+<concept id="GUID-EFA822E0-BE80-5EB8-82E5-1659BDB1BDD9" xml:lang="en"><title>Named
+database</title><shortdesc>Describes how databases can be created and opened using the database
+name.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>In order to support the DBMS client-server interface, the <codeph>RDbNamedDatabase</codeph> class
+provides the interface for creating and opening databases identified by name.</p>
+<p>The mechanism is generic; the database is identified by its name and the
+database format. The format is a name that is used to identify the implementation
+used for creating or opening that database. There is a default format, which
+has the name "epoc". The default format is a store database in the root stream
+of the database file.</p>
+<p>If required, other formats can be provided in extension DBMS driver libraries.
+These formats need no be file-based. Additional DBMS driver libraries are
+dynamically bound to the API at run-time, if one can be found to support the
+format requested.</p>
+<p>Formats which are UidTyped files, such as the default, can allow the client
+to specify a 3rd Uid by extending the format name with the Uid name (as generated
+by the <codeph>Name()</codeph> member function of <codeph>TUid</codeph>, an
+8 digit hexadecimal number enclosed in square brackets).</p>
+<p>If specified, this is also checked when a database is opened. e.g. creating
+a FileStore database “C:\My Database” with a 3rd Uid of 0x10001234:</p>
+<codeblock id="GUID-2291B3E7-D3D5-5E99-8ACA-886163557978" xml:space="preserve">_LIT(KMydatabase,"C:\\My Database");
+_LIT(KDemoUid,"[10001234]");
+RDbNamedDatabase database;
+TInt r=database.Create(fs,KMydatabase,KDemoUid);</codeblock>
+<p>For comparison, the equivalent code required to create an <codeph>RDbStoreDatabase</codeph> in
+the root of a <codeph>CPermanentFileStore</codeph> would have been:</p>
+<codeblock id="GUID-B103A01B-55C0-50B5-81F7-F2763E5E16DB" xml:space="preserve">_LIT(KMydatabase,"C:\\My Database");
+CFileStore* fstore=CPermanentFileStore::ReplaceLC(fs,KMydatabase,EFileWrite);
+fstore-&gt;SetTypeL(TUidType(fstore-&gt;Layout(),KDatabaseUid,TUid::Uid(0x10001234)));
+RDbStoreDatabase database;
+fstore-&gt;SetRootL(database.CreateL(fstore));
+fstore-&gt;CommitL();</codeblock>
+<p>A named database may be encrypted; the default is an un-encrypted database.</p>
+</conbody></concept>
