SQL-Middleware: Enabling the Blockchain with SQL
2021With the development of blockchain, blockchain has a broad prospect as a new type of data management system. However, limited to the data modeling method of blockchain, the usability of blockchain is restricted; In addition, every blockchain system has its own native but naive interfaces, when developing based on the different blockchain systems, which

ACM SIGMOD Record, 1999
For several years now, you've been hearing and reading about an emerging standard that everybody has been calling SQL3. Intended as a major enhancement of the current second generation SQL standard, commonly called SQL-92 because of the year it was published, SQL3 was originally planned to be issued in about 1996…but things didn't go as planned.

Proceedings of the VLDB Endowment, 2014
Current applications, from complex sensor systems (e.g. quantified self) to online e-markets acquire vast quantities of personal information which usually end-up on central servers. This information represents an unprecedented potential for user customized applications and business (e.g., car insurance billing, carbon tax, traffic decongestion ...

Introduction to SQL, SQL*Plus, and SQL Developer
2009This chapter provides an introduction to the SQL language and two tools for working with it. The first section presents a high-level overview of the SQL language, which will give you an idea of the capabilities of this language. Then some important basic concepts of the SQL language are introduced in the second section, such as constants, literals ...

Parallel SQL on Tandem's NonStop SQL
Digest of Papers. COMPCON Spring 89. Thirty-Fourth IEEE Computer Society International Conference: Intellectual Leverage, 2003A comparison is made of a number of different strategies for the concurrent execution of multiple SQL (structured query language) statements on a completely nonsharing multiprocessor system. The author gives some preliminary results in the form of heuristics derived from measurements on a Tandem system.

Data & Knowledge Engineering, 1994
Abstract The relational database model is defined in terms of sets, whereas SQL needs the DISTINCT option for explicit duplicate removal. We define the underlying concept of duplicate tuples, generalize the operators of the relational algebra and study the connection with logic. It is shown that ‘baggy’ operators violate classical equivalences.

SQL multimedia and application packages (SQL/MM)
ACM SIGMOD Record, 2001Regular readers of this column will have become familiar with database language SQL -- indeed, most readers are already familiar with it. We have also discussed the fact that the SQL standard is being published in multiple parts and have even discussed one of those parts in some detail[l].Another standard, based on SQL and its structured user-defined ...

Computing in Science & Engineering, 2009
In a cloud computing context, the MapReduce algorithm comprises two massively parallel operations linked by a generic sorting and data-distribution process. Although this algorithm is the workhorse in most cloud computing strategies, it's a special case of a more general dataflow.

SQL-G: Efficient Graph Analytics by SQL
IEEE Transactions on Knowledge and Data Engineering, 2019Querying graphs and conducting graph analytics become important in data processing since many real applications are dealing with massive graphs, such as online social networks, Semantic Web, knowledge graphs, etc. Over the years, many distributed graph processing systems have been developed to support graph analytics using various programming models ...

Current Geographic Information Systems (GISs) are inadequate for performing spatial analysis, since they force users to formulate their often vague requests by means of crisp selection conditions on spatial data. In fact, SQL extended to support spatial analysis is becoming the de facto standard for GISs; however, it does not allow the formulation of ...
