Pervasive PSQL is a relational database developed by Pervasive Software mostly used as embedded database. Originally, product name was Btrieve and it was written by Doug and Nancy Woodward.
We support Pervasive directly in our products! You don't need separate drivers and can immediately connect to your database.
Btrieve was acquired by Novell in 1987, but spun off in 1994 as a new company called Btrieve Technogies (led by Doug and Nancy Woodward and Ron Harris). Btrieve Technologies was renamed to Pervasive Software. Pervasive’s greatest strength is reliability. It’s continuously on the market for 30 years and customers report no operational problems with it. While other databases are better-known, Pervasive, being an embedded databases, get less public attention. However, it’s extremely popular and successful. Pervasive Software has 3500 partners worldwide, including 200 OEMs.
Pervasive PSQL has two database engines - relational engine (jallows you to use SQL to work with the database) and transactional engine (known also as MicroKernel Database Engine or MKDE, allows you to go directly to database and bypass SQL altogether). MKDE guarantees valid database state even in event of power loss.
All our products support Pervasive PSQL database natively. No drivers are needed, you will be able to work with Pervasive PSQL as soon as you run our applications.
It may make sense to migrate your data away from Pervasive PSQL. You may want to do it permanently or just need to share your tables with a collague in a different format.
We will copy all your tables with their data and apply indexing and relationships exactly as they are in your current Pervasive PSQL database. In a nutshell, you get exactly the same database in another database engine. Each time you run the migration, we will copy all the tables again. Of course, we have a built-in scheduler, so you can run this overnight and have a fresh database copy in the morning.
Have a need to import data from various sources into your Pervasive PSQL database? Luckily we support many popular database formats to make this easy for you. Instead of messing with exporting from source, then working your way to somehow import data into Pervasive PSQL, use our tool to copy all desired tables directly - quickly and easily.
If you have already created your target database (by yourself or using our Full Convert product), you can synchronize data in your target database with your original Pervasive PSQL database. We never pollute your databases with additional tables or triggers for replications. We never even write to your source database.
Replication allows you to update your target database very often, as we always write just a minimum of changes needed to bring databases in sync. For example, if you added three records to a single table in your Pervasive PSQL database, our replication product will write those three records to target database and nothing else. If you deleted some records, changed some others and inserted some, again – our product will pick that up and replay those changes in the target databases without touching existing data that should stay there. Our products are highly optimized for real-world workloads, so data that's inserted into different areas of table are combined and written using high-speed algorithms, as available in a specific target database.
You can run database replication often, as your target database is never empty while replication runs. You will simply see that your changes are applied on each run.
When you want a stellar SQL writing experience, our Query allows you to easily and quickly write your queries. It will autocomplete as you type and allow you to instantly view your data.
Database diagrams only get you so far. You may want to keep HTML mini-website for your database documentation so all your developers can be in the loop and quickly locate needed information. You may need it for a client report, or to distribute your database schema as a CHM file to people who need it.
Our products even allow you to upload the documentation to your FTP server, so your website copy is always current.
