Any self-respecting activity has a Database. Not at the beginning, because it's easy that there aren't any useful contacts just opened yet, but as sales increase it's essential to have a clear idea of how many customers you have, how many are loyal and how occasional, what they have bought and how often.
Having a contact database is, in essence, the only rational way to conduct a business, regardless of the market and the type of product or service offered.
Like virtually every aspect of our lives, the contact management of a business has changed radically with the rise of digital, so we have moved from the good old address book to the Excell and finally to the Database Management System (DBMS).
What are Database Management Systems?
The Database Management System (DBMS) is a software for the storage and retrieval of user data, all with a great attention to the necessary security measures when it comes to sensitive information. It consists of a set of programs that have the task of actively managing and intervening on the database, allowing users to create specific Databases according to their needs.
DBMS are also able to accept data requests from a third-party application, allowing the operating system to provide the required information.
An example of using a Database Management System. When can it be useful?
To better understand the concept of database Management System, let's help ourselves with a very common and very close example: the database of a University.
Probably, but it depends on how we decided to organize it, we will find a Database organized in 5 files:
the file "student" stores the data of each student;
the "courses" file contains information about each course;
"sections" is the file dedicated to the storage of information relating to the different parts of a given course;
the "vote" file stores the votes received by the students;
the "tutor" file contains information about each professor.
To define a Database System we will then need:
specify the record structure of each file by defining the different types of data to be stored in each one;
possibly use a coding scheme to represent the values of a specific data item (if it is sensitive information).
Summing it up? Basically our Database thus conceived will have 5 tables with an external key defined between the various tables.
What characteristics must a good DBMS have?
Why then a Database Management System is considered, with good reason, a Software that companies cannot do without?
allows the user to make evaluations based on data abstractions;
ensures security and removes redundancy;
The DBMS allows you to create descriptive tables between the different entities and the relationships that are established between them;
follows the ACID concept (Atomicity, Consistency, Isolation and Durability);
allows multiple views of records;
enables data sharing and multi-user transaction processing;
supports a multi-user environment that allows different accounts to access and manipulate information in parallel;
offers a variety of techniques to store and retrieve data;
works as an efficient manager to balance the needs of multiple applications using the same records;
a DBMS uses various powerful functions to store and retrieve data efficiently;
offers integrity and information security.
Database Management System... as a Friend
Databases are our passion. We have worked with many realities that had the need to optimize and automate such an important and sensitive process for the health of their business and we have always gained great experiences and also learned a lot.
Our Database and data storage systems have additional fundamental and useful features in addition to the above. Any examples?
Persistence to POJO/ORM objects
SQL database design and management
Export/import Legacy Database
