By Dianne Mariz
As we live in the modern world that we have right now, we are occupied with various modifications and innovations which can improve our way of living. Moreover, these developments lead the way to a more productive life. Thus, it makes society a better place to live in.
One of the conventional technologies that we use today is the computer. A computer is an electronic device that organizes data. It can process, store, and retrieve data. The primary functions of a computer are creating documents, sending emails, playing games, and browsing the Internet. You can also prepare a spreadsheet, presentation, and video.
What is computer data?
Computer data is any information processed or stored by the computer. These data can be in various forms like texts, pictures, audio, software, application, etc. Computer data can be processed by the CPU and stored in files or folders on the hard disk.
Learn about the database and its types
A database is referred to as the collection of information in a systematic way for immediate research and retrieval of data using a computer. This platform is designed for modifying, storing, deleting, and retrieving of information in line with various operations.
You can save a database either as a single or a group of files. Different storage devices can support a database. Thus, the files on a database can be classified into records that contain various fields.
Fields refer to the primary unit of data storage. Moreover, each field contains information on the characteristic of the unit determined by the database. Meanwhile, records are categorized into tables that hold information about the relationships between various fields.
The data in databases has natural-language texts of files. There are numerical databases that are designed for finances, scientific data, statistics, and technical information. On the other hand, small databases are utilized by personal computers and users at home. As the days pass by, databases become an essential part of daily living. They now have their specific roles in the different sectors, such as office applications.
Here are some of the types of databases that you can find relevant to your needs.
- Centralized database. Users from various locations can open this type of database. The central database saves the data and sends it to a central computing unit for processing.
- Operational database. This database holds data about the operations of an organization. Operational databases are designed for production, marketing, and other business transactions.
- End-user database. End-user databases are created for the end-users like managers and shared among users. This database contains a summary of data for convenient use.
- Commercial database. These are databases that contain the information that external users need. But, it is not cost-efficient for end-users to have it by themselves. These are paid services since the database has a specific subject. For you to access the database, you will be given a commercial link. Some databases are offered through CD-ROMs. This is a way of where the cost of communication is lessened.
- Personal database. This type of database is solely for personal computers. They hold data that is used only for a limited number of users.
- Distributed database. Distributed databases use the inputs from the standard databases. The information included is shared between various websites in the organization. As the sites are connected, it builds the database of the organization itself.
Nowadays, databases play a vital role in managing data and information. It is beneficial since it makes the data easier to handle and monitors them whenever there are problems.
How does data processing work, and why is it important?
Data processing is a method where the information is collected and translated into useful information. This process should be performed correctly because it can negatively affect the results if something inadequate happens along the process.
It all starts from the raw data that you gather and then converts it to a readable format such as documents, graphs, images, etc. It appears in the form the computer can interpret and later on used by the employees in an enterprise.
Without the use of data processing, organizations have limitations on the data that they can access. Thus, it affects their growth and development when it comes to business transactions and connections. That is why companies see to it that they must understand and utilize the proper execution of data processing.
What are the stages of data processing?
Data processing is a systematic method. Therefore, it involves comprehensive stages for data processing to be successful. These stages should be followed accordingly to achieve the desired results of the organization.
- Collection. Data gathering is the first stage in the data processing. The data came from various available sources, and you must ensure that the information is pulled out from trusted sources. In this way, the data collected can yield quality results.
- Preparation. Once data collection is performed, data preparation is the next thing to do. It is also known as the “pre-processing” stage, where the raw data are organized for data processing. At this stage, the information is diligently scrutinized to check if there is any type of errors. Data preparation removes unnecessary data and starts to make high-quality information.
- Input. After the data has been cleared in the data preparation stage, it will then proceed to its corresponding destinations. Data inputs are translated into the language which the destination can understand. It is the first stage when the raw data starts to change its form to functional information.
- Processing. Data processing is the stage where the computer actually interprets the data that you have inputted. The computer uses machine learning algorithms. This process may change depending on the data source of information being processed and its intended purpose.
- Interpretation. In this stage, the processed data can now be utilized by non-data users. It is presented and readable in different forms like graphs, pictures, texts, videos, etc. Employees of a company can now use the data for personal data analysis.
- Storage. Data storage is the final stage of data processing. After all the pieces of information are processed, they will then be stored for future purposes. Some of the data can be used immediately, while others can have their specific purposes later on. When the data is correctly stored, they are easy to access when the users need it.
Competitive businesses are now getting more and more equipped with innovative data processing methods. Data processing also evolves through the cloud. Cloud technology provides convenience for the present electronic data processing techniques and increases its effectiveness and speed.
Cloud data processing platforms are affordable. Even small enterprises can have the major benefits that are not limited only to those large companies. It provides the companies the opportunity to measure without immense price tags.
Why do we need digital information?
Digital information is information stored using a series of ones, and zeros called the binary system. It is preferably used to store and read data. Moreover, you can copy, edit, and move data without losing its quality.
Computers are digital equipment that can read data as on and off. Humans interpret data via visual or auditory signals through a continuous flow. On the other hand, digital devices like computers understand information using the binary system through estimation. This estimation is known as the sampling rate. It is mixed with the amount of data included in every sample to know the accurate digital estimation.
What is digital data?
Digital data refers to the other forms of data that use specific machine language systems. Different technologies can interpret these. The most basic of these systems is the binary system. One of the significant attributes of digital data is that all types of very difficult analog input can be translated into a binary system.
In today’s modern world, digital transformation is now part of our daily lives, especially in the business sector. Growing enterprises continue to attain greatness by using trendy innovations where they can enhance their data processing system.
Here are some of the different types of data that you can possibly encounter throughout the day:
Big data as the term itself refers to the huge volume of information made by humans and machine-operated processes. Therefore, big data are not suitable for standard databases. Rob Thomas stated that as people continue to study big data, they will be able to understand why things occur. Big data is the powerhouse of information from where people can create building blocks of artificial knowledge.
Structured, unstructured, and semi-structured Data
All data have their kind of structure. Determining whether they are structured, or unstructured lie-down either it has a pre-defined data model, or it is organized in a pre-defined manner. Data structures are simple; therefore, data are usually kept in a tabular row and columnar setup of relative databases.
This type of data depends on time concept and order, which defines the data entries’ sequence, either by capturing or collecting. Time-stamped data are usually used when gathering behavioral information.
Machine data is the digital data made by systems that operate a business. This type of data includes data from different areas of industrial systems. It is considered valuable because it involves real-time data of all the activities, transactions, and devices accessed by the customers.
This data defines the location and time the same event occurred. It represents how an event in a physical location changes over some time.
Open data is readily available to anyone in terms of its usage and republishing rights without the limitations of patents, copyrights, or other types of security control.
This type of digital data is the information which is not used and lies inactive. There are instances that information is stored but later on kept unused over time.
One of the trendiest issues in analytics is the capacity to report and release real-time data. However, it does not necessarily mean that the information released happens at that exact time. Basically, it is a little bit behind the actual occurrence. Real-time data represent relevant information in specific situations. It improves the connection between customers and organizations.
Numerous data are processed everyday. These types of data have their corresponding roles in order for the data processing to proceed. However, there are some cases that important data is accidentally deleted or corrupted. To prevent this from bothering you, you can rely on storage devices to secure your data.
How can a storage device save you from a sudden data loss?
Storage devices are any type of hardware that is intended to store, transfer, and extract files and data. It can keep data both permanently and temporarily. It can also be stored in external or internal to a computer system or any computing devices. This is also referred to as the storage media.
A storage device is one of the major elements of a computing device. They virtually keep data on the computer except for the hardware firmware. Storage devices are created in different forms since it depends on the computing device.
There are two types of storage devices known as primary and secondary storage devices. Primary storage devices are usually small and temporarily store data in the internal of the computer. They also have the quickest data access and incorporate RAM and cache memory.
While secondary storage devices are commonly huge and stores data permanently. They can also be either external or internal to a computer. These devices also have a hard disk, USB storage device, an optical disk.
Different Local Storage Options
Other than the use of storage devices, there are also different local storage, which you can turn to if you want to secure your files or sensitive data. Here are the most common types of local storage for backup.
External Hard Drive
External hard drives are local storage similar to those installed on a desktop or laptop computer. The main difference is that it can be removed and separated from the computer. They can either be desktop or portable external hard drive. Though they are an excellent choice for data backups, they are vulnerable to damages.
Solid State Drive
This local storage resembles the traditional magnetic hard drives, but they differ in the internal compositions. Solid state drives do not have moving platters. They are dependent on semiconductors and electronics for storing data. Thus, it makes them reliable and more advance compared to the traditional magnetic hard drives. They are highly portable but expensive and have limited storage compared to traditional magnetic.
Network Attached Storage (NAS)
NAS is a very good choice for local data backups, specifically for small businesses and networks. It can also store a large amount of data. It is a good option for creating automated scheduled data backups. Despite its advantages, NAS is more expensive compared to single external hard drives. These are also not portable enough to be brought outdoors since they are prone to theft and other accidental circumstances.
USB Thumb Drive or Flash Drive
These local storage devices are somewhat similar to the Solid State Drives, but it is smaller in capacity and size. There are no moving portions on these devices. Thus it is easier to use. They are highly portable, wherein you can take them with you as a keychain. Flash drives are good for local data backup that you can take anywhere. Even though it is very portable, it consumes larger spaces. It is only ideal for a small amount of data.
CD or DVD
These optical drives are good for storing songs, media, movies, or applications as a gift to someone because of its low-cost attribute per disk. They are not considered as good choices for data backups. CD or DVD has a short lifespan, small storage, and slow read and writes pace. If there has been damage on the disk, everything stored in it will be useless.
For a remote storage option, cloud storage is used on commercial data centers. These storages are accessible from any computer provided that you have Internet access. A service provider commonly supports cloud storage. It is an excellent offsite data backup. It is not affected by natural disasters like floods, fires, or even criminal cases like theft.
Furthermore, the downside of cloud storage is its high cost and ongoing subscriptions as you are using it. As stated, it requires Internet access. If you don’t have it, you can’t use cloud storage. It is also slower compared to other local data backups.
Data processing is an integral part of acquiring reliable information. Modern technologies help us to be productive and creative. Furthermore, we should be responsible and observant of everything that we do. One click can change everything. It can affect you positively or negatively.
We should be wiser enough to handle every bit of information and sensitive data that we have. Modern technologies make our life easier. But, in every bright side there is a contrary. Be knowledgeable enough to handle digital problems which might arise due to modern discoveries.
