Microsoft Access Training

March 10, 2010 By: lilybird Category: Software

After you finish your Microsoft Access training, you return to your work place, confident in your skills to create a powerful database, which will help you perform your job easier. But very soon you find out that working with the database in the classroom and at your work place is completely different and that it is not that easy to perform those tasks on your own as when the teacher did it. You should keep in mind that MS Access learning doesn’t only involve taking classes. You can take more classes, but nothing can replace personal experience. So, in order to save you some headaches, you should avoid the following common mistakes.

During your Access training you found out about different data types, which can be stored in your database, but very often the obvious data type is not the right choice. Many of us might think that phone number should be stored in the numeric field, because it is made up of numbers. But numeric field should only contain data used in calculations. And the phone number should be stored in the text field.

Another mistake to avoid, when creating your database, is storing all your data in one table. A lot of new database users have trouble understanding the relational database theory. For example, when database users try to store invoice information, which contains the list of products, customer information and other invoice information such as the date of purchase, they try to fit all this information in one table. Such practice creates wasted space and redundant information, because you have to repeat customer and product data for every invoice instead of just entering it once.

Access training should teach you that the right way to store invoice data is to create three tables with invoices, customers and products. Each item will have the unique identifier and will be entered once, but the data will be tied together.

One more common mistake is to put too much data into one field. You shouldn’t try to combine too much data in a field. Storing information about a car, you shouldn’t put model, make and year of the car in one field. This might turn into a real problem when trying to run a specific query. You are able to learn on Access database training how to combine fields, so you should always think if the data should be better separated.

You should also always consider the field size you need for storing your data, because using the default size is not always right. If your data requires only a couple of characters, using the default 50characters is just wasting space.

These are simple Access database tips, but they can help you create a better database application with fewer problems.
