6 <li>Today, our goal is to be compatible with .NET 1.1 and .NET 1.0. We also would like
7 to extend data access beyond what is included with .NET 1.0 and .NET 1.1,
8 such as, include access to more databases, such as, PostgreSQL and MySQL,
9 but also provide classes that help in creating data source-agnostic code, such as,
10 Mono.Data.ProviderFactory.</li>
12 <li>In the future, we would like to be compatible with .NET 1.2. This includes features
13 like <a href="http://longhorn.msdn.microsoft.com/lhsdk/ndp/daconworkingwithobjectspacesarchitecture.aspx">ObjectSpaces</a></li>
17 ** Bugs and Feature Requests
21 <li>Bugs with Mono or any data provider in Mono should be reported
22 in Mono's Bugzilla <a href="http://bugzilla.ximian.com/">here</a>. If you
23 do not have a Bugzilla user account, it is free
25 one <a href="http://bugzilla.ximian.com/createaccount.cgi">here</a>.</li>
27 <li>Any requests for new features or missing functionality
28 can entered as a bug in Bugzilla too</li>
32 ** ADO.NET Data Providers
34 <p>Mono has many ADO.NET Data Providers to get you connected:
37 <li><a href="http://www.go-mono.com/ibmdb2.html">IBM DB2 Universal Database</a></li>
38 <li><a href="http://www.go-mono.com/mysql.html">MySQL</a></li>
39 <li><a href="http://www.go-mono.com/odbc.html">ODBC</a></li>
40 <li><a href="http://www.go-mono.com/oracle.html">Oracle</a></li>
41 <li><a href="http://www.go-mono.com/oledb.html">OLE DB</a></li>
42 <li><a href="http://www.go-mono.com/postgresql.html">PostgreSQL</a></li>
43 <li><a href="http://www.go-mono.com/sqlclient.html">Microsoft SQL Server</a></li>
44 <li><a href="http://www.go-mono.com/sqlite.html">SQL Lite</a></li>
45 <li><a href="http://www.go-mono.com/sybase.html">Sybase</a></li>
46 <li><a href="http://www.go-mono.com/tdsclient.html">Older Microsoft SQL Server and Sybase databases</a></li>
49 <p>External Projects that have created ADO.NET Providers that work on Mono:
53 <li><a href="http://www.go-mono.com/firebird.html">Firebird Interbase</a></li> is a
54 Firebird SQL Managed data provider. It can be used with Interbase databases too. It
55 is written in 100%C# and does not require a client library. Works on .NET and Mono.</a>
56 <li><a href="http://gborg.postgresql.org/project/npgsql/projdisplay.php">Npgsql</a> is a
57 PostgreSQL Managed data provider written
58 in 100% C#, does not require a client library, and works on .NET and Mono</li>
59 <li><a href="http://sourceforge.net/projects/mysqlnet/">MySQLNet</a> is a
60 MySQL Managed data provider written in 100% C#, does not
61 require a client library, and works on .NET and Mono</li>
66 <p>Some tools that can be used for ADO.NET and other technologies (ASP.NET, XML, etc).
71 <li>SQL# is a command line query tool included with Mono to enter and execute SQL statements</li>
76 <li>XML Schema Definition tool</li>
78 <li><b>XDR to XSD</b> - used to generate an XML schema from an XDR (XML Data Reduced schema) file.
\r
79 XDR was used by Microsoft prior to XSD becoming a W3C recommendation. So, this needs
\r
80 to be supported for legacy reasons</li>
\r
81 <li><b>XML to XSD</b> - used to generate an XML schema from an XML file</li>
\r
82 <li><b>XSD to DataSet</b> - used to generate DataSet classes from an XSD schema file. The
\r
83 DataSet classes created can then be used with XML data</li>
\r
84 <li><b>XSD to Classes</b> - used to generate classes from an XSD schema file. The
\r
85 classes created can be used with System.XML.Serialization.XMLSerializer
\r
86 to read and write XML code that follows the schema</li>
\r
87 <li><b>Classes to XSD</b> - used to generate an XML schema
\r
88 from type(s) in a assembly file. The
\r
89 XML schema created by the tool defines the XML format used
\r
90 by System.XML.Serialization.XMLSerializer</li>
\r
97 ** Extra Classes in Mono ADO.NET
99 <p>An ADO.NET <a href="http://www.go-mono.com/provider-factory.html">Provider Factory</a>
100 was created by Brian Ritchie. The
101 Provider Factory is a way to dynamically create
102 connections, commands, parameters, and data adapters based on configuration
105 ** Database Access from ASP.NET
107 <li>Take a look at xsp in cvs and look at the examples in test: dbpage1.aspx
110 <li>Notice that the namespace System.Data is imported via <b>import</b></li>
111 <li>A NameValueCollection is gotten using ConfigurationSettings.AppSetings. These
112 settings are gotten from the file server.exe.config which is a XML file. The XML
113 file has a section appSettings. In the appSettings section, you have keys
114 for DBProviderAssembly, DBConnectionType, and DBConnectionString.
116 <li><b>DBProviderAssembly</b> is the assembly of the ADO.NET provider.
119 <li><b>DBConnectionType</b> is the System.Type of the class that
120 implements System.Data.IDbConnection that is found
121 in the DBProviderAssembly.
123 "ByteFX.Data.MySqlConnection"</li>
124 <li><b>DBConnectionString</b> is the ConnectionString to set to the
125 IDbConnection object to use in opening a connection to a data source.
127 "hostaddr=127.0.0.1;user=monotest;password=monotest;dbname=monotest"</li>
129 <li>The function GetConnectionData() gets the database provider assembly, connection type,
130 and connection string parameters if they exist; otherwise, it uses default values. This is
131 done during the loading of the web page.</li>
132 <li>With the connection parameters, the assembly is loaded, the connection type is verified that
133 it implements IDbConnection and an instance of the class can be created, creates a instance
134 of the class, sets the connection string, and opens the connection.</li>
142 <li>Testing connection-oriented classes are done
143 via the provider specific tests
144 found in the mcs source at mcs/class</br>

180 done via mono's modified version of NUnit.
182 <li>To run all the NUnit tests for Mono, you need the mcs source. cd to the root
183 of the mcs source. To run it:

189 the mcs source at class/System.Data/Test and run it:
