If you need a refresher on what a database management system (DBMS) is, this article is for you! A database management system is a tool used to create and manage databases. It requires several components to work together, including data, a database, schema and database engine.
Typically, data is represented by text, numbers and dates, while a collection of data creates a database. A schema is the blueprint of a structured database that explains the type of data stored and how it’s related. Finally, a database engine is responsible for accessing and managing the database.
Key Components of a DBMS
Aside from the database engine, there are also other components contained within a DBMS. You can think of the database engine as being the core of the database management system, and it uses the following tools to interact with the database.
Query language
A DBMS requires a database language so that it can communicate with the database. A query language is a set of commands and rules that users follow, and the most common is structured query language, or SQL.
Query processor
A query processor uses the query language to interpret queries and converts them into compatible commands for the database.
Metadata catalog
A metadata catalog is a collection of data – all about your data! Its function is to provide a deeper look into your data, such as when it was created and who it was inputted by.
Monitoring tools
The purpose of monitoring tools is to optimize performance, protect your database and reduce downtime. There are different metrics you should monitor such as CPU, memory performance and system downtime.
Quality assurance tools
Another important set of tools is quality assurance tools, which perform data integrity checks, database repair and data validations. This software is typically built into the DBMS itself.
What are the Benefits of Using a DBMS?
You might be wondering why you would need a database management system when you can create a database on its own. But there are many advantages to enjoy such as:
- Improved data security. Every time you need to access a database, it’s at risk for a security breach. With a DBMS, you can implement security policies that only let certain people access the data.
- Data integrity. Your data should be accurate and consistent so that you can make informed decisions for your business or organization.
- Privacy compliance. A DBMS can also help you manage privacy and security so that you’re always using data responsibly.
Microsoft Access is a relational database management system from Microsoft. It combines the relational Access Database Engine with a user-friendly interface and software development tools.
