Advantages and disadvantages of...

Oracle Database Server

Oracle Database Server is a powerful, reliable and stable database engine. It provides the highest level of data security and allows easier handling of complicated and complex queries. It is also worth remembering that Oracle Database Server provides high scalability, which supports intensive workloads and allows you to keep performance at a high level. Although the software itself is inexpensive, it can end up being pricey, as many of the features you can use with it require additional licenses.

Microsoft SQL Server

Microsoft SQL Server is an excellent tool that has so far been released in many versions. It also supports online documentation and is available in different models - on premises as well as a cloud support. It also includes many useful tools and functionalities for analysts and free tools for developers. The disadvantage of Microsoft SQL Server is certainly its high price. It's also worth keeping in mind that modifying features in MS SQL Server is difficult and complex, which can be a major setback.

 

PostgreSQL database

PostgreSQL is a highly extensible open source data analysis tool. If necessary, it is possible to add functionality according to the specific needs of a particular business. It allows processing of many complex data types, such as geographic data and contains advanced text search models. PostgreSQL supports Python, Java, Perl, PHP and other programming languages to facilitate the implementation of even more advanced data analysis functions. However, compared to other tools, its data reading speed is low, which can result in reduced performance.
