DBF to MUIbase ============== PURPOSE MUIbase, a powerful relational programmable database that uses MUI as user interface, only has a simple import feature. Import and export is done by reading and writing ASCII files. Therefore the data you want to import must be in a special format described in the MUIbase documentation. This format is very simple, but it needs a lot of time to convert a database file format to this one. Since dBASE provides the most used database format on all platforms, I wrote a small utility to convert these files into MUIbase import files. The dBASE file (short: DBF) uses a simple format, but has some restrictions. This program is not only for use with MUIbase. Every program, that handles ASCII database files with field and record delimiters, can progress files generated by DBFtoMUIbase. DBFtoMUIbase is EMAILWARE. If you like it, send me a eMail (address see end of ReadMe). INSTALL Simply unpack the archive to anywhere you want. REQUIREMENTS - MUIbase 1.0 or higher USAGE DBFtoMUIbase is made for Shell usage. Following string shows the template: MUIBASEFILE=MBF/A/K,DBFFILE=DBF/A/K,NOQUOTES/S, RECORDDELIMITER=RD/K,FIELDDELIMITER=FD/K,FIELDS/S, LIMIT/K/N MUIBASEFILE=MBF/A/K This option specifies the name of the MUIbase import file to be generated. This file will be overwritten without request. DBFFILE=DBF/A/K The option DBF specifies the name of the DBF file to be converted. Currently the converter only handles DBF files of version 3 and files without an additional DBT file. NOQUOTES/S By default DBFtoMUIbase always surrounds the field names and field data by double quotes. When using this option you can supress quoting. If you do so, you have to switch off the option 'double quotes' in the import requester. RECORDDELIMITER=RD/K By default the converter uses the 'new line' character for delimiting the records. The option RD allowes you to set other record delimiters. The delimiter is a simple character or a C-style escape character like '\n' or '\t' (\x?? and \o??? are not allowed). You also have to use the same character in the import requester. FIELDDELIMITER=FD/K By default the converter uses the comma character for delimiting the fields in each record. The option FD allowes you to set other field delimiters. The delimiter is a simple character or a C-style escape character like '\n' or '\t' (\x?? and \o??? are not allowed). You also have to use the same character in the import requester. FIELDS/S In MUIbase you only can import data when you provide a field names line which *MUST* contain exactly the field names as used in MUIbase. This option prints the field names with type and size from the DBF file, but does no conversion. Using these informations you have to build a table in MUIbase which contain the printed same names (case sensitive!), types and sizes. The order of the fields is important too. LIMIT/K/N For testing purposes you can limit the records writing to MBF file. If you specify a number which is less than the number of records in the DBF file, the converter only writes as much records as specified here. It will always use the first records in file. A value of 0 is also possible; this only generates a line of field names using the field and record delimiters. NOTES Concerning MUIbase, DBF files have some restrictions as follows: · Field names are limited to 10 characters. · Duplicated field names are not explicitly excluded. This problem can be corrected by manually editing the concerning field names. · Memo fields are stored in a separate file with extension DBT (additionally to the DBF one). The converter does not handle these files and sets such fields to NIL. Try to change the memo field in the application writing the DBF file to a character field. · Texts containing double quotes will not be handled correctly. MUIbase then will terminate the import. To solve this problem, you manually have to correct such strings, so that the double quotes are really the beginning and end of a string. EXAMPLES Following converts a video database file 'video.dbf' to a MUIbase import file 'video.import': DBFtoMUIbase DBF=video.dbf MBF=video.import Same files, but without quotes: DBFtoMUIbase DBF=video.dbf MBF=video.import NOQUOTES Same files, but using tabulators instead of commas: DBFtoMUIbase DBF=video.dbf MBF=video.import FD=\t Next one shows the format of the DBF fields: DBFtoMUIbase DBF=video.dbf MBF=video.import FIELDS (unfortunately you also have to provide the option MBF; it only generates a empty file) Generates only a line of field names in 'video.import': DBFtoMUIbase DBF=video.dbf MBF=video.import LIMIT=0 DISCLAIMER THIS SOFTWARE IS PROVIDED BY THE AUTHOR AND CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

MISC This program is written in 4 hours, so suggestions and bug reports always are welcome, but I believe that the purpose of this program is fully accomplished. The conversion from MUIbase export files to DBF files is difficult, because MUIbase doesn't provide field formats ;-( Of course, watch the official MUIbase homepage at http://www.amigaworld.com/support/muibase/index.html BTW: Register MUIbase!
