This chapter reviews the IT governance literature. It proposes that there are three different concepts that are grouped together as IT governance. These concepts are IT governance as a framework or audit process, IT governance as IT decision-making and IT governance as a branch of corporate governance. It argues that the first of these concepts is not a senior management issue, but an aid to a business process and that the remaining two concepts are complementary. The chapter recommends that the term IT governance is seen as a crucial part of the board’s wider corporate governance task, and suggests that is concerning that the view of IT governance as IT decision-making rarely pays any attention to the role of the board in a crucial decision-making process. The chapter is intended to bring together the disparate views of IT governance so as to permit a broader view of this important subject.

Image Databases (IDBs) are a special kind of Spatial Databases where a large number of images are stored and queried. IDBs have a plethora of applications in modern life, for example in medical, multimedia, and educational applications. In the framework of Geographical Information Systems (GIS), digital images (raster data) may represent changes in cultivations, sunny areas, and the discrimination between urban environments and country sides.

Apart from the raster format, GIS data may be stored in vector format (points, line segments, polygons, etc.). Each of these data formats has certain advantages making a choice between them a challenge. Raster data leads to faster computing for several operations (e.g., overlays) and are well suited for remote sensing. On the other hand, they have a fixed resolution leading to limited detail. In this article, we focus on raster data (image databases) and their indexing techniques.

Since the start of the 1980s several structures for spatial objects have been proposed in the literature for efficient storage and retrieval of image collections. Based on these methods, many kinds of useful queries on image data may be processed efficiently. These include:

  • Queries about the content of additional properties (descriptive information) that have been embedded for each image (e.g., which images have been used in the book cover of children’s books?).

  • Queries about the characteristics/features of the images like color, texture, shape etc. (e.g., find the images that depict vivid blue sky.).

  • Queries for retrieving images with specified content (e.g., find the images that contain the sub-image of a specified chair.).

  • Queries by example or sketch (e.g., a sample image is chosen, or drawn by the user and images similar to this sample are sought.).

  • Structural queries (e.g., find the images that contain a number of specific objects in a specified arrangement.).

  • Image Joins (e.g., find the cultivation areas that reside in polluted atmosphere areas.).

  • Queries that combine regional data and other sorts of spatial data (e.g., find the cities represented by point data that reside within 5km from cotton cultivations.).

  • Temporal Queries on sequences of evolving images (e.g., find if there has been an increase in the regions of wheat cultivations in this prefecture during the last two years.).

The importance of image indexing and querying techniques led major Database Management Systems’ manufacturers to embed related extensions to the core engine of their products, (e.g., DB2 has embedded QBIC technology) (Flickner et al. 1995) and Oracle provides Content-Based Image Retrieval (CBIR) based on Virage (Annamalai et al. 2000).



A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels. In a binary image, each pixel can be either black, or white, while in a greyscale (color) image each pixel corresponds to a shade of gray (to a color), among a set of permitted greyscale (color) values.

Each image represents a scene containing objects and regions. An IDB is an organized collection of digital images aiming at the management and the efficient processing of queries on this image collection. There are numerous publications in the literature related to the processing of queries on image features like color (e.g., distribution of colors, dominant colors, and color moments), texture (the pattern of the image surface change, usually expressed by a combination of characteristics like coarseness, contrast, directionality, uniformity, regularity, density, frequency, etc.) and shape (the physical structure of objects, or the geometric shapes present in the image). In several of these publications (emerging from the image processing/computer vision community) the term indexing refers to the features corresponding to each image and to the algorithm used for computing the similarity between them (the algorithm often works by an exhaustive comparison with all the images present in the databases). In this article, indexing is used in the context of databases and corresponds to the access methods (data structures) used to speed up query processing.
