ABSTRACT

Business intelligence (BI) systems depend on efficient integration of disparate and often heterogeneous data. The integration of data is governed by data-intensive flows and is driven by a set of information requirements. Designing such flows is in general a complex process, which due to the complexity of business environments is hard to be done manually. In this paper, we deal with the challenge of efficient design and maintenance of data-intensive flows and propose an incremental approach, namely Co Al, for semi-automatically consolidating data-intensive flows satisfying a given set of information requirements. Co Al works at the logical level and consolidates data flows from either high-level information requirements or platform-specific programs. As Co Al integrates a new data flow, it opts for maximal reuse of existing flows and applies a customizable cost model tuned for minimizing the overall cost of a unified solution. We demonstrate the efficiency and effectiveness of our approach through an experimental evaluation using our implemented prototype.

1. INTRODUCTION

The complexity of business environments constantly grows, both with regard to the amount of data relevant for making strategic decisions and the complexity of included business processes. Today’s dynamic and competitive markets often imply rapid (e.g., near real-time) and accurate decision making. Relevant data are stored across a variety of data repositories, possibly using different data models and formats, and potentially crossed with numerous external sources for various context aware analysis. A data integration process combines data residing on different sources and provides unified view of this data for a user [1]. For example, in a data warehousing (DW) context, data integration is implemented through extract-transform- that extracts, cleans, and transforms data from multiple, often heterogeneous data sources and Finally, delivers data for further analysis. There are various challenges related to data Flow design. Here we consider two: design evolution and design complexity.

A major challenge that BI decision-makers face relates to the evolution of business requirements. These changes are more frequent at the early stages of a DW design project and in part, this is due to a growing use of agile methodologies in data Flow design and BI systems in general. But changes may happen during the entire DW lifecycle. Having an up- and-running DW system satisfying an initial set of requirements is still a subject to various changes as the business evolves. The data Flows populating a DW, as other software Artefacts, do not lend themselves nicely to evolution events and in general, due to their complexity, maintaining them manually is hard. The situation is even more critical in today’s BI settings, where on-the-fly decision making requires faster and more efficient adapting to changes. Changes in business needs may result in new, changed or removed information requirements. Thus having an incremental and agile solution that can automatically absorb occurred changes and produce a Flow satisfying the complete set of requirements would largely facilitate the design and maintenance of data-intensive Flows.

In an enterprise environment data is usually shared among users with varying technical skills and needs, involved in different parts of a business process. Typical real-world data-intensive workloads have high temporal locality, having 80% of data reused in a range from minutes to hours. However, the cost of accessing these data, especially in distributed scenarios, is often high. At the same time, intertwined business processes may also imply overlapping of data processing. For instance, a sales department may analyze the revenue of the sales for the past year, while Finance may be interested in the overall net proﬁt. Computing the net profit can largely benefit from the total revenue already computed for the sales department and thus, it could benefit from the sales data Flow too. The concept of reusing partial results is not new. Software and data reuse scenarios in data integration have been proposed in the past, showing that such reuse would result in substantial cost savings, especially for large, complex business environments. Data Flow re use could result in a significant reduce in design complexity, but also in intermediate Flow executions and thus, in total execution time too.

2. SYSTEM ANALYSIS

2.1 Requirement Analysis Existing System:

In an Existing we address these challenges and present an approach to efficient, incremental consolidation of data-intensive flows. Following common practice, our method iterates over information requirements to create the final design. we show how to efficiently accommodate a new information requirement to an existing design and also, how to update a design in lieu of an evolving information requirement. The final design satisfying all requirements comprises a multi-flow. As ‘coal’ is formed after the process and extreme compaction of layers of partially decomposed materials1, Co Al processes individual data flows and incrementally consolidates them into a unified multi-flow.

Proposed System

Following the previously proposed set of flow transformations in the context of ETL processes in Co Al we extend this set considering also the associative property of n-array operations (e.g., Join) and thus rely on the following four flow transformations used for reordering the operations. Swap Applied to a pair of adjacent unary operations, it interchanges the order of these operations. Distribute/Factorize. Applied on a unary operation over an adjacent n-array operation, it respectively distributes the unary operation over the adjacent nary operation or factorizes several unary operations over the adjacent n- array operation. Merge/Split. Applied on a set of adjacent unary operations, it respectively merges several operations into a single unary operation or splits a unary operation into several unary operations. Re-associate. Applied on a pair of mutually associative n-array operations, it interchanges the order in which these operations are executed.

4. TECHNOLOGY

4.1 ASP.NET

ASP.NET is a web development platform, which provides a programming model, a comprehensive software infrastructure and various services required to build up robust web applications for PC, as well as mobile devices.

ASP.NET works on top of the HTTP protocol, and uses the HTTP commands and policies to set a browser-to-server bilateral communication and cooperation.

ASP.NET is a part of Microsoft .NET platform ASP.NET applications are compiled codes, written using the extensible and reusable components or objects present in

.NET framework. These codes can use the entire hierarchy of classes in .NET framework.

ASP.NET web forms extend the event-driven model of interaction to the web applications. The browser submits a web form to the web server and the server returns a full markup page or HTML page in response.

All client side user activities are forwarded to the server for tasteful processing.

The server processes the output of the client actions and triggers the reactions.

Now, HTTP is a stateless protocol. ASP.NET framework helps in storing the information regarding the state of the application, which consists of:

· Page state

· Session state

The page state is the client state, i.e., the content of various input fields in the web form. The session state is the collective information obtained from various pages the user visited and worked with, i.e., the overall session state. To clear the concept, let us take an example of a shopping cart.

User adds items to a shopping cart. Items are selected from a page, say the items page, and the total collected items and price are shown on a different page, say the cart page. Only HTTP cannot keep track of all the information coming from various pages. ASP.NET session state and server side infrastructure keeps track of the information collected globally over a session.

The ASP.NET runtime carries the page state to and from the server across page requests while generating ASP.NET runtime codes, and incorporates the state of the server side components in hidden fields.

This way, the server becomes aware of the overall application state and operates in a two-tiered connected way.

The ASP.NET component model provides various building blocks of ASP.NET pages. Basically it is an object model, which describes:

ASP.NET is a technology, which works on the .NET framework that contains all web-related functionalities. The .Net frame work is made of an object-oriented hierarchy. An ASP.NET web applications is made of pages. When a user requests an ASP.NET page, the IIS delegates the processing of the page to the ASP.NET runtime system.

The ASP.NET runtime transforms the .aspx page into an instance of a class, which inherits from the base class page of the .Net framework. Therefore, each ASP.NET page is an object and all its components i.e., the server-side controls are also objects.

4.2 ADO.NET

As you develop applications using ADO.NET, you will have different requirements for working with data. In some cases, you might simply want to display data on a form. In other cases, you might need to device a way to share information with another company.

No matter what you do with data, there are certain fundamental concepts that you should understand about the data approach in ADO.NET. You might never need to know some of the details of data handling- for example, you might never need to directly edit an XML file containing data- but it is very useful to understand the data architecture in ADO.NET, what the major data components are, and how the pieces fit together.

This introduction presents a high-level over view of these most important concepts. The topic deliberately skips over many details- for example, there is much more to data sets than what is mentioned here- in favour of simply introducing you to ideas behind the data integration in ADO.NET.

ADO.Net does not continuously live connections. In traditional client/server applications, components establish a connection to a data base and kept it open while the application is running. For a variety of reasons, this approach is impractical in many applications.

Open database connections take up valuable system resources. In most cases, databases can maintain only a small number of concurrent connections. The overhead of maintaining these connections detracts from overall application performance.

Similarly, applications that require an open database connection are extremely difficult to scale up. An application that does not scale up well might perform acceptable with four users but will likely not do so with hundreds.ASP.NET Web applications in particular need to be easily scalable, because traffic to a website can go up by orders of magnitude in a short period.

A model based on always connected data can make a difficult and impractical to exchange data across application and organizational boundaries using a connected architecture. If two components need to share the same data, both have to be connected, and a way must be devised for the components to pass data back and forth.

For all the reasons, data accessed with ADO.NET is designed around an architecture that uses connections sparingly. Applications are connected to the database only long enough to fetch or update the data. Because the database is not holding onto connections that are largely idle, it can service many more users.

4.3 Overview of C#.Net

Ø C# is a simple, modern, object oriented, and type –safe programming language derived from C and C++.

· It will immediately be familiar to C and C++ programmers.

· C# aims to combine the high productivity of visual basic and the raw power of C++

Ø Visual C#.NET is Microsoft’s C# development tool.

Ø It includes an interactive development environment, visual designers for building windows and web applications, a compiler and a debugger.

Ø Visual C#.NET is part of a suite of products, called Visual Studio .NET, that also includes Visual Basics .NET, Visual C++.NET and the Jscript scripting language.

Ø The .NET frame work defines a “Common Language Specification” (CLS), a short of lingua franca that ensures seamless interoperability between CLS-complaint languages and class libraries.

Ø For C# developers this means even though C# is a new language, it has complete access to the same rich class libraries that are used by seasoned tools such as Visual Basic.NET and Visual C++.NET.

4.4 JAVA

JavaScript is an interpreter, client-side, event-based, object oriented scripting language that you can use to add dynamic interactivity to your web pages.

JavaScript scripts are written in plain text, like HTML, XML, Java, PHP and just about any other modern computer code. In this code, we will use Windows Note Pad to create and edit our JavaScript code, but there are a large number of alternatives available.

Note Pad is chosen to demonstrate JavaScript’s immediacy and simplicity.

You can use JavaScript to achieve any of the following:

· Create special effects with images that give the impression that a button is either highlighted or depressed whenever the mouse pointer is hovered over it.

· Validate information that users enter into your web forms

· Open pages in new windows, and customise the appearance of those new windows.

· Detect the capabilities of the user’s browser and alter your page’s content appropriately.

· Create custom pages “on the fly” without the need for a server-side language like PHP. JavaScript is not Java, though if you come from a Java background, you will notice that both languages look similar when written. Java is a full featured and comprehensive programming language similar to C or C++, and although JavaScript can interact with Java web applications, the two should not be confused.

Different web browsers will run your JavaScript in different, sometimes incompatible ways. In order to work around this, it is often necessary to use JavaScript itself to detect the capabilities of the browser in which it finds itself, and alter its operation depending on the result.

To revisit the original definition in this chapter, note the following points:

· Interpreted refers to the fact that JavaScript code is executed (acted on) as it is loaded into the browser. This is a change of pace from compiled languages like Java, which check your program thoroughly before running a single line of code, and can have many implications that can catch you out if you are from a non-interpreted programming background.

· Client-side has been defined already in the previous chapter.

· Event-based refers to JavaScript’s ability to run certain bits of code only when a specified event occurs. An event could be the page being loaded, a form being submitted, a link being clicked, or an image being pointed at by a mouse pointer.

· Object-oriented signals that JavaScript’s power to exert control over an HTML page is based on manipulating objects within that page.

· If you are familiar with object-oriented programming, you will be aware of some of the power that this can bring to the coding environment.

4.5 DATABASE

About Microsoft SQL Server 2008

Microsoft SQL server is a Structured Query Language (SQL) base, client/server relational database. Each of these terms describes a fundamental part of the architecture of SQL server.

A database is similar to a data file in that it is storage place for data. Like a data file, a database does not present information directly to a user, the user runs an application that accesses data from the database and presents it to the users in an untreatable format. A database typically ha two components: the files holding the physical database access data.

The DBMS is responsible for enforcing database structure, including:

· Maintaining the relationships between data in the database.

· Ensuring that data is stored correctly, and the rules that defining data relationships are not violated.

· Recovering all data to a point of known consistency in case of system failures.

Relational Database

There are different ways to organize data in a database but relational databases are one of the most effective. Relational database systems are an application of mathematical set theory to the problem of effectively organizing data. In a relational database is collected into tables called relations in relation theory.

When organizing data into tables, you can usually find many different ways to define tables. Relational database theory defines a process, normalization, which ensures that the set of tables you define will organize our data effectively.

Client/Server

In Client/Server system the server is a relatively large computer in a central location that manages a resource used by many people. When individuals need to use the resource, they connect over the network from their computers, or clients, to the server.

Examples of servers are: In Client/Server database architecture, the database files and DBMS software resides on a server. A communications component is provided so applications can run on separate clients and communicate to the database server over a network. The SQL server communication component also allows communication between an application running on the server and SQL server.

Server applications are usually capable of working with several clients at the same time. SQL server can work with thousands of client applications simultaneously. The server has features to prevent the logical problems that occur if a user.

While SQL server is design to work as a server in a Client/Server network, it is also capable of working as a stand-alone database directly on the client. The scalability and ease of use features of SQL server allows it to work efficiently on a client without consuming too many resource.

Structured Query Language (SQL)

To work with data in a database, you must use a set of commands and statements (language) defined by the DBMS software. There are several different languages that can be used with relational database; the most common is SQL. Both the American national standards institute (ANSI) and the International Standards Organization (ISO) has defined standards for SQL.

7. CONCLUSION

We have presented Co Al, our approach to facilitate the incremental consolidation of data-intensive Flows. Co Al starts from data Flows that satisfy single information requirements. Iteratively, Co Al Identifies different possibilities for integrating new data Flows into the existing multi- Flow, focusing on the maximal data Flow reuse. Finally, Co Al suggests a unified data Flow design evaluating it with the user-specified cost model. We have developed a prototype that implements the complete functionality of Co Al. We used it to evaluate the efficiency, scalability, and the quality of the output solutions of our approach, reporting the improvement of the overall execution time as well as other benifits of integrated multi- Flows. The final goal of our overall work is to provide an end-to-end platform for self-managing the complete lifecycle of BI solutions, from information requirements to deployment and execution of data-intensive Flow
