POCO C++ Libraries

Compare

  Analyzed 1 day ago

The POCO C++ Libraries (POCO stands for POrtable COmponents) are open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left ... [More] open by it. Their modular and efficient design and implementation makes the POCO C++ Libraries extremely well suited for embedded development, an area where the C++ programming language is becoming increasingly popular, due to its suitability for both low-level (device I/O, interrupt handlers, etc.) and high-level object-oriented development. Of course, the POCO C++ Libraries are also ready for enterprise-level challenges. [Less]

OrientDB

Compare

  Analyzed 3 months ago

OrientDB is a deeply scalable Document-Graph DBMS with the flexibility of the Document databases and the power to manage links of the Graph databases. It can work in schema-less mode, schema-full or a mix of both. Supports advanced features such as ACID Transactions, Fast Indexes, Native and SQL ... [More] queries. It imports and exports documents in JSON. Graphs of hundreads of linked documents can be retrieved all in memory in few milliseconds without executing costly JOIN such as the Relational DBMSs do. OrientDB uses a new indexing algorithm called MVRB-Tree, derived from the Red-Black Tree and from the B+Tree with benefits of both: fast insertion and ultra fast lookup. [Less]
