A lot of companies rely on their database, because it has a lot of valuable data stored. Very often these databases can be created by employees without special database training. Having a strong database is very important for every company. So, here are mistakes that some database developers make, which can really mess up your database.

One of the mistakes is not to have a field that identifies a record as a unique one. You should always be able to tell two records apart. That is why it is important to use a unique identifier called Key Field.

Another database mistake is when database developers don’t make the fields atomic. For example, if there is a field called Name and someone enters the whole name into it, the field is not atomic. You should split the field into several ones for first and last name.

Allowing multiple entries into single field would also be a mistake. So, if the person has several phone numbers, it is a mistake to type all the phone numbers in one field. Making this mistake can make your reports very messed up. You should split the field with phone number into several fields for certain types of phone numbers.

A very big mistake is to enter everything into one big table. Storing all kinds of information like purchased items, customer, etc in one invoice table will require a lot of unnecessary data entry over and over again. Instead, break the table into three different ones such as Products, Contacts and Invoices. This way you can enter each piece of information once and then link the tables, which can share information from one another.

One more mistake is to make fields for values, which can be calculated. For example, when you need to enter age, which changes every year, you don’t want to go in and change it manually all the time. You should create a DOB field and when you need to store the age information, apply calculation, which will provide age based on the present time.

Some database developers may put a field into a wrong table. You should check each field and make sure it is placed in the correct table. Putting the same information into several places is also a big mistake, because it may lead to conflict information and space waste. Keep track of every data and avoid duplicate information in your database.

You should also make sure to give your fields specific names. To avoid confusions, when using data, you should use very significant field names that communicate with the data in the field.

Avoiding the above mistakes in creating Access database, you will be able to store and operate the data effectively.

The industry of computers and computer applications expands all the time. But you can turn this issue into your strong point by catching up with this knowledge and becoming a pro, for example in microsoft access database niche.
