A database can be defined as an accumulation of information organized in a systematic way for its later use, retrieval, transmission and analysis. It is created because of the need to preserve information over time. There are many types of databases, among which we can mention the following:
According to the preservation processes, static (they are read-only, the information can be extracted, but not modified), dynamic (they handle queries, reorganization, updates, addition and deletion of information).
According to their content: bibliographic (formed by study and reading material, ordered according to author’s data, publisher, year of publication, among others), directories (they are lists with a large amount of personalized data), specialized (they contain highly specialized and/or technical information), text (they include historical or documentary texts).
Some examples of databases are public libraries, telephone directories, medical records, commercial transaction records, among others.

Database in Excel
What is a database? It is a set of data (redundancy aside) belonging to an organization, which is stored in a computer in a systematic way for later use.
Currently there are many programs to perform this function, but one of the best options is to create an Excel database, which is a fairly complete and fully accessible statistical program, you only need a computer.
Excel is a program that has many advantages, since in addition to being a statistical software, it is also mathematical, which allows through entered formulas to perform calculations in these databases. It should be noted that initially anyone can use it, but as the databases require more analysis such as percentages, etc., its use becomes more complex.
