    Micronaut Data

    Micronaut Data

    Ahead of Time Data Repositories

    Micronaut Data is a database access toolkit that uses Ahead of Time (AoT) compilation to pre-compute queries for repository interfaces that are then executed by a thin, lightweight runtime layer. Both GORM and Spring Data maintain a runtime meta-model that uses reflection to model relationships between entities. This model consumes significant memory and memory requirements grow as your application size grows. The problem is worse when combined with Hibernate which maintains its own meta-model as you end up with duplicate meta-models. Micronaut Data instead moves this model into the compiler. Both GORM and Spring Data use regular expressions and pattern matching in combination with runtime generated proxies to translate a method definition on a Java interface into a query at runtime. No such runtime translation exists in Micronaut Data and this work is carried out by the Micronaut compiler at compilation time.

    Moelnir

    Moelnir

    Heap organised database service (Java library)

    Moelnir is a basic database file, addressing variable record data through integer identifiers, which applies heap organisation of its data space. Advantage of Moelnir is that each record is stored in a continuous segment on the file while still record size is limit-less variable and modifiable. There are no data length limits other than the range of a 63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to non-paging internal structures.

    Dto.java and others classes - for data transmission from/to view (with EL - Expression Language" ) layer to/from business and persistence layer in J2EE application. Dto extends from HashMap class of Java API for encapsulate any type of information by key type:key_i.key_ij.key_ijk....: Any component in any J2EE functional chain can access to DTO if they know the key key_i.key_ij.key_ijk.... for object access. This project helps to decouple the data, business logic and persistence logic allowing portability between different frameworks gently.
