Database management

Benefits of Database Management Systems (DBMS)


(Update: 22.04.2020)

A database management system, or DBMS, allows its users to create, read, delete, and update data in a database. The management system functions as an interface between users and / or application programs and the database to ensure that all data is well organized and easily accessible.

Within an organization, the DBMS manages three key aspects, the data, the database schema and the database engine and thus allows users to access modified and locked data. These three important aspects provide data security, concurrency, data integrity, and all other uniform administrative procedures for remote DBA support.

Take advantage of the logical and physical independence of data

A user can enjoy both the independence of logical and physical data through the DBMS. This means that the system can help the users or the applications by letting them know where all the important data is stored. The DBMS provides an application programming interface for the database. It is not necessary to modify the programs by the developers since all the changes will be made by the DBMS.

DBMSs have become popular in several industries and today more and more people rely on these systems for their effectiveness in improving data management within an organization. There are different types of DBMS available in the market, but all of them can be roughly classified as:

  • Relational Database Management System – The product can be a bit expensive, but the system is adaptable for many cases.
  • In-memory database management system – This system is widely used by enterprise sectors for its exceptional work efficiency, fast response times and better overall performance compared to other DBMS.
  • Column database management system – This system is well suited for all types of data warehouses with a large number of data elements of the same type.
  • Cloud based data management system – Here, the cloud service operators will be responsible for maintaining the DBMS.

Benefits of Database Management Systems (DBMS)

Having a DBMS within an organization offers the following advantages for organizations:

  • Check data redundancy – Instead of having multiple copies of data for each application and / or user in an organization, DBMSs enable efficient use of storage space by having centralized storage for all data.
  • Maintain data integrity – this means that the information stored in the database is always accurate and reflects the most recent state of the data. This is done by defining and enforcing data validation metrics and other integrity constraints.
  • Prevent data inconsistency – when applications have separate data, changes made to one set will not be reflected in other data sets within the company, resulting in inconsistency. DBMSs help prevent inconsistencies by eliminating data redundancy and also updating all copies of data with the latest changes made by different applications.
  • Enable data sharing – new applications / users can be developed / installed / added to the system without having to provide space for new data.
  • Enabling the application of standards – With a centralized system, it is easy to apply all requirements / standards at company, department, section and even national and international levels. Standards allow for smooth transitions during changes and migrations.
  • Activate access restriction – centralized data management via the DBMS allows multiple restrictions of users and applications according to their data needs. This limits unauthorized use of data and also improves data security.
  • Provide backup and recovery – DBMSs have robust systems to enable data recovery in the event of a failure and automatic backup of all organizational data according to predetermined schedules.
    Reduces development and maintenance costs – unforeseen demands are easily handled with DBMSs than conventional file storage systems. While the initial installation costs are high, the costs of application development and system maintenance are much lower once the DBMS is in place.
  • Activate concurrency control – a DBMS can allow multiple users to access and modify the same dataset at the same time, and reflect these changes in real time. Another aspect is that the DBMS allows multiple views for a single database schema, i.e. offering different interfaces for the same data depending on the capabilities of the user.
  • Impose data models – DMBS can be used to impose a logical and structured organization of data to allow the organization to have a consistent data system in all its parts. It also provides for a separation between the physical and conceptual schema to provide a logical database structure.
  • Allow easy modification – systems can be changed easily using DBMS to effect changes in the organization. New data can be included without damaging existing data. Additionally, applications can be isolated based on how the data is contrasted and stored in the DBMS.

Benefits of remote DBA support

Organizations around the world are looking for ways to cut costs in order to stay competitive, which means IT managers have smaller budgets to work with, hence the need for more efficient solutions. Database administration is the most technical and vulnerable sector within the IT department, as it requires a high level of mastery and skill, which is difficult to achieve.

The majority of organizations have come to the conclusion that remote database administration is the best, most affordable option compared to in-house DBA training / hiring. Here are some advantages of remote management of DBAs over internal DBAs.

  • Expert assistance – rather than hiring inexperienced junior database administrators who are expensive and can fail, remote services have the advantage of experience in a number of areas and therefore will allow for more effective and efficient management of the database. organization.
  • High availability of the database – Hiring expert services dramatically reduces downtime, as would happen when the internal DBA is unwell, leaves the company, or is unavailable.
  • Reduced costs – perhaps the greatest benefit is that the remote database administrator gives you the option of paying only for the services you really need when they are needed. This provides huge savings over paying a high fixed salary to a DBA throughout the year, including training costs to ensure they stay up to date.
  • Good for small businesses – Properly trained database administrators are very expensive which means young / small businesses cannot afford to have them on their staff. Remote DBA services allow for scale pricing, which means the business only pays for the services it actually uses. Service providers have tailor-made packages for small businesses, which they can then augment as the business grows.
  • Ensuring business continuity – Qualified DBAs are always in demand, which means that unless a company is willing to match every offer they receive, they will likely lose their DBA in favor of better offers. Remote DBA gives you constant support and management of your database, regardless of what is happening with the service provider’s staff.
  • Large knowledge base – assuming the organization decides to move from one DBMS to another, the internal DBA may not be familiar with the new system, costing the organization thousands of dollars and inefficient administration in the time needed at the DBA to learn the new system. However, remote DBA service providers have trained and experienced staff in all systems, which means your business will not be affected if you decide to move to a different DBMS.
