What is a Database?


A database is an electronically stored collection of structured information (data) which is well-organized. In simpler terms, it can be referred to as a systematic collection of data (facts grouped together for analysis or reference). A database management system (DBMS) controls a database. Data, the DBMS and their associated applications form the database system. Often a database system is referred to as database. Data maintained in databases can be accessed easily as well as managed, modified, updated and controlled efficiently. Structured Query Language (SQL) is used by most databases to serve the purpose of writing as well as querying data. Complex databases are developed with the aid of techniques related to design as well as modelling that are formal.

Use of Database

The internal operations of organizations are supported by their databases. A Database stores data and makes it easy to search any specific data as well as renders data sorting effortless. Another benefit is that new data can be added easily and existing data can be edited and deleted quickly and comfortably. Indexing is possible in a database. The data that is stored in it always has context which is another advantage. Metadata, which is the special information that is used to manage data, is stored by a database. A database facilitates the import of data into other applications without any challenge. Moreover, the data that is in a database can be accessed by more than one person simultaneously. It manages access rights to the data that is in it. These are the major benefits that a database provides.

Web Hosting

To digress, we use the Internet to send as well as receive data. In the context of the Internet, there are many websites that are accessible over it. We browse these websites regularly to meet our various requirements. These websites have files that are stored on the servers of website hosting companies which lease server space. Server space along with all the necessary technologies that are needed to make a website accessible over the Internet are made available through various packages by these web hosting companies. Web hosting is of many types, such as, shared, dedicated, reseller, WordPress, cloud and VPS. These various types of hosting services are frequently referred to as the “Best Linux Web Hosting”, or as the “Best Windows Shared Hosting” or as the “Top Cloud Hosting Company” depending on the type of hosting and owing to the high quality of service that these provide constantly.

Database Models’ Types

The logical structure of a database is determined by a database model. This type of a data model ascertains the manner in which data gets to be stored and organized as well as manipulated. The different ways in which data can be represented will be mentioned briefly now. Let us first touch upon simple files which are also referred to as flat files. As is evident from the name itself, it is the simplest model of database. In it the storage of all the data happens in plain text form in a file.

When we refer to another model which is the Hierarchical model, it organizes data hierarchically. There is a model that is similar to a Hierarchical model which is the Network model but its structure is more complex. A Network model makes use of records and sets for storing data. A Relational model is another widely used database model type which functions by using predicate logic and set theory.

One more type of a database model is an Object oriented model. In it objects are used to represent data. These can communicate directly with the Object Oriented Programming (OOP) language that is used. It is possible because both of these contain the same representation of the data. A hybrid of the relational model and the Object-oriented model is the Object relational model. Last but not the least is the NoSQL model which is a new type of database model. This model stores data as key-value pairs. Unlike other database models, strict hierarchy doesn’t apply to it.

Database Challenges

Some of the most common challenges that are encountered with regard to a database are ensuring the security of data, adapting quickly to any sudden increase in data volume and resolving the limitations that are related to scalability.

Final Thoughts

In today’s globalized business world, there is a constant influx of data. This data when maintained in a database can be accessed and managed easily as well as efficiently and eventually these databases can be used for superior decision-making in order to increase the efficiency and productivity of any organization.
