One of the most significant benefits of databases is that data can be shared or secured among users or applications. When data is allowed to be duplicated, more maintenance and system resources are required to ensure that data is always integral. When data is allowed to be duplicated, errors can happen if one instance of the data is altered and another instance remains the same. Nonduplication of data is one way of maintaining the integrity of the data.

The database software can interact with all the data in the database. Another advantage of the database approach is that, because data is located in one single database, data in different physical locations need not be duplicated. With database systems, it need only be specified what must be done, the DBMS (Database Management System) does the rest.
Organizing data in single logical repository allows for easy manipulation and querying of the data, in contrast with traditional file systems where the programmer must specify what and how the data retrieval is done. What this means is that although the data may be spread across multiple physical files, the database conveys the data as being located in a single data repository. One of the critical features of a database system is that data is stored as a single logical unit. The database system approach to data management overcomes many of the shortcomings of the traditional file system approach. By the end of this tutorial, you will know about databases, advantages of databases system over the regular file system, the steps of a database design process, software development lifecycle, qualities of a well-built database, relations and relationships, data integrity, and more. Here is a step by step approach to designing and implementing a database in your organization, using hypothetical data from a sweet shop case study. Databases are increasingly critical for the medtech / life sciences sector.
