This invention relates generally to a system for processing database queries, and more particularly to a method for generating high level language or machine code to implement query execution plans. The present invention provides a method for generating executable machine code for query execution plans, that is adaptive to dynamic runtime conditions, that is compiled just in time for execution and most importantly, that avoids the bounds checking, pointer indirection, materialization and other similar kinds of overhead that are typical in interpretive runtime execution engines.

This invention relates generally to a system for processing database queries, and more particularly to a method for generating high level language or machine code to implement query execution plans. In one preferred embodiment, the method begins by receiving a subject query, and then forming an execution plan corresponding to the subject query. The execution plan will typically have a sequence of component snippets or pieces and corresponding processes for implementing the pieces. For at least one piece in the plan, the process then (a) generates source code using different code generation techniques as a function of expected runtime processing machine types; and then (b) compiles the generated source code to form machine executable code for implementing the subject query. As a result, the query executed directly as machine executable code thereby avoiding runtime interpretation of the pieces in the execution plan.

There is provided a system and a computerized method of remediating a given program running in an operating system, the method comprising: querying a stateful model to retrieve a group of entities related to the given program; terminating at least a sub set of the group of entities related to the given program; generating a remediation plan including one or more operations linked to the given program, the one or mare operations being retrieved based on the group in the stateful model; and executing the remediation plan by undoing at least part of the one or more operations linked to the given program thereby restoring state of the operating system to a state prior to the given program being executed. There is further provided a computerized method of detecting malicious code related to a program in an operating system in a live environment.

A compilation technique for computer programs forms a data flow graph of vertices which are analysed to form clusters C for parallel execution where those clusters are added to up to the point at which arbitrary selection between further vertices C, D to be added must be made. This data flow graph with these small clusters is then scheduled such that the clusters do not overlap with other clusters or with vertices outside of clusters. This starting point scheduled data flow graph is then subject to iterative processing whereby a window of timestamps is analysed to see if a candidate cluster formed by the parallel execution of the vertices within that window will result in faster execution whilst avoiding exceeding architectural constraints, such as register occupancy. If the rescheduled vertices do improve performance without exceeding architectural constraints, then this new schedule is adopted and the following vertices are subject to an adjustment in their timestamps to account for this. A window at a different point within the schedule is then adopted and an attempted rescheduling examined. This process is repeated until no progress is being made in reducing the overall execution time.

The invention is a system and method used for teaching and learning computer programming. This system incorporates visualization, plan abstraction and its integration, and language constructs into one teaching and learning environment known as VPCL. There are three phases of VPCL, Plan Observation or Rehearsal, Plan Integration or Composition, and Plan Creation or Innovation. The observation Phase teaches how a program (plan) is broken down into smaller components known as a plan with their relationship. Each plan may further break down into smaller plans. At the last level plans are illustrated by language constructs. The integration phase concentrates on how plans are related to each other to build a program using the four methods of integration. The creation phase concentrates on how a new plan is created using the existing plans along with system resources. VPCL can be applied to other problem solving tasks such as mathematics, science, physics, chemistry, biology, or linguistics.

The invention provides a method for creating a safety closed-loop process based on MITRE ATT&CK, which comprises the following steps: 1) obtaining data to obtain an MITREATT&CK framework; 2) obtainingan opponent attack plan; 3) simulating an attack according to the opponent attack plan to obtain a simulated attack determination result; and 4) constructing an improvement plan according to a resultdetermined by the simulation attack.
