Microsoft Access Database Software Is The Best For Storing Your Data.
Over the years of programming Microsoft Access, some best tips and practices have been found out that are the most important in developing the best database. If these rules were violated, it could cause errors, slow performance, database corruption and other difficulties in database work.
So, in order to improve the form performance and the loading of drop down list, you should use optimized by Access stored queries as the sources for your records. The Access wizard will create form with Select SQL record sources and this is not the best option.
In order to prevent errors in data entry, make the possibility of what information can be entered in a field restricted. You can use a message window or onscreen area to inform the use what is required. In order to increase the performance speed, index the criteria selection fields in your queries and fields in queries that are linked to the tables. Another way to increase the speed of processing is to use the least amount of memory and place by optimizing the data types.
Add code error handling to routines, in order to know what logic to apply. When an MDE file stops working, it won’t inform you about anything useful on how to fix the error.
Give your users the access only to the copy of the front end database. It will contain everything except for the data. By restricting access to the original front-end database, you will prevent the possibility of unexpected database corruption. Make sure you always split the database into back end and front end. The back end data should be placed on the network share root, which will make it quicker to read it and write. And don’t forget to compact the back end data regularly. This will let you know if there are any corrupted data records or table indexing. And compacting will also reduce the size of the file.
While compacting the data, check if your Access subversion is up to date, so you don’t have to reissue the previous auto numbers. The copy of original MDB should also be made. In the network, do not use fields with memo data type. These fields have different indexing, which is more prone to corruption during the server write-back.
When you link tables to children tables, use auto number fields. Users find them difficult to modify and they perform better indexing. In order to prevent duplicate records, check for potential duplicate using the code, instead of using multi-field key. In the multi-user environment, avoid using record sets unless they are only read snapshot.
These are some of the most important database developing rules you should follow, in order to improve its performance speed and prevent corruption.
