DIFFICUIT IN FINDING IN INFORMATION. DIFFICUIT IN FINDING IN INFORMATION
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 sa…me data 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.
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.

You can try to get it more organised. You can do things like sortit. You can break it into smaller related groups to make it easierto use. You can try to keep it up to date, b…y removing data that isno longer relevant. and make sure the data is all up to date. Youcan try to remove duplicate data.
computers are like blackboards or perhaps chalk paintings on a sidewalk anything in either case can be changed with absolutely no way to ascertain when or where the chang…e was made Record is not a term associated with temporary magnets or charged capicitors manual records are made with blue black ink on paper they cant be altered without leaving traces the blue black ink is iron based starts off blue and turns black after a few years in air, it penetrates and permeates the paper, you can tell how old it is from the color. to change it you must remove all the cotton and wood fibers to the depth of penetration and reweave them with identically aged fibers then rewrite with a proper ink that has been treated to appear as old as the original document in such a way so the aging will progress at the same rate.
it is easy to carry every where. it is cheaper. it do not consume electricity.
