You don’t need to be working at a software development company in order to understand how databases work. If you are familiar with computer technology – which I am certain you are – you would have definitely heard of something called a “Database”. Databases and database management systems are core elements of computers and software.
If you are someone who does not know much about the science of computers, you might not understand the technicalities of what a database management system is. But don’t worry, as this article will guide you through these technicalities and help you understand these concepts better.
Database software refers to systems that capture, analyze, and maintain data for business use, allowing end-users to retrieve the data when needed. Fortunately, there are many free database software solutions with powerful features that are trusted by hundreds of companies worldwide. This article will help break down the concept and uses of database programs for you and will give you a detailed description of 15 top-rated free simple database software options available for you.
What is a Database Management System (DBMS)?
Database is a collection of interrelated data. It holds information that represents the real world, is coherent and connected, and has various uses and applications. Given that the amount of data can be enormous, it is important that a database be appropriately managed. This is done using a Database Management System (DBMS).
The purpose of a database management system is simple – it manages your database. It means that it allows you to build and manage databases for different software macos applications. When the application is used by end users, a DMBS fetches relevant data on their request and makes your application function accordingly. Software applications are run in conjunction with databases. Database programs work at the background of software applications, storing, retrieving and managing information.
Database management systems use different languages to define the data elements and manipulate the data. The most common example of a DBMS language is Structured Query Language (SQL). Any database that uses this language is called an SQL software, whereas a database that uses other query languages are known as NoSQL software. These languages are used by database administrators, designers, and end-users.
There are four major types of database management systems based on different data models:
- Relational Database Management Systems: Stores and structures data based on predefined relationships between different data items.
- Hierarchical Database Management Systems: Where data in the database share a hierarchical relationship. It presents one data item as a subset of another data item.
- Network Database Management Systems: The data in the database share a many-to-many relationship. Where one data item can be linked with many other data items.
- Object-oriented Database Management Systems: The data is organized around objects, for example, multimedia records.
Now that you have understood what database management system stands for, you must be wondering how a database software is used?
Why Do We Use a DBMS?
Database management systems are used by businesses as a tool to store, maintain, and retrieve data. For businesses that deal with extensive data, a DBMS makes the data management efficient, while making the data accessible for further use. Similarly, there are databases for personal use as well.
Businesses can choose from a wide variety of commercial database management systems or even opt for an open-source database management system. DBMS selection is based on the nature of the requirements of a business and the scalability needed from a database solution. Scalability, in particular, is an important feature for businesses because it shows how well a database can operate when the usage is high. It is important for businesses to have databases that can endure high workload and can keep the application functioning so that their business can strive.
Some additional factors that are also considered when choosing a database management system for business are backup, recovery, and security features that such a system offers.
To help you understand the use of DBMS better, let’s try to understand it using the following example:
Imagine you are a business owner running a small-scale online grocery store. You would want a database for personal use to keep track of all the important information; like your sales, your customers, your inventory and related information. If you store all your information in a single spreadsheet then it can become confusing and disorganized over time. For example, if an existing customer’s address is changed, then their new order will be recorded in the same sheet against the new address. This way the same customer will have a record of two addresses (i.e. new and old) in your sheet; this redundant information will make it difficult for you to find information as shown in the illustration below.
That is why you will need a database to efficiently store and access this information. A database management system can store this information in a structured manner for you. For example, all your customers and their details like name, contact information and address can be stored in a separate table, against a unique customer ID for each customer.
The information about your products and inventory can be stored and maintained in another table. Here you can list the type of products, their price and quantity and assign a product ID for each product. If you launch or discontinue a product you can simply make a change in the product table to record it. Your orders can be tracked in a separate table where each order can have an order ID to track every single sale you make.
This way all your data can be stored in tabular form in the database, making it easier for you to maintain and access it, as shown in the illustration below.
