Introduction

In recent years, into our life is very actively introduced computer programs and computer technology. More and more information will appear. This information is necessary to collect, store and process. This is why we use the Database. Using the database, you heads of major companies will always keep information about your company, your employees information, product information and much more at your fingertips. With a database of your information will be laid out on shelves and you will always find what you need, and you will not need to look for it for a long time. Databases are very valuable in all kinds of human activity. That is why a lot of young programmers devote a lot of attention and time to study the database design. But it is not so easy as it might seem at first glance. Database design requires accuracy, knowledge, good mental abilities and a large supply of patience. I chose the topic for my database - Auto park. I believe that the database will be very relevant in our days, in every city, there are several car park and each has a large number of transport and personnel. For this information is very difficult to keep track, but here will help my database. I hope that through my database I can facilitate the work of many companies and improve the quality and speed of many of these companies.
