The main objective behind designing and using relational database is to store the large volumes of data without its replication or duplication. The Storage and maintenance of duplicate data will not only costs you more but also need more efforts and can also lead to wrong data analysis that further results in misinformed business decisions. So it’s the essence of every database user that the data should be maintained and avoided from duplication but still despite of solid design and mature databases, good documentation, might eventually gather the duplicate data. This article will let you know about the key concepts to protect your data from duplicity and provide you the strategies to tackle with such situations.
To prevent your data duplicity you can manually compare the databases but for even small ones it’s not an easy task. The good news that makes a smile on your face is that several comparison and duplicity checker tools are sold by third-party vendors for getting out of such troubles faced in the contents and structure of MS Access databases. The online Microsoft Office MarketPlace will avail you such features and tools. You can visit the Database management section of Office MarketPlace to check out currently featured database management tools. You have to make sure that if after taking steps to eliminate the duplicate data from tables, you still see the duplicate data in form or report, it may be due to the incorrect design of certain form or report. Now make sure that the underlying queries and tables are joined properly and that the section of report or form do not include multiple control that is bounded to same control source.

If it matters you can manually review and then delete the records. You can also update or consolidate one or multiple records before you start the process of deleting your records. Hope you will find a great help in dealing with data duplicity in database entries in MS Access with this article.
