Background
Old reference chemistry databases were
not well organized.
 The reference chemistry databases need
to be well documented to support quality
control program.
 “Sloppy records and poor records
maintenance likely reflect poor quality
control in other areas of operations and
will give that impression to others".
(Garfield, 1991).

Objective
 To
develop well organized reference
chemistry databases as part of
quality control program.

 Structure
of Reference Chemistry DB
consist of 5 tables for both Soybeans
and Corn databases.
 The databases were build in
Microsoft Access.

Step to build new databases
1.

4.
The old reference chemistry databases
are organized and separated according
to the table that will be build. (in Excel)
Additional information are added to the
new table, such as date of the test and
Lab doing the test.
The individual files such as calibration,
oven moisture, density might be useful
to find information about the samples.
The new databases in the Excel are
imported to the Access.

Save Sheet in Excel in “webpage format”
(This will be table in Access).
Open Access, Click Get External DataLink Table.
When the dialog box appears, choose
“html document” for the file type.
Select table that you want to connect.
Follow step in the dialog box, before you
finish, click “advanced” to make sure the
field data type are right.

How to add/update data

Find the respective files for each table, for example:
To update Master table, use the calibration file for the
respective year.
To update Proximate table, use the Proximate Results from
Eurofins (In the Completed form Folder) for the respective
year.
Copy the files to the Excel Databases according to field
available, you may need to arrange the file before making
a copy to Excel Databases.
Save the file as the table name in “webpage” format.
For example: If you update Proximate table, save
“Proximate” sheet in Excel as webpage format, choose
“selection sheet”, save as “Proximate”, it will replace the
existed file.
Notes: every table in database is linked to the webpage file,
but to update, you need to use Excel database.
Update File
How to add the data
 Another
way to add the data is to
type the new data directly to the
Access. (This is so time consuming).
