Manual Information Systems
- Data is recorded and stored manually. This means that data is entered into a system by hand, and it is stored in physical files or documents.
- Data processing is slow and prone to errors. Manual data entry is time-consuming and error-prone. This can lead to inaccurate and inconsistent data, which can impact the quality of decision-making.
- Data access is limited. Manual information systems are typically only accessible to a small number of people, as they require physical access to the data files or documents.
- Scalability is limited. Manual information systems are difficult to scale as the volume of data increases. This is because the system is not designed to handle large amounts of data.
Computerized Information Systems (MIS)
- Data is recorded and stored electronically. This means that data is entered into a system using a computer, and it is stored in a database.
- Data processing is fast and accurate. Electronic data entry is much faster and more accurate than manual data entry. This leads to more accurate and consistent data, which can impact the quality of decision-making.
- Data access is widespread. MIS systems are typically accessible to a wide range of people, as they can be accessed through a computer network.
- Scalability is high. MIS systems are designed to handle large amounts of data, so they can be scaled as the volume of data increases.
In general, MIS systems offer a number of advantages over manual information systems. They are faster, more accurate, and more scalable. They also offer greater data access and flexibility. However, MIS systems can be more expensive to implement and maintain.
Here is a table that summarizes the key differences between manual information systems and computerized information systems:
|Manual Information Systems
|Computerized Information Systems (MIS)
|Data recording and storage
|Slow and prone to errors
|Fast and accurate
Ultimately, the best type of information system for an organization will depend on its specific needs and requirements. If speed, accuracy, and scalability are important factors, then a MIS system is likely the best option. However, if cost is a major concern, then a manual information system may be a better choice.
