....missing values) Clearly, a key challenge we face is that the number of partial structures is virtually infinite, and we will not be able to maintain all possible statistics. Hence, we will maintain only statistics on partial structures that appear frequently (discovered using techniques such as [50, 18, 39]) and estimate the statistics for other partial structures. 4.3 The Tools We now describe two interactive tools that will be built using a corpus and associated statistics and used to support components of REVERE. 4.3.1 Authoring Structured Data The first tool, DESIGNADVISOR, assists with ....

These observations motivate further work on developing storage methods and, especially, comparing native (e.g. Natix [19] or Tamino [24] and mapping based (e.g. LegoDB [5, 10]) solutions. A second one is based from the recursive study. Some document are very recursive therefore validation by usual XML validator will not work and such work like [22] may lead this new generation of research problems based on streams [11] 3.0.0.5 Future works.

Structure and Value Synopses for XML Data Graphs - Polyzotis, Garofalakis (2002) (14 citations) (Correct)
.... Summarizing a large XML data graph for the purpose of estimating the selectivity of arbitrary path expressions with value predicates is a substantially different and more difficult problem than that of constructing synopses for flat, relational data (e.g. 22, 23] Recent research studies [1, 5, 12, 24] have considered specialized variants of our XML summarization problem, focusing on the simplified case of tree structured (rather than graphstructured) data and restricted path expressions (e.g. simple paths with no branching predicates) It is unclear if these earlier techniques can be ....

The StatiX system provides concise and accurate summaries which can be easily translated into relational statistics. The translation procedure is illustrated through the example in Figure 10. The derived relational statistics are used as input to a ....

....description element need not be inlined unless it is frequently queried. 3 XML Storage with LegoDB LegoDB is a cost based XML storage mapping engine that automatically explores a space of possible XML torelational mappings and selects the best mapping for a given application. Experiments in [1, 5] show that the LegoDB mapping engine is very effective in practice and can lead to reductions of over 50 in the running times of queries as compared to previous mapping techniques. The LegoDB system is based on the following principles: Logical Physical independence. An XML application ....
....estimates obtained by a standard relational optimizer. Extend existing technologies. LegoDB develops new specific extensions to existing technologies whenever necessary. Notably, in [1] we propose novel XML Schema rewriting techniques to generate a space of possible relational mappings, and in [5], we extend XML Schema with statistics in order to support accurate cost estimation for XQuery workloads. 4 LegoDB Architecture The architecture of LegoDB, shown in Figure 4, is composed of two main components: storage design and run ( Show id INT, type STRING, title STRING, year INT, ....
