The handled data is called information. Information is a composed and prepared type of data. It is more important than data and is utilized for deciding. Data is utilized as the contribution for the preparing and information is the yield of this handling. This information can be utilized again in some other preparing and will be considered as data in that handling.
For instance, the signs of an understudy in various subjects are the data. To ascertain the aggregate denotes, the signs of various subjects are utilized as data and aggregate imprints are the information. Presently, to compute the normal characteristics of the understudy, this information will be prepared once more. In this preparing, the information is utilized as dała and normal imprints will be the information.
Cases of Information:
A few cases of information are as per the following:
- In schools and colleges, the crude certainties about understudies are put away on confirmation shapes. On the off chance that we need to discover a rundown of all understudies who live in Faisalabad, we will apply some handling on this data. This handling will give us the coveted rundown. This rundown is a type of handled data and will be called information.

Distinction amongst Data :
The distinction amongst Data as takes after:
- Data comprises of natural crude realities
- Data is utilized as contribution to the PC
- Data isn’t significant
- Data is typically colossal in its volume
- Data is the advantage of associations and isn’t accessible to individuals available to be purchased
- Data is troublesome or even difficult to duplicate. Assume Government loses data of statistics. It is
- relatively difficult to duplicate it
- Data is utilized once in a while
- Data is an autonomous element
- Data isn’t utilized as a part of basic leadership
- Information is the handled type of data.
- Information is the yield of PC.
- Information is significant. Information is typically short in volume.
- Information is ordinarily accessible to individuals for sale Information is simpler to recreate if lost.
- For instance, if the rundown of ignorant nationals is lost, it can be imitated effectively from put away data.
- Information is utilized as often as possible.
- Information relies upon data.
- Information is imperative for basic leadership
Metadata can be characterized as data about data. It is utilized to depict the properties and attributes of some other data. Metadata portrays the size, arrange and different attributes of data. It likewise incorporates the guidelines and limitations about data.
When you make a table, you indicate the data write, size, organize and different limitations for entering data in various fields of the table. This is metadata of the table. It portrays the properties of the data to be put away on the table. Metadata is imperative to guarantee the respectability of the data.
Record Processing System:
Customary or basic record preparing is the principal PC based strategy to deal with the business application. Previously, numerous associations put away data in documents on tape or plate. The data was overseen utilizing document preparing system. In an average record handling system, every office in an association has its own arrangement of documents.
The documents are planned exceptionally for their own particular applications. The records in a single document are not identified with the records in some other record. Business associations have utilized document handling system for a long time. Be that as it may, this system has numerous disservices.
Burdens of File Processing System:
some essential burdens of record preparing system are as per the following:
1. Data Redundancy and Inconsistency:
In document preparing system, similar data might be copied in a few records. Assume there are two documents for Students” and “Library”. The document “Understudies” contains the Roll No, name, address and phone number and different points of interest of all understudies in a school.
The record “Library” contains the Roll No and name of those understudies who get a book from library alongside the information about the leased books. The data of one understudy shows up in two documents. This is known as data excess. This repetition causes higher capacity.

There is a probability that it is changed in the Students” document and not from “Library” record. The data ends up conflicting in this circumstance.
The data in record handling system is put away in different documents. It turns out to be extremely hard to compose new application projects to recover the suitable data. Assume that understudy messages are put away in “Understudies” record and charge information is put away in “Expense” document. The data from the two records is required to send an email message to advise an understudy that the date for expense installment is finished. In document preparing system, it is hard to produce such kind of rundown from numerous records.
3. Uprightness Problems:
Uprightness implies unwavering quality and precision of data. The put away data must fulfill certain sorts of consistency obliges. For instance, Roll No and Marks of understudies ought to be numeric esteem. It is exceptionally hard to apply these obliges on records in document handling system.
4. Program Data Dependency:
Program data reliance is a connection between data in documents and program required to refresh and keep up the records.

Assume a client needs to exchange cash from account A to account B. This procedure comprises of two stages:
- Deduct the cash from account A.
- Add the cash to account B.
Assume that the system comes up short when the PC has played out the initial step. It implies that the sum has been deducted from account A yet has not been added to account B. This circumstance can make data conflicting. Record handling system does not give the office to guarantee atomicity of data.
6. Security Problems:
Record handling system does not give satisfactory security on data. In some situations,it is required to give distinctive sorts of access to data for various clients. For instance, a data section administrator should just be permitted to enter data. The director of the or ought to have the capacity to get to or erase the data totally. Such kinds of security choices are not accessible in record handling system.
7. Program Maintenance:
The projects created in record preparing system are hard to keep up. The greater part of the financial backing might be spent on support. It makes it hard to grow new applications.
