Data are very important in business decision making. Businesses
collect these data from different sources internally or externally, from primary
or secondary sources. When the data are analyzed, they give insights for effective
business decision making. But then, these data need to be warehoused where they
can be retrieved when need arises. Therefore, the mechanism by which
organizations depend on to convert data into insights for effective decision
making is called database management system.
Types of Database Management System
Many different database systems exist according to how they handle or manipulate database structure. They are:
- Relational database management systems
- Hierarchical database management systems
- Network or cloud-database management systems
- Object-oriented database management systems
- NoSQL or Non-Relational database management systems
- In-memory database management systems
- Columnar database management systems
Relational
Database Management System
Relational
Database Management software include Oracle, Microsoft SQL Server, MySQL and
PostgreSQL
Oracle is
the earliest database system which was developed and commercialized since 1980. The integration of its hardware and software
is seamless. The Unix-based Oracle SQL is secured, reliable and flexible to
use.
Microsoft
SQL Server is also a reputable database system. It currently has 12 versions to
meet data size and applications of different organizations, from small
businesses to large companies. It has web edition and business intelligence
analytics tools.
MySQL: This
is an open-source DBMS owned by Oracle. It is designed to carter for small
businesses that may not afford larger RDBMSs as it costs less. The downside of
MySQL RDBMS is that its installation and maintenance require database design
and operation knowledge.
PostgreSQL
is also an open-source object-relational RDBMS that has the capability of
compiling with the ANSI SQL and SQL/MED standards. It has features that support
over 12 procedural languages and several database extensions.
Cloud-Based
DBMSs
The Cloud-based
DBMSs are types of database management software where database workload are
securely stored in the cloud, and data assets can be retrieved at any time
using any device with internet connection. The systems are managed with managed cloud
database services via DBaaS. In recent times, thee has been increase in the use
of public cloud platforms by businesses for their database management. This reduces the cost and need for
large infrastructure to run relational database management system internally. In
cloud model, companies only pay for storage, processing that they use in the
system.

The leading
cloud database services include Google Cloud Platform, Microsoft Azure and
Amazon Web Services (AWS). They all support relational, NoSQL and other types
of database systems.
Non-Relational
Database Systems (NoSQL)
As
non-Relational database systems, NoSQL function differently from SQL-based
systems in their support for structured and unstructured data. NoSQL systems
have the capabilities to collect and analyze data without a rigidly defined
schema. A NoSQL database system can process queries of database entities with
different elements, for example data that comprise text, numeric, images, video
and audio, even social media post.
NoSQL DBMS
types are Graph, document store and key-value store
In-Memory
Database Management Systems
In-Memory
DBMSs also known as Main-Memory DBMSs are types of DBMS that rely on computers main
memory to perform its task rather than on disk storage, which makes them
perform better than standard database system models. In-Memory DBMSs also use
internal algorithms that greatly decrease the processing overhead.
The major
characteristics of most main-memory DBMSs are their abilities to adhere to the ACID
properties: Atomicity, Consistency, Isolation, and Durability.
Some In-memory DBMSs are Oracle TimessTen, VoltDB, MemSQL, and NoSQL DBMSs like Aerospike and Redis
Database Management System Software
Database
Management System Software (DBMS) are database management program or suit of
programs for optimization, management, storage and retrieval of data from
database. Database software help businesses handle large data workloads.
DBMS is
structured on three important elements: data itself, database schema, database
engine. The data can be numeric, text, image, video and audio, or combinations
of these different data forms. The schema handles the logical structure, while
the engine is responsible for ensuring that the data can be accessed, locked,
and modified by the users. DBMS grants you the freedom and convenience to store
logical or physical data, and modification options to recover, monitor and
comply with business operations. Another important feature of the DBMS is its centralized
process that allows users to access data from the database from anywhere.
