Data management and administration are essential in the daily life of companies. Today, the database has become a key element.
This tool is useful in all functions of a company, but in recent years it has come to play an important role in software development.
What is a database?
A database is a tool that allows you to collect, organize and relate data according to its type to use it or refer to it later. It is a fundamental structure for data management, and its correct operation guarantees the speed of processing, the security of the information collected, and the quality of the use of resources. To order such development, you can always turn to database software development for help.
You might think that the main goal is to store information, but this is not entirely true. A good database allows you to perform many different functions needed for software development:
- Offers flexibility and independence;
- Avoid Redundancy;
- Ensures data integrity and security;
- Allows data parallelism;
- Ability to backup and restore;
- Unlimited data management.
Classifying databases is tricky as there are many types, so we are going to categorize them based on how they organize and work with the data.
A relational database is characterized by having a structure of tables linked by well-defined relationships. It is widely used in educational institutions to link student and teacher data.
Object Oriented Database
This type of database organizes information about an object to categorize it in a memory structure. For example, we are considering a car as an object and it will be classified under the vehicle category.
As the name implies, in this type information is stored hierarchically, that is, from the most important to the least. The structure can be compared to an inverted tree, at the top we have the main node, and from there the data is classified.
This is very similar to object-oriented, with the difference that in a distributed node, it can be composed of several parts to connect to the same address.
Data warehouses are characterized by being large electronic repositories in which an organization concentrates its high-capacity data processing system.
Here, the information is processed in a transactional way, that is, it enters, stores and retrieves data from the purchase or production processes. OLTP can also be useful in accounting and other organizational areas.
This typically occurs to allow the processing of unstructured or semi-structured data. When we encounter an important data flow, in many cases the data cannot be connected in the main nodes, but it is necessary to distribute it to nodes scattered across different servers. A prime example would be Facebook.
This structure is characterized by data management in graphical mode. Graphs are mathematical structures represented by nodes or vertices connected by edges (lines or arcs).
Organization, management, and storage of data can be carried out in many ways, but it is obvious that this is the key in the vast majority of processes. https://devoxsoftware.com/hire/hire-node-js-developers/ will provide the best data analytics services to facilitate data management in companies.
