Generate Meaningful Test Data with Data Generator for SQL Server v3.5

Posted by on August 13th, 2015

Why meaningful test data important?

While developing an application, you need to make sure you are testing it under conditions that closely simulate a production environment. Most tests rely on sample data for testing. If you manually enter data into a test environment, one record at a time using the UI, most probably, you will never build volume and variety of data that your app will accumulate in a few days in production. It is obviously that the behavior will differ. Most likely, the data you insert into a test database will be based on your own usage patterns and will not match real-world usage, leaving significant bugs untested. Read the rest of this entry »

Disabling Direct Mode In LiteDAC and UniDAC

Posted by on August 7th, 2015

LiteDAC and UniDAC interact with SQLite in 2 approaches. The first approach is that an application uses functions of the linked SQLite library. For Windows OS it is sqlite3.dll, for Mac OS and iOS – libsqlite3.dylib, for Android – The second approach allows to connect to the database from the application directly, using so called Direct Mode. Direct Mode provides interaction with SQLite avoiding any external libraries linking. It is implemented by embedding the code of the SQLite library directly to the application. This approach allows to work with SQLite in cases, when using third-party libraries is impossible due to a number of reasons. For example, when developing applications for iOS or Mac OS, the Apple corporation prohibits deployment of any libraries along with the application.

However, there are situations, when it is preferably to use the first mode. Thus, when developing applications for Android, there is no need to worry about SQLite client library presence, since it is included into this OS distribution. On the other hand, during project implementation, strict requirements may be imposed on the compiled application size. Such requirements are especially relevant for mobile development. Therefore, it is highly desirable to have an opportunity to disable modules, that won’t be used in the application, before compilation. LiteDAC and UniDAC allow to exclude the code of the SQLite client library, that implements Direct Mode, from a ready application. As a result, the size of the developed application may be decreased.
