Re: [libreoffice-users] entering records

Hi :)
Errr, you know you can write your reports in Writer rather than in Base?  It gives a lot more 
flexibility that way.  You 'just' need to connect your Writer document to the database.  Errr, that 
is where i get stuck though as i don't know how to do that yet! :(  

With database programs in general it is "best practice" to build Forms and Reports from Queries, 
rather than directly from Tables, because it gives more flexibility and makes it easier to fix 
if/when accidents happen (such as the back-end suddenly vanishes making the Forms freak out) or 
when the table needs to grow or change.  A Query can be a simple as "show all the data from the 
Table".  Obviously the Query itself doesn't hold any of the data, it's just an abstraction so it 
forms a buffer between the Table and the Forms and Reports.  It can be useful to have it do some 
"filtering or "sorting" so that by the time the Forms or Reports are looking at the data it's all 
neatly sorted already.  

With Base a lot of weird things go wrong when using the internal back-end to hold the data in the 
Tables.  It is really designed to be used with an external back-end.  This makes it highly 
scalable.  There are a lot of big, powerful back-ends such as MySql/MariaDB, PostgreSQL or smaller, 
lighter faster ones (although the only ones i have heard of are Java-based ones such as HsqlDB).  
Apparently PostgreSQL has the best support in terms of their devs supporting Base although people 
on this list put a lot of work into the connectors or MySql/MariaDB and they are easier to contact. 
 Someone recently surprised me by saying that his MySql back-end was extremely fast so maybe it is 
good for small amounts of data too and not just large, hefty tables.  

There is some documentation about Base but it's slow going.  The most complete is on the Faq page
https://wiki.documentfoundation.org/Faq
but the handbook is getting really close too now
https://wiki.documentfoundation.org/Documentation/Publications#LibreOffice_Base_Handbook
That 2nd link also gives you the Base Guide's first few chapters which is a lot heftier as you will 
notice.  

Sorry that none of this directly answers your question!  Hopefully others will be around soon that 
can help more directly
Apols and regards from 
Tom :)
