Purusotham Naidu 3 Associate Professor MCA Scholar MCA Scholar Department of Master of Computer Applications Sri Venkateswara College of Engineering and Technology Chittoor Abstract: Bluetooth Library Manager (BLM) is library administration programming which can be utilized as a part of any library for keeping up distinctive capacities like book inquiry, demand accommodation, information passage and so on. I have actualized this product on Android stage which has the benefit of movability and wide accessibility. I utilized Bluetooth as correspondence medium between the server and the customer. BLM has extra abilities (call, SMS, ) for correspondence between library card holder and the organization. I have executed this exceptionally for any instructive establishment which has a library having limit not more than 20,000 clients. An encryption calculation is utilized to upgrade the security of that product. This calculation is utilized for the log-in reason. Utilizing the encryption calculation we encode the watchword in the customer side and the figure content and the username is send over Bluetooth to the server side. The decoding calculation is utilized as a part of the server side to unscramble the figure - content. At that point the decoded secret word is coordinated with relating watchword of that client put away in the server side database. The client can effectively sign in into the framework if and if the secret key of the database matches with the decoded secret word. The whole database of the library is executed in a standardized manner. Understudy can present their demand from that point telephone without utilizing web. They can contact their resources and comrades through SMS, or call and the other way around. An understudy can check the accessibility utilizing this product. She/he can likewise see the arrival date of any book which is out of stock now and acquired by another understudy. Resources can likewise send any warning to any understudy through or SMS. Index words: Android, Python, SL4A, Bluetooth, SQLite, Library Management System I. INTRODUCTION These days, cell phones are turning out to be all the more capable with strengthened processors, bigger capacity capacities, wealthier diversion capacities and more specialized systems. Android Android is a portable working framework (OS) taking into account the Linux bit that is at present grew by Google. With a client interface in light of direct control, Android is composed principally for touchscreen cell phones, for example, cell phones and tablet PCs. Android is main stream with innovation organizations which oblige a prepared -made, ease and adaptable working framework for cutting edge gadgets. Bluetooth Bluetooth, which is essentially utilized for information trade, add new elements to cell phones. Bluetooth obliges low power which results to long battery life. Bluetooth innovation can be utilized inside of the scope of 30-feet, which is sensible inside of a little building. This reach can be expanded utilizing Bluetooth repeater. Besides, the information exchange rate of the Bluetooth innovation is truly adequate, i.e. 3-4Mbps. In this way, at long last, because of the aforementioned advantages, I chose to ISSN: Page 37

2 utilize the Bluetooth innovation for the network in my application. SL4A I have utilized Scripting Layer for Android (SL4A) and python for adding to my application. SL4A is a Library that permits the creation and running of scripts written in different scripting dialects specifically on Android gadget. Python Python is an abnormal state programming dialect which permits software engineer to express ideas in less lines of code. Python is broadly utilized as scripting dialect. The Java dialect is too overwhelming weight f or some and is not by any stretch of the imagination open source. Python has a wide use and is open source. It additionally has seen the most enthusiasm as far as SL4A is concerned. SQLite I have additionally utilized SQLite for my database related work. I utilize SQLite utilizing sqlite3 module for python. I have utilized the distinctive UI exteriors accessible in SL4A for client collaborations. BLM is equipped for performing distinctive capacities, for example, Searching any book, Requisition accommodation, Contact help, Book issue and so on. An encryption calculation is additionally included utilizing ASCII change and a few computations. This encryption procedure is utilized for upgrading the dependability of the product. subtle elements of a y book additionally take heaps of time as the understudy needs to go to the library and quest for that book. BLM serves to incorporate a few works of library and computerize them. It spares time of the understudies as well as. In today s world Andro id telephones are generally accessible and broadly utilized among the understudy group. So I have executed the programming in Android stage utilizing python for Android. I have executed it utilizing Bluetooth correspondence since it will help understudies to work that product anyplace in the foundation with no web association. BLM can be utilized for keeping up the diverse library works and in addition for correspondence between the resources and understudies. I likewise utilized an encryption calculation to principle the authentication of the client. To utilize the usefulness of that product both understudy and power need to log -in with his username and secret word. The verification weighing is done in the server. After effective log-in client can utilize the distinctive functionalities of that product. The establishment and upkeep expense of BLM is likewise less so it can be utilized successfully. I. Database Structure III. METHODOLOGY II. MOTIVATION Library administration programming is vital for expanding the adaptability of any library. It diminishes the work power needed for keeping up the day by day work of any library framework. In the present manual library framework a understudy need to take after a few stages for getting to any book. At first order for a book must be composed on paper and submitted to the bookkeeper. At that point she/he needs to hold up in a long line to get that book if the book is accessible. Along these lines, it can be inferred that the manual framework take bunches of time of both understudies and the library powers for getting to any specific book.
