- Shape Analysis for Composite Data Structures
- This paper proposes a shape analysis that adapts to some of the complex composite data structures found in industrial systems-level programs. Examples of such data structures include "Cyclic doubly-linked lists of acyclic singly-linked lists", "Singly-linked lists of cyclic doubly-linked lists with back-pointers to head nodes", etc. The analysis introduces the...

- Comparing Oracle 10g column masking to relational views
- Thanks to the suggestion of TechRepublic member BrooklynPennyPincher, this Oracle tip compares two approaches to hiding column-level data on a report: the Virtual Private Database and relational views. In a previous tip, I described how a column's data could be masked hidden using Oracle 10g's Virtual Private Database...

- Three ways to speed up SQL execution in Oracle
- Oracle provides several methods for reducing the time spent parsing Oracle SQL statements, which can cause a drag on performance when executing complex queries with a large number of possible execution plans. Let’s briefly examine some of these methods.Hinting around with the ordered hintOracle must spend a great deal of...

- Build a fine-grained, event-based framework for your applications
- The most important aspects of the framework are flexibility and extendibility to satisfy software designers' demands stemming from business rules. Thus, the framework provides both blocking and nonblocking event notifications where events are delivered according to logical conditions called further as predicates. Both mechanisms are transparent for the developer and...

- A Reachability Predicate for Analyzing Low-Level Software
- Reasoning about heap-allocated data structures such as linked lists and arrays is challenging. The reachability predicate has proved to be useful for reasoning about the heap in type-safe languages where memory is manipulated by dereferencing object fields. Sound and precise analysis for such data structures becomes significantly more challenging in...

- Predicate Routing: Enabling Controlled Networking
- The Internet lacks a coherent model which unifies security in terms of where packets are allowed to go and routing where packets should be sent, even in constrained environments. While automated configuration tools are appearing for parts of this problem, a general solution is still un-available. Routing and firewalling are...

- Diverge-Merge Processor (DMP): Dynamic Predicated Execution of Complex Control-Flow Graphs Based on Frequently Executed Paths
- This paper proposes new processor architecture for handling hard-to-predict branches, the Diverge-Merge Processor DMP. The goal of this paradigm is to eliminate branch mispredictions due to hard-to-predict dynamic branches by dynamically predicating them without requiring ISA support for predicate registers and predicated instructions. To achieve this without incurring large hardware...

- Put SQL Server's EXISTS construct to good use
- EXISTS is standard SQL. Why say it's "SQL Server's"?The title says it all. Why imply that EXISTS is something specific to SQL Server?I've seen EXISTS referred to as a set comparison operator; I've seen it referred to as a predicate. I'm not an SQL expert,...

- MSDN Webcast: Security Best Practices: Hardening Your SQL Server (Level 200)
- Writing secure code is only one layer of security for your data. One needs to understand how hackers approach the data and how to build a secure database server on which one can predicate secure applications. This webcast helps developers and system administrators "harden" their Microsoft SQL Servers. Hardening involves...

- MSDN Webcast: Managing Web Services Using WS-Policy in WSE 2.0 (Level 400)
- It is common to define policy for a Web service using an XML document that includes one or more requirements for the SOAP messages handled by the service. The attendee of this webcast will learn how to implement the policy assertions supported by WSE 2.0: Security Token, Integrity, Confidentiality, Message...

- Draw Predicated Sample
- This sample uses the occlusion predicate query to avoid drawing unnecessary geometry. The scene contains four meshes, the center columne mesh, the microscope mesh, the city mesh, and the microscope occlusion mesh. The microscope mesh is a high resolution mesh that comprises the focus of the scene. Because of the...

- Understanding System Statistics
- Although system statistics haven't yet achieved much popularity, they are not only important overall but actually critical to certain optimization options in 10g. System statistics give the optimizer more of the "Truth" about how the system really performs, and therefore allow the optimizer to produce a better match between estimated...

- Comparing Oracle 10g column masking to relational views

- Predicate-Based Indexing of Enterprise Web Applications
- Searching the Web has become a commodity. However, extending applications with search capabilities is still an open research topic. Large enterprise applications such as SAP and Oracle Finance implement their own search engines. Vendors of small applications cannot afford such an investment and, as a result, small applications either do...

They are space efficient in that the predicate URI of a statement is not stored. They are time efficient in that a single database operation can store or retrieve a set of RDF...
