All you need to know about databases
A database is a system that manages to sort the data and relate them to each other so that they can be easily managed by a company. It is made up of data tables that group them into rows and columns where the information is stored in a large file.
But it is essential to have a database management system (DBMS) to make the most of them and to coordinate the accesses that the programs make of the data.
MYSQL, THE DATABASE FOR EXCELLENCE
MySql is a database based GPL (General Public License) based on a server, very fast but not very useful for large volumes of data. It is considered the most popular open source database in the world. In this database, it highlights:
– Extensive subset of the SQL language. Some extensions are also included
– Availability in many platforms and systems
– Possibility of selection of storage mechanisms that offer different operating speeds, physical support, capacity, geographic distribution, transactions …
– Transactions and Foreign Keys
– Secure connectivity
– Search and indexing of text fields
ACCESS, THE MICROSOFT DATABASE
Access is another of the most common and most used databases to come included in the Office suite and combines seamlessly with Excel. With it, you can:
– Add new data to a database, such as a new item in an inventory
– Modify existing data in the database, for example, change the current location of an article
– Delete information, for example, if an item is sold or discarded
– Organize and view data in different ways
– Share the data with others through reports, email, intranet or Internet
ADVANTAGES OF DATABASES
Control over data redundancy. Since all the files are integrated, the data is not stored more than once.
It makes it much easier to maintain standards. Documentation standards, update procedures, or access rules can be easily established.
Easily share data. The database files belong to the entire company that uses them and have access to all authorized employees. And even multiple users can access the same files at the same time.
Greater security. The data is more protected against unauthorized users.
Accessibility of data. Many database management systems offer query languages that allow users to easily make any type of query without the need for a programmer to create a specific application for it.
Increased productivity. The system already offers all the typical file management routines of the application programs, so the programmer can focus on improving specific functions for the users.
Improved backup services. The current database systems minimize the time lost when a failure occurs, is restored with backups and daily backups in a simple way.
