Advantages and Disadvantages of RDBMS
RDBMS is a product that showcases data arranged as a collection of rows and columns. And these RDBMS products follow some of the Codd’s 12 rules. With an RDBMS, it is possible to embed a collection of programs or capabilities, enabling IT and other related teams to create, edit, update, manage and interrelate with a relational database. Structured query language (SQL) is implemented by most commercial RDBMS systems for accessing the database. Some experts are of the opinion that RDBMS can run by itself without the intervention of SQL as it was developed after the introduction of the relational model.
Advantages of RDBMS
As discussed, the table format can be easily understood by the users, which makes it simpler for them to use it. The data access and data organization are arranged using a natural structure. Matching entries can be located with ease using database queries.
Accessing the Network:
An RDBMS comprises a software program, server daemon, which has been specifically designed to capture requests sent over a network, facilitating the communication between database clients and the database. Here the users are not required to log in to the computer system to access or use the database. This facilitates the users with a convenience and a security layer for your database. Developers utilize this network access facility to create desktop tools and web apps to interact with databases.
As discussed previously, an RDBMS supports a standard language that most of us are familiar with – SQL. This is mainly because the syntax of SQL is simple. It implements keywords and phrasing in the English language. This further makes it easier to learn and interpret. Sometimes, an RDBMS is known to add non-SQL database-specific keywords, functions, and features to this SQL awesomeness.
Though RDBMS does not account as the fastest known database management system structure, since it offers a number of features, such as ease and simplicity, speed is automatically overridden. There are a variety of optimizations that have been planted into the RDBMS along with the database design that further helps in performance enhancement, thereby facilitating the RDBMS to perform faster for all applications and data sets.
Technological enhancements, decrease in memory and storage costs, and increase in processor speeds are some of the factors that contribute to helping the technicians build faster systems for covering up deficiencies in the performance of the database systems.
With RDBMS, maintenance is easier as it helps the database admins or technicians to maintain, repair, control, test and even back up the databases that reside within their main system. A built-in automation system or automation tools within the RDBMS on the operating system helps in automating these functions.
User Access to More Than One Person :
As already discussed, the user access is multiple. So, more than one user can access one database at the same time. As the data is being updated or changed, users can utilize the built-in locking and transactions management functionality to access the data. This mainly helps in overcoming any possible crashes between more than one users working on the data and prevents users from accessing or using data that has been partially updated.
With the authorization and privilege control features in an RDBMS, it is possible for the database administrator to stop any access requested by authorized users. But permissions can be assigned to individual users taking into account the database activities they are intended to handle or undertake. This authorization is determined depending on the remote client IP address, which is combined with user authorization, which restricts access to selected computer systems.
Disadvantages Of RDBMS
The expense of maintaining and even setting up a database system is relatively high and one of the drawbacks of relational databases. A special software is required for setting up a relational database and this could cost a fortune. For non-programmers, they would need to implement a number of products to set up this database. It might not be an easy task to update all the information and finally get the program running. For large firms with a need for a more vigorous database, it would be imperative that you get external help from an experienced programmer to build a relational database implementing SQL. Also, you would need to get a proficient and experienced relational database administrator to manage and control this database. No matter what data you use, it is required that you ingress it from other databases, including Excel spreadsheets or text files. But you can also enter the data via the keyboard. If you intend to store highly confidential information, 2 it is required that you secure your data against any kind of unauthorized access.
