Avoiding data loss when importing XML document into Microsoft Access

XML offers a brilliant way of storing and transporting data. Given an XML document, you can easily import data into Microsoft Access. However, depending on the structure of your xml file all or some of your data maybe imported. This article will show you how to create an XML document which can be imported into Microsoft Access without any loss of data.

Micross Access requires XML files which are element-centric rather than attribute-centric. Access also recognizes one root in a document, therefore avoid structuring your XML in such a way that there is deep nesting.

Access also enforces integrity. It ensures that no duplicate data is stored. To avoid data loss when importing data into existing fields of a table make sure that you indicate the primary key of your tables except for weak entities. For those tables with no unique fields , you can use two fields to form a composite key.

A chance to become a social media influencer

Each time a new social media app is released, you get an opportunity to become an influencer on that platform. How is that so? By creating a profile earlier than most people, you get a chance to grab the best username as well as to gain a huge following.

That opportunity is beckoning right now. The platform which is trending now is Tik Tok. It was launched on 14 September 2015 and has to date been downloaded over 500 million times. It has currently the same number of users as Twitter and it is continuing to grow.

In Zimbabwe most social media influencers are not yet on Tik Tok. I only noticed John Coles profile. This is the right moment to become famous and capitalize on the fame.
