The Different Types Of Databases Available For Recording And Cataloging Information

The development of databases in the field of technology saw the movement of the process of development from older hierarchical models and the ones based on the network to the object-oriented systems. In the present world, the ruling systems include the SQL databases and cloud-based databases. The changes made in the database system software are indicative of the technological advancement in this field and also on the extensive use of technology for various purposes.

The broad classification of the different systems of databases

If the databases are classified with regard to the type of content, then there are bibliographic, images, numeric and full-text databases. However as far as computing is concerned databases are mostly classified according to the parameter of the organization. The different kinds of databases which are prevalent in the present world are discussed below:

  • Relational type of databases

A relational database can be described as a tabular database. In this form of database information is defined in such a way so that it is possible to reorganize and access the data in different ways.

There are a set of tables in case of relational databases. The data fits within a category which is predefined. In a single table there is at least one category of data in a column, and in case of each row, there is a certain instance of data with regard to the categories defined in the specific columns. The interface which is used for a relational database is the Structured Query Language (SQL). It is very easy to extend a relational database. New categories of data can be added easily without disrupting the applications which already exist in the system.

  • A database that follows a distributive approach

Multiple physical locations are used for storing different portions of the data in case of a distributed database. The task of processing is carried out through dispersal and replication at different network points. There are two types of distributed databases which include homogeneous or heterogeneous types. In the case of similar database systems, the physical locations have the same hardware and run on the same kind of operating systems as well as database applications. However, in the case of heterogeneous systems the hardware, applications and operating can differ according to varying locations.

  • A database having the NoSQL approach

Huge sets of distributed information can be handled aptly by NoSQL databases. NoSQL databases are efficient in case of issues related to big data performance. The effectiveness of this type of database is apparent in an organization where the analysis of a huge amount of unstructured data is required. The data can be stored on different virtual servers.

  • A database that uses Cloud applications

This kind of database is optimized to suit a virtualized environment. These applications can have a hybrid system or a completely private one if public cloud is not preferable. The benefits of Cloud databases include the ability to acquire storage facility and bandwidth as per use. On-demand scalability along with the availability of cloud database provides enterprises the chance to sustain business applications in the form of software-as-a-service or SaaS deployment. The cloud services of extend across different platforms for managing databases effectively.

  • Databases that follow a graph method

A graph-oriented database which is also known as a graph database, is a form of NoSQL database where graphs are used to accumulate, chart and query data relationships. Databases based on the graph are primarily collections of a series of nodes and edges. The nodes represent different entities, and the edges represent the connection between different nodes. The popularity of Graph databases for examining interconnections is growing.

The multiple functions carried out by database management companies

The agencies that work with different clients for developing database systems have multiple functions to perform so that the database system that is installed for streamlining the data of the company. The work done by well-reputed database organization agencies are given below:

  • Checking the database requirements of the client’s company:

All businesses are not the same, and if a person chooses to build a database for the company, then the first task of the service provider is to specifically understand the kind of management required for the client’s company with regard to data. The database has to be developed in a suitable fashion, and the inputs have to be taken regarding any specific requirements from the client.

  • Preparation, installation, and supervision:

All the three parts are important for any service provider. The software that is to be installed for the company has to be categorically prepared and then installed. The installation has to be, and the database should function smoothly. But the task of the service provider does not end here because the database system has to be checked after installation. The supervision is the most important aspect as quick solutions to problems in case of installed databases is necessary.

  • Basing the application with the aid of virtual servers:

Virtual servers are extremely popular nowadays, and most clients prefer to have a virtual backup for data so that data loss is prevented even if the system collapses. The present-day data management service providers take the cloud-based applications into use while formulating databases so that data security is maintained at all instances. Cloud is extremely popular and allows access to users from any place which helps in cataloging and examining data easier.

Hence it can be concluded that database as software has developed in a tremendous manner since its inception and there are quite a few varieties of a database system which are functional in today’s world. While contacting and acquiring the database management services of a particular company one should ensure that the database that is being developed for installations is suited for the overall data requirements of the business enterprise.
