3 With enterprises looking to make more informed business strategies, data management becomes indispensable for decision makers today. Collation, consolidation, transfer and storage of data is more dynamic than ever before and terms such as data management, governance and metadata are now a quintessential aspect of business strategy. The biggest challenges of data management are well captured in the buzzword 'SMAC' Social, Mobility, Analytics and Cloud. The data from a controlled and structured environment has evolved to expand its scope impacting the dimensions of volume, structure, ownership and intelligence, hence bringing data governance to the forefront. It is crucial to leverage data management skills and ensure it is scalable enough to mold itself for future needs. This paper assesses the current business landscape and identifies the challenges faced in the data management domain. It recommends a two-pronged approach to the problem, which involves the use of process (through data governance) and technology (through metadata). In this paper, we propose an 'IDEAL' approach: Identify the need and stakeholders Define the scope, landscape and governance model Establish the metadata blueprint and governance body Analyse the metrics, leveraging reports and analytics to monitor deviation Liaise with the stakeholders Organizations that follow this approach will optimize their investments by factoring in the 'reuse' of existing tools in their ecosystem. Based on the principles of 'loosely coupled tightly integrated' architecture, this solution simplifies the implementation methodology for data architects.

6 1. Introduction A major challenge for decision makers today is to process and utilize the exponentially increasing quantum of data to deliver strong business results. This ever-changing data, combined with cloud/virtualization technology, is radically reshaping today's data management landscape. It has marshaled a new era where data is moving from silo systems to cloud and from tables to social media. Possibly one of the biggest challenges, and consequently, the most exciting opportunities faced by enterprises today is 'Data Management' A quick analysis of the market outlines the current challenges and key issues faced by organizations in the data management domain. The mandate for a solution is to ensure that it leverages the existing investments and implements a methodology-based process (through data governance) and technology-based approach (through metadata). This will enable the organizations to specify the policies, people, and processes needed to manage data for the purpose of delivering trustworthy, timely, and relevant information. 2. The Current Data Universe According to a white paper by International Data Corporation (IDC), there is about 500GB of data per person in the world and this is a growing figure (Source: IDC White Paper - The Expanding Digital Universe - March 2007). Although less than 30 percent of the data is created by corporations, these entities are responsible for security, privacy, and reliability of 85 percent of the data. Corporations across the globe realize that data is a valuable corporate asset and it needs to be managed effectively. With ever-increasing data volumes, real-time business intelligence, and cost controls, the bigger challenge is to prevent data defects rather than fix them. The universe of data spans across structured, semi-structured and unstructured data. Consequently, data management solutions are considering utilizing big data technologies to bring order to chaos and enable more streamlined data management processes. The data management space leverages all possible options to ensure that the knowledge facilitation is not compromised. Key trends governing data management today are: Big Data: A technology-assisted technique to facilitate processing of large data volumes effectively Cloud: A cost lever, where the obvious rendering platforms of hardware, software, and solutions are offered in a shareable model. This enables enterprises to leverage 'pay per use' concepts for effective cost benefit Mobility: Rendering data anywhere, anytime, and with effective messaging in handheld devices. This targets the 'information availability' dimension of the data management space In-memory databases: With a focus to get the right information at the right time, the technology has evolved to a state where reading from and writing to databases are eliminated to harness the computing power in memory Data virtualization: A technique to optimize storage and eliminate redundancy of data across enterprises Data management techniques have been guided by advancements in technology. Enterprises have realized the power of analytics to enforce the data management discipline, leading to faster adoption of technology levers enabling effective business plans. 6
7 Following are the key focal areas of enterprises that influence data management principles: Lowered total cost of ownership: The unexpected flood of data, higher cost of existing data management tools and market pressures have caused enterprises to look for solutions that have higher return on investment and direct impact on margins Lesser time to market: In this intensely competitive business landscape, a day's delay in TAT can have serious repercussions Improved decision making: With speed and cost taking priority, strategic and tactical insights have emerged as key factors to faster and more effective decision making. Data integrity and assurance as basic sanitary elements enable these processes On-demand availability: 'Anytime, anywhere' is a buzzword and the objective is to deliver relevant and actionable content to executives on the move Figure 1 demonstrates the relationship between business mandates and technology solutions in the data management discipline.

Challenges in Data Management With business mandates increasing pressure on IT to manage data effectively, IT faces a constant challenge to mold itself with reduced adaptation time. IT architectures have witnessed the evolution from standalone systems to Service-Oriented Architectures (SOA). The evolution period comprises consistently updating the technology landscape of enterprises. This gust of acceleration in the knowledge-rendering space needs the right infrastructural support rather than the vertical scalability noticed in the past. In the evolution of architectures, information rendering has witnessed a vertical evolution. The vertical evolution started from data being consolidated from silos to data warehouses, while the rendering techniques evolved from in-house to the Internet to hosted platforms. Cloud based solutions Enterprise Challenges Rapid evolution of architectures Data Governance Roadmap to evolve Vertical Evolution Service oriented Architectures Web Based Applications Web based with data integration Client Server Architecture with data centralization Data Challenges Data Redundancy Data Knowhow Data Quality & Assurance Standalone Desktop with data silos Figure 2. Vertical Evolution of the IT Landscape 8
9 Rendering to mobile devices finds its evolution from web based to modern mobile platforms. Significant investments have been made so far in this journey. At this maturity level, it is imperative that the next generation banks on harnessing the existing infrastructure to define an optimized architecture. The challenges and issues that the enterprises are subjected to, in order to leverage existing infrastructure, can be categorized into 'Enterprise-level' and 'Data-level'. Both these categories of challenges are correlated at the granular level. They are as follows: Enterprise Challenges Architecture adaptation: It will be difficult to quickly adapt the existing architectures to newer architectures. With lower TCO mandated by business, rebuilding a new system is not an option anymore Data Governance: Definitions, ownerships, rules, and policies are available within an organization. Unfortunately, these reside either with individuals or at very few places with easy access Building a roadmap to migrate to next generation technologies: Identification of systems that need to be moved and analysis to understand the impact of these systems Data Challenges Data redundancy: The data stores, built over a period of time, have created multiple copies or captures from different entry points Data know-how: The knowledge of what data resides where and the purpose of it is confined to very few which results in the data being underutilized Data quality and assurance: Enterprises have struggled with this aspect for long and it continues to be a challenge that needs to be addressed 4. Implementing metadata driven data governance It is evident that enterprises cannot afford to neglect the new offerings in data management. It is imperative that they adopt a well-guided approach towards effective data management, by leveraging the twin levers of data governance and technology. 4.1 Data Governance: Process Lever Data Governance is a process to effectively manage the data assets within an organization. The methodology suggested in figure 3 refers to a set of activities to be performed for successful implementation of a governance process within an enterprise. The steps defined are as follows: Define objectives, scope, roles and responsibilities, operational procedures, and performance metrics of the governance body/council Roles & Resp Data Exploitation Data Lifecycle Data Security Monitor Policies Data Architecture Define Data Governance Establish Data Quality Standards Data Creation Initiate Metadata Managemnent Master Data Management Figure 3. Data Governance Methodology Organization 9
10 Initiate communication with all key stakeholders, comprising both business and IT; identify the governance body; as well as defining roles and responsibilities of the body and individuals participating in the council Establish communication of the governance body, its roles and responsibilities and process familiarization; enable tools and techniques for monitoring and control; formulate and finalize policies, standards, and checklists for data, templates, and change management Monitor metrics and take corrective/disciplinary actions as applicable for successful implementation of the governance program Data governance plays a significant role in this solution as it is imperative that enterprises receive a buy-in from all stakeholders to address existing challenges and prepare for next-generation architectures. One of the key functions of the governance council is to ensure that the transition to the new data management offerings are brought in at the right time with the right value proposition and harnessed appropriately to maximize benefits to the enterprise. 4.2 Metadata: Technology Lever With growing data and a variety of data formats, the key challenge is to lay out a blueprint and understand the spread and behavior of data within an enterprise. Data governance is increasingly challenging in such scenarios. Effective data management involves leveraging enterprise metadata to generate insights and define points of control for the governance body. The key aspects of the solution (also depicted in Figure 4) are as follows: Identify, gather, and maintain the enterprise metadata into one single model called 'Enterprise Metamodel Governance Integrate the gathered metadata with logical integration points to create an integrated enterprise metadata Monitor Identify Define and create reports to display to measure and monitor the key metrics for data governance teams Create a well-defined governance model for sharing metrics across the enterprise Metrics Measure Enterprise Metamodel Gather Collaboration Provide supporting infrastructure for communication, collaboration, and administration to cater to operational needs of data governance Integrate Intelligence Figure 4. Metadata Lever to Support Governance 10
11 The functional architecture of the solution is depicted in Figure 5. The key components of this solution are as follows: Data Governance Information Layer Data Analytics System Layer Reports & Dashboards Administration & Management Enterprise Metamodel User Defined Metadata Enterprise Metadata Technical Metadata Business Metadata Process Metadata Content Metadata Databases Business Definitions Data Management Processes Enterprise Content Figure 5. Solution: Functional Architecture Enterprise Metadata: This comprises segregated technical, business, process, and content metadata, spread across enterprises. This metadata is identified, classified, and formatted to be fed into the system System Layer: This layer is supported by the administration and management module which supports configurations, user and process management, and housekeeping of the layer. Adapters, processes and tools gather, integrate, and provide mechanisms to access intelligence through the information layer. This layer also supports interfaces for users to enter, modify, correct or delete the metadata appropriately Information Layer: The intelligence gathered by the system processes using integrated metamodel is rendered to the data governance body/council. This layer supports analysis (slice and dice, drill downs, roll ups, lineage and so on) across the enterprise blueprint available in the system. It also offers a set of predefined reports and 11
12 dashboards to measure and monitor operational metrics for data management. The reporting module can also support 'on demand' reporting by providing a capability to create reports as per demand Data Governance: Data Governance is a body/council exercising control over enterprise data management. This solution provides role-based access to all identified roles and its respective users. Hence, it renders the right intelligence to the required bodies Data Governance System Layer (Including Information & User Interface Layer) Data Analytics Reports & Dashboards Administration & Management User Interaction Data Governance Enterprise Metamodel Process Configuration & Control Communication & Collboration Adapters - Metadata and Data Enterprise Metadata Technical Metadata Business Metadata Process Metadata Content Metadata Data Governance Databases Business Definations Data Management Processes Enterprise Content Data Layer Data Governance The technical architecture of the solution has the following components (also depicted in Figure 6): Data Layer: This is at the base of the solution landscape. It includes data stored in data stores, documents, repositories and in any other form. Enterprise Metadata: This layer qualifies the data layer by encapsulating definitions of the data. There are four types of metadata considered for this solution: Figure 6. Solution: Technical Architecture Technical metadata: This is also referred to as structural metadata. It qualifies the architecture components. Business metadata: This refers to the business definitions of the data elements, including components of business glossary, metric definitions, and common terminology. Process metadata: This refers to metadata that is generated by processes within the organization, comprising the data processes (ETL, data base logs, data flows, information refresh and so on) and business processes (EAI, alerts, thresholds among others). 12
13 Content metadata: This refers to the metadata of the content that exists in the form of documents, files, code, videos and music Adapters: The adapters, either technology specific or configurable, are built into the solution. These adapters are used to define an extract routine from the metadata stores and enable periodic refresh from the sources. The adapters for specific data processing also exist, which can be used by the system layer to build any point solutions System Layer: This is the core of the solution which consists of an enterprise metamodel that encapsulates the metadata from the categories mentioned above. This metadata is integrated, refreshed, and quality maintained by the 'process configuration and control' module. The 'communication and collaboration' module with components of messaging, workflows, s, alerts and so on provides a strong backbone to support the governance body with information rendering services. The user interface includes components of reporting and analytics, administration and management, and communication. These are interface components rendered in a user-understandable format to leverage the system functions 4.3 Rising to Data Challenges It is a challenging business mandate to ensure that data is made available and accessible to users. The following table maps the solution components that alleviate the challenges posed by the rapid vertical evolution of the IT landscape. Table 2. Challenges to Solution Mapping Challenge Area Challenge Description Solution Component Enterprise Challenge Architecture Adaptation Reporting and analytics module of the user interface layer provides capability of impact analysis for any new architecture proposition Data Governance Roadmap for Evolution Administration and management module provides a complete guidance on setting up data governance body along with roles and responsibilities; with flexibility to scale vertically and horizontally, the model can be tuned for any enterprise need Reporting and analytics module provides dependency chart and impact analysis to decide the right roadmap for the organization Data Challenge Data Redundancy Structural metadata in enterprise metamodel integrated with business metadata provides an insight to redundant data across an enterprise Data Know-how Data Quality and Assurance Integrated metadata from data models and databases, data flow diagrams, and data process metadata provides a footprint of data across an enterprise Integration of process and structural metadata in the enterprise metamodel layer with scorecards and dashboards in reporting and analytics module helps maintain data quality The solution, while addressing the current challenges, also provides an adaptable framework. This can be scaled with sufficient customization for futuristic requirements. 13
14 5. The 'IDEAL' Approach Recognizing and understanding the process and technology levers, mentioned above, alone takes a lot of analysis, effort and understanding of the complete enterprise blueprint.. It is imperative that the implementation of the process and technology levers is completed in a methodical manner. We suggest adopting the 'IDEAL' approach (concisely depicted in Figure 7) for implementing the solution: Indentify Need & Stakeholders Define Scope, Landscape, Governance model Establish Metadata Blueprint, Governance body Analyze Metrics, Reports & Analytics Liaise Workflows, Communication Figure 7. The IDEAL Implementation Approach 1. Identify need and stakeholders: Enterprises have multiple data management needs across the data life cycle from data collection, management, and analysis to preservation and archiving. Deciding what needs to be managed (process) at which point of this data management cycle and involving the right people is very critical for an organization. Sharing a vision for data management that aligns with measurable business and technical benefits will help in getting a buy-in from various organizational functions. This phase should outline the people, process and business function where the need and applicability of such a solution is higher. This will require a thorough analysis of current data management techniques, cross-functional knowledge, technology landscape and buy-in from all the stakeholders. 2. Define scope, landscape, and governance model: Defining the scope for data management projects and data governance can seem like an unnerving task. It has the potential to take on an impossibly large scope and a pervasive, enterprise-wide reach. Organizations are recommended to first start small (pilot), proving the value and capitalizing on those achievements to expand the scope. The various dimensions to define the scope and landscape are process, business function, data, and systems to be involved in the first pilot. Techniques of prioritization, ranking, and weights can be used to carve out the right portion within the organization to pilot.

Sample Governance Model 14
15 In this phase, it is important to define and socialize the governance model, which would be applicable to the organization. The people classified in the 'Identify' phase are tagged and associated with roles and responsibilities. A sample governance structure, as in Figure 8, can be used as the baseline to refine it further. Also, this phase defines the metrics to be captured and monitored by the governance bodies for effective monitoring of deployment of solutions within the organization. The metrics referring to monitoring the effectiveness of the governance model, architectural disciplines, progress on projects, and improvements in dimensions of data management (quality, security and so on) are finalized. 3. Establish metadata blueprint and governance body: This phase is also referred to as an 'Implementation' phase wherein 'process and technology' levers of the solution are implemented in the organization. It is imperative to establish an enterprise-wide footprint to give a complete picture of the organization landscape. Metrics defined in the 'Define' stage are introduced at various hotspots identified for continuous monitoring and improvement. While the technology is prepared in this phase, the governance body should also be introduced to the nuances of the solution by means of training programs and socializing of program objectives and mandates. Figure 9. Hotspots: Data Governance 4. Analyse metrics, leveraging reports and analytics to monitor deviation: The data governance body should continuously monitor the defined metrics on a regular basis to ensure that the defined priorities are progressing as planned. The technology lever of the solution should be configured with all metrics and continuously refreshed to provide the right status of the health of the scope defined. The technology lever should also have the capability to drill down to the lowest possible element to pinpoint the issues for the data governance body to decide on actionable items. 15
16 Figure 10. Data Governance Metrics Figure 11. Analyse Tools: Metrics, Dashboards 5. Liaise with stakeholders: The data governance body is provided with extensive communication methods to liaise effectively within the organization and enable tracking of the status of communication as well. The established accountability infrastructure with people or roles and communication enablers ensures the right direction of the program. We recommend adopting the 'IDEAL' approach which provides a flexible framework for organizations to leverage and customize data based on their needs. 16
17 6. Conclusion Metadata driven data governance' is a powerful tool for governance teams who can derive intelligence and monitor metrics to ensure the right analysis of data assets. Organizations, over a period of time, have made investments in technology to support their businesses. It is imperative that these should be considered in the evolution of architectures to build a cost-effective, scalable, and high-performance system. 'Metadata driven data governance', provides deeper insight and analysis capability by means of integrating metadata. However, such programs need meticulous implementation methodology wherein we recommend the 'IDEAL' methodology. 17
