developers, specifically Visual FoxPro 
     8and Visual Basic developers, as both principal authors come from a Windows 
     9database appdev background. 
    4210 
    4311The database layer can be used independently from the rest of Dabo, as can the  
    …… 
    4917which would allow you to distribute it for free with your GPL projects, or you  
    5018may purchase licenses for distribution with commercial or proprietary applications. 
    51 There is no warranty provided with Dabo, it is provided 'as-is'. 
     19We are also considering offering a FOSS Exception, which would keep your non- 
     20GPL'd Free and Open Source projects from getting infected with Dabo's GPL  
     21license. 
     22 
     23There is no warranty provided with Dabo, it is provided 'as-is'. Dabo is currently 
     24in a pre-alpha state of development. There is currently no official documentation, 
     25other than the source code.

    5327Dabo runs on Unix, Linux, Macintosh OSX, and Windows (all flavors). 
     28 
     29Currently, the only supported database backend is MySQL, but in the near future 
     30all dbapi databases will be supported, including PostGreSQL, Oracle, and MS-SQL. 
     31 
     32Currently, the only supported user-interface library is wxPython, but in the  
     33distant future we may support others, including PyQt, TkInter, Curses, and 
     34HTTP.
