Comparing &kexi; to other database applications
|
|
</title>
|
|
<para>
|
|
Although different database applications tend to provide similar
|
|
functionality, they often use different terminology. For your
|
|
convenience, this appendix shows how the terminology used in
|
|
&kexi; corresponds to that used by other database applications.
|
|
Thus, this chapter may be useful when migrating databases from
|
|
one application to another.

Data types

<para>
|
|
The table below shows how the data types in &kexi; correspond
|
|
to data types in other database applications.
|
|
</para>
|
|
<para>
|
|
Some of the data types listed here are
|
|
<firstterm>sub-types</firstterm> of other types. For example,
|
|
the <emphasis>Long text</emphasis> type is a sub-type of the
|
|
<emphasis>Text</emphasis> type. To use a sub-type in
|
|
&kexi;, you should select the corresponding basic type (in
|
|
this case, Text) in the table designer, and then select the
|
|
sub-type using the <guilabel>Subtype</guilabel> setting in the
|
|
<guilabel>Properties Editor</guilabel>.
