Secure access of legacy databases from the Web using CORBA

Secure access of legacy databases from the Web using CORBA.
Creator

Abstract/Description
After comparing general architectures for accessing business databases from the Web, we propose a platform-independent, language-independent, object-oriented, fourtier CORBA-based architecture. The proposed architecture is presented in pattern format. Several security mechanisms are incorporated into the proposed architecture. A Web Reservation System (WRS) was created to test this architecture. Starting from an analysis pattern, a design model for the WRS was developed using the CORBA Object...
Show moreAfter comparing general architectures for accessing business databases from the Web, we propose a platform-independent, language-independent, object-oriented, fourtier CORBA-based architecture. The proposed architecture is presented in pattern format. Several security mechanisms are incorporated into the proposed architecture. A Web Reservation System (WRS) was created to test this architecture. Starting from an analysis pattern, a design model for the WRS was developed using the CORBA Object Request Broker (ORB); this was a Virtual Car Reservation System (VCRS). In the VCRS system, a user can get a reservation number when necessary information is entered from a Web browser. The user can also retrieve the reservation information by using the reservation number. All reservation information is stored in a distributed database system at a remote site. A realistic application of the proposed architecture is also described. We also provide an evaluation and comparison of the proposed architecture with other architectures.

Online advertising has built a market of hundreds of billions of dollars and still continues to grow. With well developed techniques in big data storage, data mining and analytics, online advertising is able to reach targeted audiences e ctively.

Show moreOnline advertising has built a market of hundreds of billions of dollars and still continues to grow. With well developed techniques in big data storage, data mining and analytics, online advertising is able to reach targeted audiences e ctively. Real- time bidding refers to the buying and selling of online ad impressions through ad inventory auctions which occur in the time it takes a webpage to load. How to de- termine the bidding price and how to allocate the budget of advertising is the key to successful ad campaigns. Both of these aspects are fundamental to most campaign optimizations and we will introduce both of them in this thesis. For bidding price determination, we improved the estimation of CTR (Click Through Rate) (one of the most important factors of determining the bidding price) by using a re ned hierar- chical tree structure for the estimation. The result of the experiment and the A/B test showed our proposal can provide stable improvement. For budget allocation, we introduce SCO (Single Campaign Optimization) and CCO (Cross Campaign Opti- mization). SCO has been applied by our commercial partner while CCO needs more research. We will rst introduce the methods of SCO and then give our proposal about CCO. We modeled CCO as a LP (Linear Programming) problem as well as designed an e ective procedure to implement optimal impressions distribution. Our simulation showed our proposal can signi cantly increase global Gross Pro t (GP).
