Manual database is a hard-file storage system that containsfolders, paper records, storage boxes and filling cabinets. Manualdatabase is also called as a document management s…ystem.

A manual database is a paper based database. A computerized database is one which is held on a computer in an organised manner. A computerized database is more advantageous …than manual database in terms of speed, flexibility, and ease. A manual database would normally be data held on paper. So thiscould be things like a phone book or address book, or files held ina filing cabinet. A computerised database is held on a computer inan organised and structured form. Usually this is done using adatabase application such as Oracle or Access etc. It is easy tomanipulate and extract data, so far more efficient than a manualdatabase.
1. It is time consuming to write down all the information. 2. The data is stored in registers which are stored in filing cabinets which take up a lot of space. 3. The same d…ata may get repeated over and over since the workers find it hard to keep track of documents and information. 4. Receipts and data about customers usually get misplaced during manual filing so amount of stock in account compared with the amount of stock in the store is different and trying to find and match the accounts with the stock is a tedious and time consuming task. 5. In a manual database system, information must be found by hand rather than electronically. Looking for information in a manual database may take hours searching for a particular piece of data. 6. A manual database is very vulnerable to a fire or natural disasters. 7. As there is only one copy of the data, serious problems may occur in case the file is lost or damaged or if it is needed by more than one person at a time. 8. Though there are no high electricity costs, but there is quite a lot of paper and stationery that is needed to be bought causing more storage area to be needed making it quite costly.
ADVANTAGES OF MANUAL DATABASE -It is cheaper -It dosen't consume alot of electricity -You can be exercised -It can't be deleted easily DISADV…ANTAGE OF MANUAL DATABASE -It is not that secured -It is harder -It consumes a lot of time
- Sometimes doesn't save you work. - They can break down. - It can crash. - It can shut down. - Power outage. - A hacker. - It stops working. - Virus. - Cost.
The network database model implements application logic in the data structure that limits the flexibility. In the network model, there is always the "first" in the table, and …the "last" in the table. If you read the table, you always read it the same way. The database allows you to implement "joins" as sets - and they are always ready. The "union" can be empty, it can have a first and last member and members can refer to other tables. If the systems requires a number on the invoice, you cannot store the invoice without giving it a number. But then, if the application logic changes you need to restructure the database and add indexes that the users can use to improve the new logic. If you add a field, you have to restructure the entire table (or "realm"). It is fast when used as intended, it is easy to write applications for, but is not intended for new use.
Advantages It means all of the information is together. The information can be portable if on a laptop. The information is easy to access at a…ny time. It's more easily retrievable. Many people can access the same database at the same time. Improved data security. Reduced data entry, storage, and retrieval costs. Disadvantages Database systems are complex, difficult, and time-consuming to design. Initial training required for all programmers and users. Suitable hardware and software start-up costs. A longer running time for individual applications.
Advantages of Database 1.Getting more information from the same amount of data. 2.Share data. 3.Balancing confliction requirements. 4.Controlling redundancy. 5.Facil…itating consistency. 6.Improving integrity. 7.Expanding security. 8.Increasing productivity. 9.Providing data independengce. Disadvantages of Database 1.Large file size. 2.Increased complexity. 3.Greater impact of failure. 4.More difficult recovery.
an example of a manual database is a dictionary or thesaurus.
temporal database is concept related to database store for a given timestamps so there is more storage required of storage media then simple conventional database.…
it is easy to carry every where. it is cheaper. it do not consume electricity.
the database is the data given to a computer
one is made by an onion and the other by a garlic
Disadvantages of database: 1.Number of problems are associating with centralized data. 2.cost of hardware and software. 3.complexity of backup and recovery machanism. b…y Ankit Kumar RM1001B36
A manual database takes longer to update than an automatic database. This is because all of the information must be added manually each time.
