Redgate's SQL Toolbelt Essentials includes industry-standard tools for SQL Server development & deployment, enabling users to include SQL Server databases in agile processes and enabilng developers to embed robust and scalable development practices.
Oracle Coherence can be used to solve latency problems by caching data near the application tier. In-memory performance helps to reduce data contention, thus improving application response time. Oracle Coherence does a great job at scaling linearly and can do so dynamically. Oracle Coherence can replicate data so it can be part of a disaster recovery solution. One thing that is often overlooked with elastic caches is their ability to analyze data in memory, leveraging the processing power of the data grid. This is something Oracle Coherence does exceptionally well. Oracle Coherence also provided event handling capabilities to allow applications to respond to events triggered by transactions.
We use SQL Compare to troubleshoot performance problems quite a bit since our data model is more like a template and not everything is 100% in sync and customization occurs between different client databases. We continually get pulled into performance issues and the developers will say Client A is performing different than Client B, why? Using SQL Compare, we usually find that one client was tuned and had indexes altered or added that weren't deployed to all clients or other objects weren't deployed correctly during the release. On the other hand, since our data model practices allow client databases to drift I tried to create a new golden image by trying to compare multiple databases based on the same data model and found it to be a very difficult process to complete using SQL Compare. SQL Compare gave me too much information and doesn't allow enough filtering to eliminate a lot of the noise.
Simple and easy comparison of database schemas and data. Differences can be copied or synced from one database to another with a click of a button.
You can save "projects" so that you can easily rerun a previous comparison whenever you need to.
It has a very simple, easy to learn interface. I've never needed to read any documentation or watch any tutorials in order to figure out how to do something.
Pricing.... I wish there was an inexpensive developer version I could buy for myself.
Portability.... I would like to use it from a flash drive so I can use it where ever I am asked to work.
Unbundled.... This may be available already but I dont' recall I can buy it cheaply as a stand-alone product. Its only part of the bundle - cost effectively.
Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.
DataSynapse GridServer has the same cache functionality connected with a grid distributed application deployment platform. It provides all the necessary tools to configure and manage these applications. On the otherhand Oracle Coherence has more a flexible configuration and better performance. Also the Oracle configuration and monitoring tools are more convenient and informative than the DataSynapse ones.
I've used Visual Studio Database Projects for this type of work in the past with some success, but Redgate SQL Compare is faster, more transparent, and simply easier to use. Faster is self explanatory. More transparent, means that it's much easier to set up your desired options for schema change deployment scripts. Easier to use, It's really dead simple. Start a project, connect your source, connect destination, click compare.
In my current project, it is yet to be decided as we are on the way to make it live for users. But I am sure it will be an added value to obtain timely calculations.
