Division of databases according to architecture In this context the following stand out: singlelayer databases – these are those in which the user has direct contact with the program providing information and can immediately make changes multilayer databases – in this model the client contacts the server using appropriate drivers. In most cases singlelayer databases are used which do not burden the clientside software to such an extent and at the same time improve work efficiency.
Types of databases due to data structure This is the most commonly used division of databases. Can be replaced: simple (file) databases in which each data table is a separate document and does not cooperate with the others in the resources. Such databases are used practically only in an "analog" way and one example of such a solution may be for example a book list or a telephone book; relational databases – gained popularity in the 1980s Email Marketing List. In this system elements are organized as a set of tables with columns and rows that can work together and exchange information. It is for these databases that the SQL standard is intended; object databases – were presented in the 1990s. In these databases as the name suggests data is in the form of objects which allows you to simplify and shorten the code of the software that creates the database system;
Distributed databases – these are those that consist of data that is located on at least two different computers. They may be located in one building or in completely different locations Streaming databases – these are those in which information is presented in the form of streams. This is a solution that has not yet been refined to such an extent that it can be widely used in commercial areas. Other types of databases Other types of databases can also be mentioned: data warehouses – they are intended primarily for cooperation with analytical software e.g. business intelligence software.
