Hierarchical databases are among the most ancient forms of databases, dating back thousands of years. Records in this category are organized in a tree structure, making it simple to locate what you’re looking for. There are other smaller categories that are related at the record of records
On the network, there is a database
Additionally, network databases are one of the most well-established forms of databases. While network databases may not enable unique connections between diverse datasets at multiple levels, they do build many ties between sets by adding links (or pointers) between one set of records and another set of records, as opposed to traditional databases. The speed and flexibility of network databases have been embraced by a huge variety of enterprises, including the e-commerce sector with SAP S/4HANA Partner Malaysia.
Relational database that is text-oriented
In computing, a text-oriented database, also known as a flat file database, is a database that is kept in the form of a file (a table) that is in the txt or iini file formats. An information-storing flat file is a text file, or a file that contains both text and binary data, that is used to store information. In the majority of situations, each item in these databases comprises just one piece of information. Text-oriented databases account for the vast majority of personal computer databases.

SQL database is an acronym for Structured Query Language, which is used to create queries (relational)
- EF Codd, an IBM employee, was the first to develop a relational database, which was completed in 1970. To make the information readily accessible and reorganizable, these tabular papers are presented in a tabular format.
- Databases built on the relational model are a collection of tables that are connected to one another. The information included within these tables has been sorted into categories for your convenience. Almost every table has at least one column that relates to a certain category. A certain amount of information relevant to the category represented by each column is included inside each of the columns.
- Querying relational databases is accomplished using the structured query language (SQL), which serves as the standard application programming interface (API). Furthermore, since relational databases are easily extendable, new categories of data may be added to an existing database after it has been constructed without the need to modify any already running applications. Relational databases are becoming increasingly popular.
A distributed database is a database that may be accessed from several places at the same time
A distributed database is a database in which portions of it are stored in many physical locations, which is referred to as redundancy in the industry. In order to enhance efficiency, processing is distributed or copied among several nodes in a network.
Conclusion
Distributed databases may have either a homogeneous or a heterogeneous structure and content depending on their design. If you have a homogeneous distributed database system, all physical sites are equipped with the same hardware and run on the same operating system as the central database, as well as the same database applications. With a heterogeneous distributed database, on the other hand, a varied combination of hardware, operating systems, and database software may be found at multiple physical locations around the world.
