The Database is an essential tool for storing and managing information in companies and organizations. It is a set of information organized in tables, which can be related to each other, allowing consultation and manipulation of stored data.
There are several types of databases, such as relational, hierarchical, networked, and object-oriented. The most widely used today is the relational database, which uses tables to store information and relationships between them.
To create a database, it is necessary to define the tables that will be used and their respective columns. Each column represents a field of information, such as name, address, telephone number, among others. It is also important to define the primary and foreign keys, which are used to relate the tables to each other.
Queries are one of the main functionalities of a database. They allow the retrieval of specific information, according to criteria defined by the user. It is also possible to perform data update, insertion and deletion operations.
In addition, the database can be integrated with other tools, such as enterprise management systems (ERP), customer relationship management systems (CRM) and business intelligence systems (BI).
