Don's solution is working for given input with a assumption that file is sorted

You may try if output order is doesn't matter

Code:
$ cat file
Database1 Table1 column1
Database1 Table1 column2
Database1 Table1 column3
Database1 Table1 column4
Database1 Table2 Column1
Database1 Table2 Column2
Database2 Table1 Column1
Database2 Table1 Column2
Database2 Table1 Column3
Database2 Table2 Column1

Code:
$  awk '{A[$1 FS $2] = A[$1 FS $2] ? A[$1 FS $2] OFS $3 : $0}END{for(i in A)print A[i]}' OFS=\, file
Database2 Table1 Column1,Column2,Column3
Database2 Table2 Column1
Database1 Table1 column1,column2,column3,column4
Database1 Table2 Column1,Column2

if .. is needed then try
Code:
$ awk '{A[$1 FS $2] = A[$1 FS $2] ? A[$1 FS $2] OFS $3 : $0}END{for(i in A){gsub(/[[:space:]]/,"..",A[i]);print A[i]}}' OFS=\, file
Database2..Table1..Column1,Column2,Column3
Database2..Table2..Column1
Database1..Table1..column1,column2,column3,column4
Database1..Table2..Column1,Column2

for order sort like this
Code:
$ awk '{A[$1 FS $2] = A[$1 FS $2] ? A[$1 FS $2] OFS $3 : $0}END{for(i in A){gsub(/[[:space:]]/,"..",A[i]);print A[i]}}' OFS=\, file | sort -nk1
Database1..Table1..column1,column2,column3,column4
Database1..Table2..Column1,Column2
Database2..Table1..Column1,Column2,Column3
Database2..Table2..Column1

Note : use nawk on solaris

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
