- How to handle optimistic concurrency violations in ADO.NET
- In database-locking parlance, the term optimistic concurrency means that your application assumes that no one else will be making changes to the same record that it is currently editing. I explored this concept in detail in a previous article, along with how ADO.NET automatically supports this locking method at the...

- Handling Data Concurrency Using ADO.NET
- This paper explores how ADO.NET is equipped to detect and handle concurrency violations. The paper begins by discussing scenarios in which concurrency violations can occur using the ADO.NET disconnected model. Then, this paper walks through an ASP.NET application that handles concurrency violations by giving the user the choice to overwrite...

- An introduction to ADO.NET concurrency
- ADO.NET is Microsoft’s new technology for working with data. One of the most trumpeted features of ADO.NET is the DataSet object, which is an object that stores data in an in-memory schema, complete with DataTable and DataRelation objects. The ability to store an entire schema in memory allows the DataSet...

- Use PERT technique for more accurate estimates
- Regardless of the technique you use, the tendency in project estimation is to provide one number for each estimate. In other words, if you have 100 activities on your schedule, each activity would have one estimate associated with it. This is generally viewed as the "most likely" estimate.In many cases...

- Conflict-Aware Load-Balancing Techniques for Database Replication
- Middleware-based database replication protocols are more portable and flexible than kernel-based protocols, but have coarser-grain information about transaction access data, resulting in reduced concurrency and increased aborts. This paper proposes conflict-aware load-balancing techniques to increase the concurrency and reduce the abort rate of middleware-based replication protocols. Experimental evaluation using a...

- Pessimistic locking solves ADO.NET concurrency problems
- One way to work around optimistic concurrency issues in ADO is to lock the records your DataSet retrieves as soon as the edit operation begins. This strategy is known as pessimistic locking. Long-duration locks generally lead to poor database performance and contention problems, but in situations where an application cannot...

- Risk Management in Optimistic Effort Estimates and Schedules With Dynamic Project Environment
- Project management is the skill to manage the project activities in a planned, organized and controlled manner. It includes general management and project monitoring for timely project completion, controlled project cost, more accurately predictable schedules, and improved organizational capabilities. Most project management decisions are made on the basis of expectations,...

- Large-Scale TCP Models Using Optimistic Parallel Simulation
- Internet data traffic is doubling each year, yet bandwidth does not appear to be growing as fast as expected and thus short falls in available bandwidth, particularly at the "Last mile" may result. To address these bandwidth allocation and congestion problems, researchers are proposing new overlay networks that provide a...

- Conflict-Aware Load-Balancing Techniques for Database Replication
- Middleware-based database replication protocols require few or no changes in the database engine. Thus, they are more portable and flexible than kernel-based protocols, but have coarser-grain information about transaction access data, resulting in reduced concurrency and increased aborts. This paper proposes conflict-aware load-balancing techniques to increase the concurrency and reduce...

- Fault-Scalable Byzantine Fault-Tolerant Services
- A fault-scalable service can be configured to tolerate increasing numbers of faults without significant decreases in performance. The Query/Update (Q/U) protocol is a new tool that enables construction of fault-scalable Byzantine fault-tolerant services. The optimistic quorum-based nature of the Q/U protocol allows it to provide better throughput and fault-scalability than...
